Off-shore power supply for magnetic bearings

Magnetic bearing technology is a solution for contact-free rotation. The rotating shaft is held in by the electromagnetic forces generated in radial and axial directions. These electromagnets require continuous power and a control system that keeps the load stable.

Customer needs and requirements

Our customer’s installations are located in isolated offshore production sites that are difficult to access. It is therefore necessary, even essential, to have reliable equipment with as little maintenance possible.

The high-speed magnetic bearing rotation renders the motor very sensitive to power loss. In case of outage, it is necessary to reduce the engine speed in order to place the shaft on a bearing. An interruption in the power supply can cause the shaft to suddenly de-levitate, forcing it to land on bearings and resulting in friction-related heating. This can cause the bearing to break or even worse, the motor to break completely. To guarantee the maximum availability of the motor, it is essential to have an energy source with at least the same level of availability.

Our customer was looking for a power backup solution that can be integrated into a cabinet developed to control the magnetic bearing equipment itself. He was looking for a power supply with high reliability and availability and a minimum of maintenance.

How did Alpha help?

Alpha Innovations’ R&D team, together with the customer’s R&D team, has developed a compact, modular and configurable UPS cabinet to secure power supplies and to protect the equipment in case of a power outage.

The solution


Alpha Innovations’ team designed a fully customized solution based on this customer’s requirements. The solution consists in a compact cabinet with UPS and internal batteries. The UPS delivers 300Vdc and a backup time of 5 to 10 minutes (depending of the configuration). This gives the necessary time (2 minutes) to check the lines and (3 minutes) to slow down the speed of the rotor in case of a power outage and most of all to protect the equipment. Most power outages are less than 2 minutes. When a power outage lasts longer than 2 minutes, this generally means that it may last a few hours.

Alpha’s solution is driven by a controller that is in continuous communication with the bearing controller. Keeping both controllers separate can improve the maintenance practices and reduce safety risks as operators can work in one area without affecting the other.




Keys to success


The reliability of the UPS is essential: as the rotor speed is very high, in case of an interruption of the main, a procedure to stop the rotor has to be launched to slow it down  before a complete stop. An immediate stop at full speed could destroy the bearing or even the motor itself.


The intensive collaboration between Alpha Innovations’ R&D and the R&D team of our OEM customer has been the key factor for the success of this project. Both teams confronted the task to design power interaction, both for hardware and firmware.


The capacity of Alpha Innovations to customize its power converters and its monitoring solutions, coupled to its experience in designing power systems, have been an important factor so as to deliver a configurable product family, optimally fitted for the final application. In order to provide even more availability, Alpha Innovations is now developing a load analysis and a predictive maintenance system for this customer.

Ensuring metro passengers’ safety and comfort with Platform Screen Doors

Every day millions of travelers use the subway all over the world. When transporting people by metro, it is necessary to keep them safe, to provide them with comfort and to limit their waiting time to a minimum. This is what Platform Screen Doors (PSD) are made for.

Platform Screen Doors (PSD)

Platforms screen doors consist in automatic doors along platforms to isolate travelers from the subway traffic. They work as a barrier installed at the edge of the platforms and are synchronized with the on-board doors of the train.


Metro operating companies are implementing platform screen doors when revamping stations, automating the lines or building new lines. However, their goal remains the same: increase passengers’ safety and comfort as well as the efficiency and reliability of the transportation.

In order to do this, metro operating companies are looking for long-term and flexible solutions enabling the platform screen doors to be operational 7/7. To ensure a high level of service, reliable power and supervision solutions are essential. That is where Alpha Innovations comes in to deploy its expertise.

Alpha Innovations’ solution

Power Supply

Voltages and signals to control the door motors can vary depending on the motor types as well as the control systems. Thanks to our wide range of modules, we are able to combine the right converters with the right voltages, in AC or in DC. Moreover, our converters are compliant and compatible with railway signaling architecture requesting specific insulations for instance.

We often collaborate with platform screen door suppliers for the assembly and tests of complementary functions designed by them and integrated inside the power cabinets or in the external cabinets.

Our power supply solutions include converters, their protections and controls as well as a power backup.

Power backup and reliability can be ensured by different means:

  • Redundancy of the sources: two sources of power - when one fails, the other one takes over
  • Integration of batteries in the power system: when the grid is not available, batteries will power the PSD systems with a 0ms transfer time
  • Redundancy of the DC and AC converters

Metro operators sometimes combine these means. We have experience with all these situations and can deliver the means they need in a single power cabinet.

Monitoring & Control

Our power supply solutions are placed in technical rooms together with other equipment of the metro station infrastructure. Our monitoring and control solutions not only manage our power systems, they can also manage all equipment inside and outside the technical rooms such as third-party sensors and components along the tracks. 

For example, our local Compas controller can be integrated into any cabinet and report status (power source, alarms, …) through various communication bus. We also offer a multi-site supervision and management solution, Armada, to have a real-time overview and control of the entire infrastructure enabling the anticipation of components’ end-of-life.

All this enables metro operating companies to ensure the continuity of their services and ease maintenance in a complex environment by providing a summary view of their infrastructure.

Why they trust us?

Subway infrastructures imply huge investments and few changes over time. Therefore, metro operating companies are looking for long-term suppliers. We make it a point of honor to do everything we can to ease our collaboration. How?

Documentation & Tests

As a supplier, we commit to assist our customers for 20 to 30 years. To do this, a complete and up-to-date documentation is mandatory. Both Alpha Innovations employees and our customers’ employees can access every document related to the installation.

Another way to make sure our installation is reliable is to perform functional and security tests. Indeed, functional tests show that our system covers all the mandatory functionalities.

The security tests of our system can vary from one country to another, and we always make sure they are compliant with local standards and norms.

Obsolescence management

One of our strengths is the modularity of our systems facilitating the replacement of any component in case of an obsolescence announcement, without replacing the whole installation.

All around the world

We have a large field experience in power supply and monitoring for Platform Screen Doors, all over the world.

Alpha Innovations power supplies are equipping cutting-edge Medical devices worldwide

State-of-the-art medical devices need a dedicated power supply overperforming in safety, reliability, flexibility, while achieving the best cost-effectiveness. Alpha Innovations is the ideal partner to develop and deliver worldwide custom power solutions compatible with innovative medical technologies. Here is how we co-innovate with major medical devices manufacturers.

Dialysis machine




Medical device manufacturers are pressured to ensure safety compliance throughout the production process. Electrical leakage to both patients and operators is a significant concern. Therefore, power supplies must meet the requirements of the IEC 60601-1 product safety standard related to electrical medical equipment.



In medical devices applications, the space for electronics is very limited. Therefore, whether electrically or mechanically, power supplies of medical devices need to perfectly fit the machine. The medical technology cannot adapt to the power-supply; the supply must enable the technology.


Availability and reliability

Medical devices are run by caregivers, not by technicians and require 24/7 operation of critical equipment. To meet this challenge, reliable power supplies and high lifetime expectancy are expected from medical devices manufacturers.


Flexible and Scalable

Medical technologies are constantly evolving, and the number of patients is increasing every day. As a consequence, manufacturers need flexible and scalable solutions to meet the changing requirements of the medical devices market. They need a partner able to deliver a custom solution as smoothly as any standard component.


Alpha Innovations’ solution



Protecting the patients and operators

Protecting the patient is a mission that we collectively share and valorize. Behind our agility to over-deliver in crisis times, we see each individual that will receive cares.

On top of matching the IEC 60601-1 product safety standard, our adapted power supplies are compliant with risk management on the equipment level. For example, our converters are integrated into dialysis equipment where water, electricity and chemistry or heat are present. This led to specific requirements and features fulfilled by the Alpha Innovations’ converters.


Mechanically and electrically tailored solution

We provide dedicated design that can be massively produced at good price. The social challenge is to have enough cost-effective equipment to treat an always increasing number of patients.

Mechanically, our solutions perfectly adapt to the equipment, ensuring not only the smallest footprint, but really fitting-in the device. Electrically, above the safety standard, it ensures the highest efficiency. Moreover, we offer a full service and a long-term availability of system components.


Adapted to the market’s changes

Because we work together with medical device manufacturers for many years, we are able to seize the market’s challenges and adapt our solutions to them.  As a consequence, Alpha Innovations quickly reacts to the market demands, especially these last months during which the COVID-19 has obliged the healthcare services to duplicate essential equipment, such as dialysis. Our flexibility and reactivity have been recognized by our customers.

First step of our Energy Storage installation

At Alpha Innovations, we are more than convinced by energy storage solutions. Therefore, it was more than logical for us to install our own. The installation of more than 150 kWp solar panels in our plant in Belgium is a first step… and it has now been completed!

Part of the PV installation on our roof


In order to reduce the electricity bill, secure the power supply of critical equipment, and optimize the use of renewable energy production, the energy storage systems are the ideal solution for Commerce & Industries. By sustaining the grid, the energy storage solutions also help with grid stabilization which becomes increasingly difficult. It will also help to face power outages that will only increase in the future.

Moreover, as a member of the CE+T Group, we can count on other companies in the Group specialized in this field: CE+T Energrid (for customers in EMEA, Asia and Australia) and CE+T Energy Solutions (dedicated to the American market).

For all these reasons, we believe in energy storage solutions and we decided to equip our site with our own storage installation.


For this first step, we installed 467 solar panels of 335Wp each on the roof of our plant in Louvain-la-Neuve (Belgium). With this installation, about 145 MWh of energy should be produced each year. This step was completed during the COVID-19 confinement along with 8000 m² roof insulation.

The next step is currently in progress. It consists of the installation of Hercules, modular power converters from CE+T Energrid as well as 75 kW batteries. By combining all these components with Compas, our Energy Management System (EMS), we will benefit from a complete Energy Storage installation.


Alpha Innovations is now even more eco-responsible with the capacity to produce 145 MWh of energy each year. Once the complete energy storage system is operational, we can increase our self-consumption (by consuming our green energy) and reduce our peaks. As a consequence, our energy bill will also be significantly reduced. We will share more details about this installation in the coming months, stay tuned!

Don’t hesitate to contact us for more details and to learn about our energy management solutions.

User case: one monitoring, multiple sites

  • Market: Transport
  • Application: infrastructure management and maintenance
  • Solution: Monitoring for infrastructure with one single interface
  • Customer: Major actor in European Railway

User Case - Maintenance on train track

Problems and needs

Railway operators aim at going from one point to another, avoiding unexcepted interruption and delays, at the best cost possible.

When a problem occurs along the tracks, due to any internal or external cause, the train is automatically blocked for security reasons. A blocked train is costly (it can quickly rise to thousands of euros) and requires a team of technicians.

Therefore, Alpha Innovations’ customer was looking for a solution that would enable them to anticipate such situations and to reduce the time of breakdown as well as the intervention costs.

Alpha Innovations’ solution

Preventive maintenance helps keeping equipment up and running by preventing unexpected downtime or failure. How? By collecting data from all the infrastructure, problems can be detected before they occur.

To go even further, predictive maintenance provides statistics and know-how based on what already happened in order to improve both the knowledge of the equipment and the maintenance organization.

How we do it?

In collaboration with our customer’s team of specialists, who know the sensitive parameters of their equipment, the Alpha team translated this information into a customized software solution. Therefore, failures can be anticipated by monitoring the parameters identified.

Concretely, the information is sent from the controller inside the cabinet (Compas) to the control room through our monitoring solution (Armada). All in all, the combination of modules, controller and monitoring software should provide all the necessary tools and equipment to track any deviation due to alarm reports.

Receiver and transmitter

The module inside is receiver and transmitter. It can detect the presence of the train on the track. It is part of our customer’s audio frequency track-circuit solution. When it is down, the train is blocked. Therefore, predictive maintenance should be done on these modules.


The Universal Compas Controller (UCC) receives different types of signals from the modules. When this happens, the controller sends alarms via a secured communication bus to a server in the control panel room. From there, the data is collected and visualized into live reports thanks to the Armada software.


The solution Alpha Innovations proposed was to develop a specific monitoring system compatible with our customer’s modules. The monitoring software, Armada, is able to analyze multiple types of signals and communicate them to an external controlling device. The monitoring equipment is able to prevent upcoming breakdowns. As a consequence, the time and costs of technical interventions are reduced.

Impacts for the customer

Security of workers

As the solution provided enables to anticipate the interventions, they can be planed, outside of traffic hours. This results in a safer and more ergonomics way of working for maintenance workers, who are very exposed.

Efficient maintenance

Depending on the type of alarm, one or more technicians go on-site to proceed with the maintenance. With our solution, the technician can go directly to the correct site and with the adapted tools. Indeed, he already knows precisely what needs to be done, in which cabinet and for which component. Moreover, he has access to all the documentation about the cabinet he has in front of him.

Reducing costs

The solution is not only practical, it is also cost-effective.

One monitoring platform

Having one single platform for monitoring instead of multiple interfaces reduces costs. Indeed, the training takes less time, the information is quickly available and in case of maintenance or failure, the problem is quickly identified and therefore resolved.

Remote control of operations

The remote control of operations reduces the on-site intervention. As a consequence, the intervention costs are reduced. Moreover, the maintenance team is safer as they less often need to go on the sites along the tracks.

Proven reliability

Replacing signaling equipment is very expensive and can’t be done frequently. The reliability of this solution has been proven through the years as there were few replacements.

Reliable and long-lasting partnership

The collaboration between this major actor in European Railway and Alpha Innovations started many years ago. Through the years, the solution was upgraded to evolve with the customers changing needs.

The existing UCC was also customized according to the specific needs of the railway/subway industry. The hardware was adapted to withstand harsh environmental conditions (e.g. exposure to temperature fluctuation, moisture) and provided with the new Compas software card.

This partnership is long-lasting and evolutive. On-time deliveries, easy and direct contact, availability of the teams and mutual trust make this collaboration a success.

Reactivity saves lives!

After shortages of artificial respirators, hospitals are now facing a new crisis: the lack of dialysis machines and supplies. Indeed, doctors are seeing in COVID-19 patients a new syndrome: their blood does not coagulate like it should and often tends to overclot. To treat this, hospitals have a much larger need for dialysis equipment, given that both patients who needed dialysis before the pandemic as well as COVID-19 patients need this specific treatment.

That’s where Alpha Innovations comes in. We provide power supply units to a major actor in the medical sector for dialysis machines. Due to the urgent need of new equipment, our customer has asked us for help to support them in supplying hundreds of additional unforecasted power supply units in a very short period of time, to equip hospitals all around the world with new dialysis equipment to face this sudden demand. And save lives.

Thanks to our reactivity and to the flexibility of our teams (that didn’t hesitate to work around the clock, weekends included), we successfully reached the target: in less than 60 days, we were able to manufacture and deliver the first batch of additional unplanned power supply units to our customer and the full additional request will be completed in the following weeks.

Reactivity, Flexibility and Trust are the main ingredients that enabled Alpha Innovations to contribute in saving lives!

How the CE+T Group can help you manage your energy consumption?

Today, companies have multiple ways of producing their own energy. Their consumption varies and sometimes, they have a huge amount of energy left. This energy can be sold to energy suppliers. However, the price at which this energy is sold varies day by day, hour after hour.

That’s where the CE+T Group comes in: with a collaboration between the entities of the Group, we offer solutions that help you manage your energy consumption.

How do we do it?

By combining the knowledge and experience of CE+T Energrid in energy management, Alpha Innovations in monitoring solutions and CE+T Power in manufacturing of innovative converters.

  • Solutions for renewable energy

We offer 3 technology platforms, each based on innovative converters with 3 bidirectional ports. With one single module, you can connect anything!


Regarding energy transition, we can introduce new features for energy management such as:

  • Peak shavings (to reduce costs)
  • Increase in self-consumption (with storage solutions)
  • Response to demand (to shift consumption over time)
  • Pure power supply (no voltage drops, sag or surge)
  • MPPT


  • Monitoring

Alpha Innovations has years of experience in monitoring solutions. Among them, the Universal Compas Controller (UCC). The UCC communicates with the servers of the energy suppliers to define the quantity of energy that is required on their networks. This information is translated into electrical signals that are then used to control the sources and the loads.



  • Power backup solutions

The innovative solutions developed by CE+T Power are used for power backup but also for energy management. The features and high reliability of the modules bring an added value to our customers.


What are the key advantages of our innovative solutions?

  • Customization

If you have specific requirements, we can take them into account by developing custom modules and monitoring solutions. We have teams of engineers in each entity who work together to design, build and manufacture the solutions that best meet our customers’ needs. Moreover, depending on the situation, the UCC can easily be reconfigured.

  • Grid Stability

Our solutions help stabilize the grid. By communicating with the energy supplier, you can help balance production and consumption on the network. That’s what the UCC does. Moreover, the power supply solutions have features that also help with grid stability such as demand response and an increase in self-consumption.

  • Cybersecurity

Our solutions imply a constant communication with servers, it is therefore crucial for them to be protected from cyberattacks, which is a tangible concern for all our customers. Thanks to our monitoring solutions, all communication can be encrypted using TLS. Moreover, our UCC supports a wide variety of highly reliable protocols.


For which applications?

Our solutions can be used in all applications where energy optimization is important. For example, they can be useful in small power plants that use renewable energy, co-generation or biomass. Another example of application is in the railway sector where power hubs are required in remote areas. In the telecom sector, as small losses are multiplied by thousands of systems, our solutions provide smarter energy management.
