Converters and Power Electronics

In the market of power conversion, addressing users and manufacturers of equipment and components for power conversion SuperGrid Institute has built an offer around three main activities:
- Test of converters and characterization of components
- Design and test of medium frequency transformers
- Design and test of power converters
- Applications may be converters for power production, HVDC transmission, MVDC networks and onboard conversion in transportation where efficiency, reliability, robustness and compactness are key

Test of converters and characterization of components
To predict and increase performance of power converters, accurate models of their active components are required. For this purpose SuperGrid Institute has developed highly specialized platforms to perform characterization of active power electronics components, including:
- Static characterization of power switches
- Dynamic characterization of power switches in hard or soft commutation
- Thermal impedance measurement
- Robustness and reliability test (HTGB, HTGS, HTCMB, HTRB)
- Repetitive avalanche tests
- Repetitive short circuit test
Along with the testing, SuperGrid Institute can generate multi-physic models and characterization of soft switching mode that allows for optimization of power converter design for improved losses and lifetime.
SuperGrid Institute also offers to test entire power converters up to 10MW, 50kV AC and 75kV DC on its Power Converter Test Platform.
Design and test of medium frequency transformers
Use of Medium Frequency Transformers in power converters, allow for a very compact and highly efficient power conversion at medium voltage level, which is very important in application such as offshore wind, oil and gas, onboard conversion in transportation (rail or marine).
SuperGrid Institute has developed expertise and technologies for Medium Frequency Transformers and offers to undertake complete design of the transformer, characterize the magnetic materials and test the complete transformer in no-load, full-load and short circuit conditions.
Design and test of power converters
SuperGrid Institute has developed a work-flow for converter design, data base of components characteristics and a number of technologies that allows for design of power to client specification with optimization for high performance and small volume.
The control-command will be validated through real time simulations as Hardware In the Loop (HIL) test and through small scale mock-up with Power Hardware In the Loop (PHIL) test. After design phase, a full scale prototype of the converter can be tested on Power Converter Test Platform.
