Testing services: o AC-DC and DC-DC power converters ; o Converter subassemblies (submodules, inverters, rectifiers) ; o Converter components (power modules, capacitors, controls, cooling).
Consulting services: o Converter test bench development ; o Consulting services for power converter testing and validation.
Laboratory & Equipment description
The test-bench is designed to carry out tests in a back-to-back configuration. For this, two converter prototypes are required.
The shielded laboratory, a Faraday cage, is equipped with filtered power supply and fiber optic controls. It can accept prototypes that require the supply up to 7,5kV and 100 kW power dissipation and can combine the following three cooling methods: 100kW water cooling, 20 kW forced air and 20kW natural convection. The controls is done via Matlab/Simulink CPU, FPGA code generation and a Speedgoat real time target. The test bench is equipped with a resilient integrated safety interlock.
Voltage: up to 50kVac and 75 kVdc
Power: up to 10MW in back-to-back
Size: 5x5x3m, 1 cubic meter max single object
Cooling: water, natural or forced convection
EMC shielding: 100dB, 10kHz – 10GHz
Safety: integrated interlock system
Introducing the new concepts of high voltage and high power converters implies multiple mandatory validation steps prior to industrialization. Most commonly, these are the steps performed:
off-line simulation ;
real-time simulation including Hardware-in-the-Loop testing (HIL) ;
small scale mock-up with Power Hardware-in-the-Loop testing (PHIL) ;
prototype testing on a power test bench ;
demonstrator testing in the real environment.
The power converter platform allows for the validation of different converter topologies ensuring the TRL5, as well as to extend the validation of converter components (subassemblies, power modules, capacitors, controls, cooling, …) up to the TRL6.
The power converter platform is suitable for testing of DC-DC and AC-DC power converters for the following applications:
