Power electronics and machines infrastructure

In our power electronics and machines test lab, we test stationary and automotive power electronics modules, subsystems and converters and electrical machines.

Additionally, we test on- and off-board charging infrastructure and plug-in electric vehicles. For this, we use our vehicle (charging) test rigs, vehicle and charging emulators and all standardized communication protocols. Our bidirectional testers are suitable for grid-to-vehicle and vehicle-to-grid operation.

We have a fully equipped (power, control, data management, cooling) in-wheel-motor test rig connected to a load machine (motor-generator setup), with the capability and plans to extend it to a full vehicle synchronized multi-actuator in-wheel motors test bed.
