In the Power Electronics Lab, we develop, investigate and optimize power electronic components and systems. An extensive infrastructure is available for this purpose.
Our offer
We offer you a wide range of tests, simulations and other services relating to power electronics.
Test range of power converters and drive systems
- Determination of efficiencies
Function tests / control of various sources and sinks - Control / regulate converter hardware without having to program the processor (PIL or RCP)
Test range of power semiconductors
- Power cycling (uni- or bidirectional)
- Cosmic ray tests with protons or neutrons
- Static, switching and thermal behavior (Rth, Zth)
- Functional and quality testing of wafers
- Humidity and climatic reliability tests
Test range of magnetic components
- Hysteresis and loss measurement (Hz to MHz)
- Inductance / frequency response
Further test and service offerings
- Terminal contacting of semiconductor components on the wirebonder
