Course work and exam formalities
The course work consits of five experiments, the analysis of the collected data and the preparation of a readable test reports for each experiment.
The exam consists of:
- Oral qualification test for each experiment (pass)
- Written exam at the end of the laboratory course (50%)
- Written reports for five experiments (50%)
Description
Electrical and thermal characterization of power semiconductor devices like Power MOSFET, IGBT, PIN-diode.
Following experiments will be available:
- electrical characteristics in a quasi-static mode
- electrical characteristis in a pulsed mode
- gate charge curve
- avalanche ruggedness (UIS)
- thermal safe operating area
- switching behavioour (double-pulse method)
- thermal resistance of materials
- transient thermal resistance of MOSFET-devices
