WP3: Ruggedness of IGBTs

Objective: To contribute towards development of robust components aiming to reduce downtime of high voltage converters. Primary focus is aimed at obtaining a stable behavior during and after fault conditions. The WP will mainly be processed by a PhD scholarship hosted by the research partner TU Chemnitz.

WP highlights (May 2017):

• PhD work on analysis of fault ruggedness of IGBTs
  • • Interim FEM simulations of effects from thickness of emitter metallization 
• Provide test equipment for short circuit experiments
  • • A 6kV double pulse short circuit tester constructed and commissioned 
• Experimental work on short circuit ruggedness
  • • Provided special test objects for ruggedness experiments
