Abstract
Power module reliability can be increased if problems due to high electric fields can be better understood. This paper proposes a global analysis using finite element simulations. Results are confirmed thanks to optical detection of partial discharge localization. Solutions to reduce field reinforcement are proposed and discussed. A discussion of maximum electric field handled by insulation gel is also provided.
