Add to ORKGPartial discharge (PD) is a key degradation mechanism of insulating materials such as ceramics in power modules. Among others, this is due to high voltages under operation of the modules. PD is due to high electric field strengths in the vicinity of the edge of the metallization of the insulating substrate e.g. direct copper bond (DCB). This paper focusses on the encapsulating fluid or gel that influences the partial discharge inception voltage (PDIV) due to its electrical properties. Simulations of the electric field strength were carried out to analyze the effect of the permittivity of the covering fluid. The simulations show a reduction of the electric field strength at the edge of the metallization with increasing relative permittivity....
