N2 - The blocking voltage of silicon carbide (SiC) devices is higher than 10 kV, and the temperature resistance is higher than 200 °C. High voltage can cause high electric stress inside power modules. Increasing the insulation ability of the encapsulation material of SiC power module becomes an urgent requirement. The electrical field-dependent permittivity (FDP) material can be used to release the high electric stress. In this paper, by preparing the FDP composite material composed of silicone gel and barium titanate, the relationships between the permittivity and frequency of the material at different temperatures are studied. By analyzing the dielectric properties of the composite material under high temperature and high voltage, the advantages and disadvantages of using FDP material to reduce the electric field stress in power module are investigated.
