Abstract

In this paper, a 2kW PFC active IPEM (Integrated Power Electronics Modules) employing CoolMOS and SiC diode is developed. The thermal model of IPEM is developed and the power dissipation of every power devices in the active IPEM is calculated through the measurement-based power loss graph in datasheet. With the requirements of uniform temperature distribution and slight thermal interaction between power dice, the variation of temperature gradient distribution with the heat transfer coefficient of heatsink and die position is analyzed. The thermal interaction distance of power die is investigated and the tradeoff between thermal and electrical design is considered. The analysis is verified by the simulation results.
