Abstract A practical method to design the heat dissipation system of the inverter is presented. By considering the effect of junction temperature on the losses, the conducting losses and the switching losses of the IGBT module used in the inverter are calculated. A heat resistance equivalent circuit of the heat dissipation system is presented; a practical formula to calculate the heat resistance of heat dissipation system is obtained, and the temperature calculation formulas of the IGBT module and heat dissipation system is derived. A heat dissipation system for the inverter using forced-air-cool is designed. The measured losses and temperatures are given, the calculated results and the experiment results verify the validity and practicability of the presented design method of heat dissipation system.
