- To solve the problem of the high temperature of the power driver circuit of BLDCM(Brushless DC Motor) which causes by the tardy heat dissipation, the thermal numerical model was built. The simulation results indicate that the thermal field distribution of the three-phase bridge power driver circuit is relative to the power loss of IGBT(Insulated Gate Bipolar Translator), the distance between heater element and the velocity of air-cooled. By considering the effect factors, the changing curves of max-temperature points are obtained. The researches above could supply the theoretical foundation for optimizing the cooling system design of power driver circuit.
