Abstract: As the core components of electric drive power supply, the power inverter has high power density and more heat production, so it is important to study the thermal safety of power inverter. In this paper, based on the finite volume method, a new electric drive power inverter's thermal performance was analyzed and its thermal structure was analyzed and investigated using 3D temperature field calculation. The designed thermal structure has satisfied heat dissipation performance, which validated by the simulation results. This study provided the basic reference for the integrated design and optimization of the thermal structure of power inverter, and improved the efficiency of design.
