A Novel power losses calculation method and thermal simulation model for a three-phase inverter power module (IPM) paper. In this model, an inverter drive system simulation model with the aim of fast and efficient power loss and thermal analysis for inverter power devices in electrical vehicle applications is presented. Aiming a long real time thermal simulation, a accurate average power losses calculation based on PWM reconstruction technique is proposed. For carrying out the thermal simulation, a compact thermal model for a three-phase inverter power module is built. The thermal interference of adjacent heat sources is analysed using 3D thermal simulation. This approach has a very fast simulation speed and produces the voltages and currents associated with each of the semiconductor switches in real-time by using PWM reconstruction. The proposed model can provide accurate power losses with a large simulation time-step and suitable for a long real time thermal simulation for inverter power modules.
