Power loss calculation and thermal modelling for a three phase

الملخص EN

Power losses calculation and thermal modelling for a three-phase inverter power system is presented in this paper.

Aiming a long real time thermal simulation, an 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.

The proposed model can provide accurate power losses with a large simulation time-step and suitable for a long real time thermal simulation for a three phase inverter drive system for hybrid vehicle applications.
