Abstract :
In this work an object-oriented traction drive model utilizing an averaged inverter model together with models of the electric machine and the drive control system is presented. The inverter model is used for loss calculation and is applicable for continuous and discontinuous modulation strategies. With the proposed model inverter losses and junction temperatures can be calculated together with electrical and mechanical quantities of the machine in one simulation. Therefore, the proposed model can be used to identify the most efficient modulation strategy for each operation point in traction drive inverters.
