Improved FOC of IPMSM using model predictive current control decreasing switching loss for EV

The control method of IPMSM (Interior Permanent Magnet Synchronous Motor) can be classified DTC (Direct Torque Control) and FOC (Field Oriented Control). For EV application using IPMSM, the improvement of transient states dynamic and switching loss reduction are also required, as well as stable current quality in steady states. Also, the switching loss of VSI in EV power train is very important issue in terms of the maximum possible travel distance of EV corresponding to the battery capacity. Therefore, in this paper, improved FOC of IPMSM using model predictive current control decreasing switching loss for EV. Simulation results are presented to verify the proposed method decreasing switching loss.
