Predictive Control of a New Configuration of Bidirectional Quasi Y-Source Inverter Fed IPMSM for Electric Vehicle Applications

In this paper, a new high boosting bidirectional quasi Y-source inverter (BQYSI) is designed to overcome the problems of the traditional inverters. BQYSI has advantages of continuous input current and bidirectional power flow. The proposed inverter is controlled to drive an interior permanent magnet synchronous motor (IPMSM) for electric vehicle applications. A finite control set model predictive controller (FCS-MPC) is designed to select directly the inverter switching state based on minimum torque and flux error without modulation technique. The output voltage and current of the BQYSI are controlled to determine the shoot through duty cycle. Simulation results are analyzed to evaluate the performance of the proposed strategy under motoring and regenerating operating conditions.
