Abstract
This paper presents a novel permanent-magnet synchronous motor (PMSM) drive system with bidirectional Z-Source inverter (ZSI) for electric vehicles, and a modified vector controlled scheme of the PMSM drive is developed by considering DC-link voltage boosting. Characteristics of ZSI are used for DC-link voltage control in a single stage to obtain wide speed range of PMSM instead of field weakening control. Several simulation results obtained in Saber verify the feasibility and effectiveness of the proposed system.
