Field Oriented Control of Traction PMSM Drive Using WBG Devices for EV Application

This paper presents a study on the field-oriented control (FOC) technique to control a traction permanent magnet synchronous motor (PMSM) drive for electric vehicle (EV) application, using wide band gap (WBG) devices. The FOC method is implemented to control the PMSM drive, which includes the PMSM motor and the SiC-inverter. The use of WBG devices in the inverter provides advantages such as highpower density, compact size, high switching operation and improved efficiency. The study includes simulation results of the FOC method, which shows improved dynamic response and reduced losses. To examine the robust performance of the system the EV traction motor is subjected to operate in three driving modes of vehicle i.e, acceleration, cruising, deceleration and in dynamic mode under off load and loaded condition. The overall functionality of the model under steady state and dynamic mode is simulated and verified in MATLAB-Simulink. Overall, the study shows the potential of using WBG devices in PMSM drives for EV applications to achieve improved performance and efficiency.
