Field Oriented Control of PV-BESS Fed Traction PMSM Drive for EV Application

This paper presents a study to design a novel electric power-drivetrain for Solar PV-BESS powered EV’s driven by traction permanent magnet synchronous motor (PMSM) for an automobile application. The proposed field-oriented control (FOC) technique for controlling the traction motor aims to improve dynamic and steady state performance of drive system. For maximum power extraction from PV array IN-C MPPT algorithm is used in the model. The key features like higher efficiency of drive system, longer battery life, faster dynamic response, long range are considered in this paper. The traction system is supported with the BESS connected in shunt to maintain constant DC link bus voltage. The drive system is subjected to operate in three driving modes i.e., acceleration, cruising (constant speed) and deceleration mode along with variable solar insolation condition to test the robustness behavior of system. The simulation results of model are verified in MATLAB-Simulink environment.
