Design And Control of Solar-Battery Fed PMSM Drive For LEVs

This paper deals with a novel power-drivetrain design of Solar PV-battery powered LEV's driven by Permanent Magnet Synchronous Motor (PMSM) along with the motor controller for an automobile application. In this paper mathematical modelling of Electric Vehicle and PMSM motor are done to have the in-depth analysis of performance of vehicle. To harness maximum power from PV array INC MPPT algorithm is used in the model. High efficiency, low cost, extended battery life, smooth torque and improved range, are the main key features considered in this paper. Along with the Solar PV array the LEV is supported with the battery which is connected in shunt to maintain constant voltage across the VSI. To test the robustness of the system the EV motor is operated in three modes i.e acceleration, constant speed and deceleration along with variable solar insolation condition. The functionality of system under dynamic and steady state condition is simulated and verified in MATLAB-Simulink environment.
