Solar Pv-Powered Srm Drive by Using Tri-Port Converter for Electric Vehicles

Abstract

In this paper Hybrid Electric vehicle (HEV) technology provides an effective solution  for  achieving  higher  fuel  economy  and  better  performances  with reduced greenhouse gas emissions. In order to extend the EVs’ driving miles, the use of photovoltaic (PV) panels on the vehicle helps decrease the reliance on vehicle batteries. Based on phase winding characteristics of SRMs, a tri-port converter is proposed in this paper to control the energy flow between the PV panel battery and SRM. Six operating modes are presented, four of which are developed for driving and two for standstill on-board charging. In the driving modes, the energy decoupling control for maximum power point tracking (MPPT) of the PV panel and speed control of the SRM are realized. In the standstill charging modes, a grid-connected charging topology is developed without a need for external hardware. When the PV panel directly charges the battery, a multi-section charging control strategy is used to optimize energy utilization. Simulation results based on Matlab/Simulink prove the effectiveness of the proposed tri-port converter, which has potential economic implications to improve the market acceptance of EVs
