Performance Analysis of Two-Stage Charging System for Light Electric Vehicles

In this paper, a single-phase two stage on-board charging scheme for light electric vehicles (LEV s) is presented. The first phase is an AC-DC power factor correction (PFC) stage, which transforms the AC input from the utility grid into DC supply while parallel setting up the input current, and the second stage has bidirectional DC-DC converter, which enables the charging of battery during grid-to-vehicle mode of operation with desired voltage and current values. The present system is simulated in MATLAB/Simulink and real-time validation is also performed on Opal-RT platform. The results obtain through both the simulation and real-time controller indicate the effectiveness of the developed LEVs battery charger.
