The poor power quality charging operation impacts the grid adversely. The slow unidirectional charging of light electric vehicles (LEVs) ceases the user for the limited operations. In this work, a bidirectional on-board charger (OBC) for an LEV is proposed. The bidirectional power flow operation increases the usability of the LEVs during non-commute hours. A voltage source converter is used as a front-end converter and interleaved isolated Luo (ii-Luo) converter is used as a second stage converter. The ii-Luo converter regulates the charging and discharging operation of the OBC. The power rating to design the OBC, is 2kW. For the fast charging operation, it charges a 48V battery with the 2kW power. Moreover, for slow charging operation, it charges the same battery with a 1kW power. The controllers are designed to regulate the overshoot, undershoot, and ensures the smooth operation of OBC.
