A Multistep Bidirectional Onboard Charger for Light Electric Vehicles Using Interleaved Luo Converter
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.
