New Compact Non-Isolated on Board Battery Charger for EVS

Limcy Cheriyan | Balachandar E

Abstract: This paper presents a non-isolated on board battery charger for electric vehicles. This replaces the battery charger with interleaved cascade buck boost converter by a cuk converter and an inverting amplifier which reduces the overall size of the system. Closed loop control provides precise control of load voltage. The proposed method uses less number of switches hence reduce the THD than the conventional method. The implementation using MATlab is also presented.
