Abstract

The design and implementation of a high-efficiency nonisolated single-stage on-board battery charger (OBC) for electric vehicles are presented. Reviewing the conventional topologies, a suitable circuit structure is determined to charge a battery in a wide spectrum of input and output conditions. Additionally, a suitable strategy for a highly efficient OBC is presented through the analysis of selected topology. A detailed theoretical analysis, operating strategy, and experimental results on a 3.7-kW prototype are presented in order to evaluate the performance of the proposed system.
