Wireless Charging System With a Non-conventional Compensation Topology for Electric Vehicles and Other Applications

Abstract

The proposed paper presents a complete 500W, universal input, wireless electric vehicle battery charging system using a non- conventional compensation topology, LSPS. An algorithm to compensate Loosely Coupled Inductive Power Transfer (LCIPT) systems with such topology is explained. The design and implementation of each power converter, as well as the coils manufacturing process, is briefly covered. Experimental results are shown to validate the expected system behavior.
