Maximum Efficiency Point Calculation For Multiple Electric Vehicles of Wireless Power Transfer System With LCC-LCC Compensation Topology

Wireless power transfer (WPT) system has been used in electric vehicle (EV) widely. However, the maximum efficiency point of a WPT system with LCC-LCC compensation topology has not been calculated, especially in the multi-receiver WPT system. Thus, in this paper, a calculation of the maximum efficiency point has been proposed for the multi-receiver WPT system with LCC-LCC compensation topology. The theoretical results are verified in the simulation model, which can be used to guide the design of the impedance converter at EVs of the WPT system.
