Dual-Sided L-C-C Compensated Wipt Application for Electric Vehicle Battery Charging System

Abstract

This study examines the compatibility of wireless chargers using the dual-sided LCC compensation topology and those using the four fundamental compensation topologies for wireless inductive power transfer systems (WIPT). To provide  analysis of dual-sided LCC  topology. Main criteria of paper is design considerations for various compensation topologies: (1) secondary sides with series and parallel when using an LCC compensation topology as the primary side; (2) primary sides with series and parallel when using an LCC compensation topology as the secondary side. LCC-S, LCC-P, S-LCC, and P-LCC are  four topologies that will be discussed. Verified  the analysis with MATLAB/SIMULINK. Even with a 265mm misalignment at 300mm gap, the current-fed DC-DC converter topology has a 95.8% efficiency.
