Abstract
In this paper, primary LCC compensation topology and their variants are firstly investigated to adapt sub-harmonic control so that the wireless power transfer system can achieve the advantageous of soft switching, inherent open-circuit protection, high design freedom and high efficiency, simultaneously. Extensive comparisons are conducted among the conventional LCC compensation topology and its variants, namely LCCC compensation topology, LLCC compensation topology, and LCLCC compensation topology. The characteristics of these topologies are analyzed based on the perspective of input admittance. The experimental results illustrate that the variants achieve an almost 50% reduction in the peak-to-peak magnitude of inverter current, and a maximum efficiency enhancement of up to 5.9% when contrasted with the conventional LCC topology.
