Modeling and Efficiency Analysis of LCC-S Inductive Power Transmission (IPT) system

Abstract

This paper analyzed the factors affecting the transmission efficiency of IPT system based on LCC-S compensation topology. By modeling LCC-S compensation networks, the condition of input impedance as resistive load is derived and the frequency characteristics of input impedance have been analyzed. And the frequency working range to improve the efficiency of the system have been also derived. The input and output characteristics of LCC-S compensation are further studied, and the effect of parameters on regulating the transmission power of IPT system have been verified, which provide an idea for the parameter design of IPT system compensation network.
