Resonant Circuit Response for Contactless Energy Transfer under Variable PWM

A. Badawi, S. A. Kazmi, R. I. Boby, M. H. Shah, and K. Matter
Abstract—This paper presents an analysis and performance simulation of series resonant medium used for energy transfer. It uses soft switching for operating the active elements, turning them on and off without major losses. Simulation results comprise of output voltage variation based on the PWM modulation from 0% ~ 100% with step size of 20% in order to exploring appropriate relationship. The major objective of this work is to obtain the highest possible response based on the set parameters of modulation and resonant frequency. The effect of Pulse Width Modulation is studied for maximum power transfer at a given resonant frequency forcing to realizing a DC-DC converter. The converter behavior deviating from the resonant frequency is also discussed. The current distribution in the primary and the secondary turns of windings varies significantly because of the massive change in magnetizing inductance. Simulation results are representative of theoretical expectations.

Index Terms—Dc-dc converter, soft switching, inverter, PWM modulation, contactless energy transfer.
