Three-load Cyclic Controlled Single-Stage AC-AC Resonant Converter for Induction Cooking Applications

Abstract

This paper presents single-stage AC-AC resonant converter for three load induction cooking (IC) applications. The proposed work features power factor correction, boost operation and independent power control of loads. In this work cyclic control technique is used for independent power control. Three legs of the inverter are used to power three loads. Number of switching devices per load is two. ZVS operation is achieved for load variation of wider range and high converter is obtained. The developed approach has fewer components and uses one leg per load on average. It may also be expanded to accommodate more than three loads.
