Design and Optimization of GaN-HEMT Based Inverter-Coil Integrated Module for Flexible Cooking Surface Induction Cooktop

In this paper, the optimal design guidelines for flexible cooking surface (FCS) induction cooktop is proposed taking into account inverter-coil integrated induction heating (IH) module. In order to improve the heating performance of FCS IH system, the working coil shape and resonant network should be optimally designed. Through simulation and comparison and analysis results, working coil and the resonant network are designed. The validity of design guideline proposed for FCS IH system is verified through experimental results.
