Analysis and optimal design of induction heating cookers

Abstract

This paper deals with the optimal design of induction heating cooker starting from the analytical analysis of the cooker model. The analytical analysis method is based on the construction of the equivalent circuit of the cooker in which the circuit parameters are calculated from the geometries in a very simple way. By using the analysis method of equivalent circuit, the numerous combinations of primary winding coils for the specific rated power are obtained in fast computation time for a given secondary conductor. Through the calculation procedures, the optimal number of turns and their optimal positions can be obtained with which the cooker provides the highest efficiency at the rated power. The effectiveness and accuracy of the proposed analysis and design are verified through finite element analysis for practical and designed models.
