Abstract
An IH cooking heater should have high efficiency heating and accept all metal pans. In order to develop the high efficiency induction heater for all metals, it is necessary to analyze magnetic characteristics of the working coil of IH cooking heater. However such an analysis has not been discussed until now. This paper presents a magnetic analysis for high efficiency induction heating, which can heat not only iron pans but also aluminum pans. The heating performance of IH cooking heater which heats both iron and aluminum pans is discussed with the analysis result of magnetic flux and eddy current distribution.
