Abstract
Nowadays, the induction heating market is continuously growing due to its benefits including precise output power control, reduced heating times, and cleanness. The domestic induction heating application, based on the same principle, includes some extra features such as the controlled temperature profiles or over-temperature detection for an outstanding cooking process. Because of the high power density and the reduced cooling capabilities, efficiency becomes critical in this application. This paper introduces some techniques to improve the efficiency of the induction heating power converters. The proposed converters are analyzed, including the main losses sources, proving that the proposed solution improves the overall efficiency while the component count and cost are keep to reasonable values.
