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.
Keywords: Resonant power conversion, inverter, induction heating
