Systematic Approach to High Efficiency Resonant Converter used in Domestic Heating Application

Abstract

The main objective of this project is to develop the analysis and design of a new ac–ac resonant converter applied to domestic induction heating. The proposed topology, based on the half-bridge series resonant inverter, uses only two diodes to rectify the mains voltage. The switch operates in soft commutation mode and serves as a high frequency generator. switch-off transitions. Moreover, this topology doubles the output voltage, and therefore, the current in the load is reduced for the same output power. As a consequence, the converter efficiency is significantly improved. A  circuit model for AC to AC converted induc­tion heating system is also proposed
