ABSTRACT

This paper presents the analysis and design of a new ac–acresonant 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 proposed converter can operate with zero-voltage switching during both switch-on and 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. The generation of harmonics at the output will create alternating change in the magnetic flux through the inductor coil below the plates and resulting in more production of eddy currents which gives efficient performance.
