Dual frequency full-bridge inverter for all metal induction heating cooking applications

Abstract

In this paper, a dual frequency full-bridge series resonant inverter topology is proposed for induction heating applications. ADC method is employed for power regulation. Each leg of the proposed full-bridge inverter operates at different frequency making it suitable for all metal induction heating applications. The proposed inverter resonates automatically for magnetic and non-magnetic vessel and thereby transferring maximum heating to the vessel. The component count is less. The detailed description, circuit analysis and simulation results of the proposed converter are presented.
