Summary This paper presents a single‐stage AC–AC resonant converter configuration for different material vessel induction cooking. The proposed configuration features input power factor correction, boost operation, and integrated bridge inverter configuration for multiple loads. In this topology the inverter legs are operated at two different frequencies to power induction cooking loads of steel and aluminum vessels. The induction cooking loads are operated at frequencies closer to their respective resonant frequencies. The load powers are independently controlled by pulse frequency modulation (PFM) technique. The proposed topology eliminates the use of electromechanical switches. The proposed single‐stage AC–AC resonant converter configuration has been tested with two different vessels of steel and aluminum. The simulation and experimental results of the proposed configuration are in good agreement. This topology offers the advantages of low component count, high efficiency, and suitability for different material induction cooking.
