Induction cooking application with multiple loads powered by suitable power converters and appropriate control technique needs attention. This study proposes dual frequency operated full‐bridge inverter for multiple‐load induction cooking. This inverter simultaneously powers two series resonant circuits. Each series resonant circuit is for one induction cooking load. This technique provides constant switching frequency operation for individual loads with asymmetrical duty cycle control. Output power of each load is independently controlled. The proposed inverter configuration and control technique is simulated and experimentally tested for two loads. Simulation and experimental results are in good agreement. This technique can be extended to more than two loads.
