A new ZVS two-output series-resonant inverter for induction cookers obtained by a synthesis method

Multiple-burner induction cookers are suitable for using multiple-output inverters. Some state-of-the-art techniques use several single-output inverters or a single-output inverter multiplexing the loads along the time periodically. A state-space model proposed for switched converters is applied here as a synthesis tool for generating a two-output inverter. By specifying a two-output series-resonant high-frequency inverter, a new inverter for induction cookers is obtained fulfilling the requirements. The synthesized converter allows the control of the two outputs, simultaneously and independently, up to their rated powers saving component count compared with the two-converter solution
