要約(英語): An induction heating system is proposed as a new circuit topology for induction heating cookers that can be used with all metals. This system has the mechanism to drive an IGBT and a MOSFET in parallel that switch the inverter between full-bridge or modified half-bridge configuration according to the cookware material. When cookware made of a low-resistivity material such as copper or aluminum is heated, the inverter is switched to the half-bridge configuration, which turns off the IGBT leg earlier than the MOSFET leg. When cookware made of a high-resistivity material such as iron or magnetic stainless steel is heated, the inverter is switched to the full-bridge configuration. We confirmed a turn-off timing for the IGBT where the loss of the switching element in the parallel drive was minimized by an experiment. The proposed inverter effectively improved the electricity conversion efficiency for all metals pan heating with the utilized IGBT and MOSFET legs.
