  • Patent number: 9433037
    Abstract: A conventional induction heating cooker which operates two inverters at the same time, with only one input current detecting circuit provided, cannot measure each of input currents to each of the plurality of inverters, and cannot control input powers by feedback control on input currents. In the induction heating cooker which has a plurality of inverters, when the input power varies to the inverter which has less input power supplied, the variation hardly influences the cooking. The induction heating cooker according to the present invention fixes the operating frequency for the inverter which has less input power supplied and performs the feedback control of the input current for the inverter which has bigger input power supplied.
