INDUCTION HEATING DEVICE, CONTROL METHOD FOR INDUCTION HEATING DEVICE, AND CONTROL PROGRAM

WIPO Patent Application WO/2012/127730

A1

The present invention comprises the following: a plurality of closely-positioned induction heating coils (11, 12, 13); capacitors (21, 22, 23) respectively connected in series to the induction heating coils; a plurality of power inverters (30, 35, 31) that apply to the serial resonance circuits of each of the induction heating coils and capacitors a high-frequency voltage converted from a direct voltage; and a control circuit (50) that synchronizes the plurality of power inverters to the same frequency and current, controls to the minimum level the potential difference between the high frequency voltage generated by a specific power inverter that supplies maximum power to the plurality of induction heating coils and the resonance current flowing through the serial resonance circuits, and sets the direct-current power supply voltage (Vdc) applied to the plurality of power inverters to a voltage such that the output voltage (Vinv) from the power inverters exceeds the mutual induction voltage (Vm).
