Abstract (en)
[origin: EP2760251A1] A plurality of inverter circuits 6a to 6e that supply high-frequency power to a plurality of heating coils 16a to 16e, power detecting means 14a to 14e for detecting power output from the inverter circuits 6a to 6e to the heating coils 16a to 16e or power input to the inverter circuits 6a to 6e, output current detecting means 12a to 12e that detect output currents of the inverter circuits 6a to 6e, and load resistance detecting means 20 that perform load detection using results of detection of the power detecting means 14a to 14e and the output current detecting means 14a to 14e are provided. Every time heating power setting is changed, control means 19 performs, by the load resistance detecting means 20, load detection by separately and individually allowing the heating coils or inverter circuits to be in an individual conduction states. The control means 19 sets power distribution for each of the heating coils 16a to 16e or each of the inverter circuits 6a to 6e, on the basis of the result of load detection.
