INDUCTION HEATING DEVICE HAVING AUTOMATIC APPLICATION CONTROL CIRCUIT RESPONDING TO CLOSELY ARRANGED HEATING COIL

摘要

PROBLEM TO BE SOLVED: To provide a control device for accurately automatically applying a required power value to a plurality of heating coils even when the plurality of heating coils are closely arranged, and mutual induction action is present between the coils adjacent to each other when the plurality of heating coils are arranged in one induction heating device, and a heating object must be heated in a desired heat distribution.

SOLUTION: This induction heating device is provided an automatic application control circuit for each of the plurality of arranged heating coils, and also includes means for controlling power at a required value by feeding back the mutual induction action from the respective heating coils and outputting an updated application voltage to the heating coils even when the mutual induction action due to close arrangement is present between the heating coils.
