CONTROL DEVICE FOR INDUCTION HEATING DEVICE AND METHOD FOR CONTROLLING INDUCTION HEATING SYSTEM AND INDUCTION HEATING DEVICE

摘要

A transverse type induction heating device crosses an alternating magnetic field with a plate surface of a conductive plate being threaded, thereby inductively heating the conductive plate. A control device for this induction heating device controls AC power output to a heating coil of the induction heating device and comprises: a magnetic energy regeneration bidirectional current switch for outputting AC power to the heating coil; a frequency setting device for setting an output frequency based on at least one of the permeability, resistivity, and plate thickness of the conductive plate; and a gate control device for controlling the switching operation of the magnetic energy regeneration bidirectional current switch on the basis of the output frequency set in the frequency setting device.
