CONTROL UNIT OF INDUCTION HEATING UNIT, INDUCTION HEATING SYSTEM, AND METHOD OF CONTROLLING INDUCTION HEATING UNIT |
摘要 |
A control unit of an induction heating unit controls AC power output to a heating coil of a transverse type induction heating unit that allows an alternating magnetic field to intersect a sheet surface of a conductive sheet that is being conveyed to inductively heat the conductive sheet. The control unit includes: a magnetic energy recovery switch that outputs AC power to the heating coil; a frequency setting unit that sets an output frequency in response to at least one of the relative permeability, resistivity, and sheet thickness of the conductive sheet; and a gate control unit that controls a switching operation of the magnetic energy recovery switch on the basis of the output frequency set by the frequency setting unit. |

1. A method of controlling an induction heating unit by controlling an AC power, which is output to a heating coil of a transverse type induction heating unit allowing an alternating magnetic field to intersect a sheet surface of a conductive sheet which is being conveyed to inductively heat the conductive sheet, the method comprising:
outputting the AC power to the heating coil by a magnetic energy recovery switch; setting an output frequency in response to at least one of a relative permeability, a resistivity, and a sheet thickness of the conductive sheet; and controlling a switching operation of the magnetic energy recovery switch on the basis of the output frequency which is set. |
