  • Publication number: 20150108118
    Abstract: [Object] An object is to provide an induction heating method having a high power factor in which when thermal processing is performed through a plurality of heating coils receiving the supply of the current to generate mutual induction, it is possible to easily and rapidly perform synchronization control on a coil current and in which when the current is varied, even if the speed of control on the current value is increased, this little affects an inverter phase angle. [Solving means] In an induction heating method using an induction heating device that heats an item to be heated and includes a plurality of self-resonant circuits to which a resonant high-frequency power supply feeding currents of equal frequency to a plurality of heating coils receiving the supply of the current to generate mutual induction is connected, the phases of impedances within a system are made to coincide with each other to minimize the phases.
