Abstract: An induction heating device according to the present invention includes: an induction heating coil 10 with a conductor 100 wound around a predetermined axis line AL; a member 11 including at least one soft magnetic material 110, the at least one soft magnetic material 110 being disposed at or on an outer side of each of axial end portions 102 of the induction heating coil 10 in an extending direction of the axis line AL; and a heating object 2 disposed on an inner side of the induction heating coil 10 and the member 11, the heating object 2 being configured to be heatable by induction heating using a magnetic flux from the induction heating coil 10.

Abstract: A control method, a controller, and a control system including a converter and the controller are provided to improve load responsiveness of control by the converter. The converter has a primary circuit that includes a voltage generation circuit for generating a square wave and a resonant circuit for converting a waveform of the generated square wave, and a secondary circuit that is electromagnetically coupled to the primary circuit and that generates an induced electromotive force. The controller controls the voltage generation circuit by a control target power factor. To implement power factor-based control, the controller controls the voltage generation circuit, based on a derived power factor derived from an active power and an apparent power relevant to the resonant circuit in the primary circuit or a derived power factor derived from a phase of the primary circuit.
