摘要： 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.
