Title:
POWER SUPPLY DEVICE, CONTROL DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2016/199334
Kind Code:
A1
Abstract:
In the present invention, a power supply device is provided with a switch unit, a resonant circuit, a transformer, a rectifier, and a control unit. The switch unit is a half-bridge switch unit. The resonant circuit is connected to the switch unit. The transformer is configured so as to convert output voltage of the resonant circuit. The rectifier is configured so as to rectify a signal from the transformer. The control unit is configured so as to control operation of the switch unit on the basis of an error signal based on the output voltage of the rectifier and resonant current in the resonant circuit.
