Document Type and Number:
WIPO Patent Application WO/2023/040550
Kind Code:
A1
Abstract:
A power supply apparatus. The power supply apparatus comprises a control circuit (101) and a voltage conversion circuit (102). The voltage conversion circuit (102) is used for performing voltage conversion processing on a voltage outputted by a voltage output circuit (103), and supplying power to the control circuit (101) by using the voltage that has been subjected to voltage conversion processing, wherein the voltage output circuit (103) is used for outputting a voltage to the voltage conversion circuit (102). The control circuit (101) is used for controlling the turning on and off of a synchronous rectification switch circuit (104), wherein the synchronous rectification switch circuit (104) is used for performing synchronous rectification processing on the voltage outputted by the voltage output circuit (103).
