Abstract
The purpose of the invention is to solve the problem in that the conventional switching power supply has high standby power consumption and to address possible standby power specification requirement in the future. The resonant conversion control device with very low standby power loss includes: an AC/DC conversion unit, a DC/DC conversion unit, a DC/DC conversion control unit, and a standby mode control unit. The present invention is able to effectively utilize the low switching loss feature of the resonant conversion device and use the output voltage value as a condition to determine the concept of system operating mode to control the operating status of the AC/DC conversion unit and the DC/DC conversion unit, thereby effectively reducing the power loss in standby mode.
