Abstract
A power supply to provide multiple synchronous outputs includes a standby power system to receive input power and regulate to become standby power and a main power system to receive the input power and regulate to become main output power. The main power system has a rectification output unit to deliver the main output power. The power supply further has at least one delay trigger unit to receive the main output power and a voltage regulation output unit. The delay trigger unit sets a voltage judgment level and determines whether to output a trigger signal based on the main output power being greater or smaller than the voltage judgment level. The voltage regulation output unit can be activated by getting the standby power. According to the generation time series of the trigger signal, the time series to generate the secondary output power can be regulated.
