ABSTRACT:
A multi-output power supply includes a standby power system and a main power system. The main power system has a transformer and a rectification output circuit connecting to the transformer to generate first output power. The power supply further has an output time series judgment circuit and a plurality of voltage regulation units connecting respectively to the standby power system and the rectification output circuit. The output time series judgment circuit has a preset reference potential compared with the potential of the first output power to determine whether to output a feedback signal. Each voltage regulation unit is connected to the output time series judgment circuit to receive the feedback signal and be activated normally and determine a regulation time spot to synchronously regulate the first output power to second output power. Thus the time difference for delivering the first output power and the second output power can be regulated.
