Abstract:
Disclosed is a power supply and a power supply system using such power supply. The inventive power supply includes a power converter for converting an input voltage into an intermediate output voltage, an output protection circuit connected to an output terminal of the power converter and an output terminal of the power supply for protecting the power converter by its ON/OFF operations, and a control unit connected to the output protection circuit for controlling the output protection circuit. When an operating frequency of the power converter is higher than a first reference frequency and the intermediate output voltage is higher than a first reference voltage, the control unit outputs a first control signal to a control terminal of the output protection circuit to turn off the output protection circuit.
