Abstract
An AC/DC converter includes a rectifier circuit, at least one restraining unit, and a power interruption detection circuit. The rectifier circuit is used for converting an AC (alternating current) to a DC (direct current) power source. The restraining unit is connected to an output terminal of the AC power supply. The restraining unit includes a resistor and a switch connected in parallel. The power interruption detection circuit detects whether an input power cycle is regular. When the input power cycle is interruptive, a signal is generated to change a state of the switch in the restraining unit to make the resistor of the interfere in the circuit to restrain an inrush current in any operational circumstance, such as warm startup or quick startup.
