ABSTRACT:
A power supply with surge voltage control functions. The power supply has a rectifying unit rectifying a voltage of an AC power source externally applied; a fuse resistor inputting and applying the AC power source to the rectifying unit, and cutting off the voltage of the AC power source exceeding a predetermined value; a pulse generation unit driven by an output voltage of the rectifying unit, and generating a pulse having a predetermined period; a transformer driven by the pulse, and inducing a predetermined ac voltage; and a surge voltage control unit turning on by an ac voltage induced by the transformer to form a current path between the AC power source and the rectification unit, wherein the current path is formed between the AC power source and the rectifying unit via the fuse resistor when the output voltage of the rectifying unit exceeds a predetermined value.
