Abstract: In a power supply apparatus having voltage doubler rectifier circuit (5) connected to secondary winding (1B) of transformer (1), diode (13) is connected between transistor (3) and primary winding (1A) of transformer (1). By detecting an AC voltage at a junction point between primary winding (1A) of transformer (1) and diode (13) thereby performing over-voltage protection, the difference between the maximum operating voltage and the no-load operating voltage is decreased and the voltage during no-load operation is lowered and thus small-sized power supply apparatus and peripheral equipment can be provided.
