ABSTRACT:
A power supply apparatus includes: a transformer which converts input power supplied to a primary winding to be induced to a secondary winding; a current detector which detects an output current of the secondary winding of the transformer; a voltage detector which detects an output voltage of the secondary winding of the transformer; a switch which adjusts the output voltage outputted by the transformer; and a controller which controls the switch to maintain output power obtained by multiplying the output current by output voltage, within a predetermined level.
