Abstract
A multi-output power supply includes: a switching element that turns ON and OFF currents flowing through all primary coils of a plurality of transformers connected in parallel at a same time; a plurality of output circuits that rectify and smooth voltages induced in secondary coils of the plurality of transformers to produce a plurality of output voltages; a plurality of feedback voltage detection circuits that detect feedback voltages corresponding to the output voltages of the plurality of the output circuits; an averaging circuit that calculates an average feedback voltage from the feedback voltages detected by the feedback voltage detection circuits; and a control circuit that uses feedback control to turn the switching element ON and OFF according to the average feedback voltage calculated by the averaging circuit.
