<p>A multiple output switching power source apparatus includes first and second transformers each having a primary winding, a first secondary winding, and a second secondary winding; a first control circuit adjusting a time for applying a DC voltage to the primary winding of the first transformer; a first rectifying-smoothing circuit rectifying and smoothing a voltage generated at the first secondary winding of the first transformer and providing a first output voltage; a second control circuit adjusting a time for applying the DC voltage to the primary winding of the second transformer; a second rectifying-smoothing circuit rectifying and smoothing a voltage generated at the first secondary winding of the second transformer and providing a second output voltage; and a third rectifying-smoothing circuit rectifying and smoothing a voltage across a series winding having the second secondary windings of the first and second transformers and providing a third output voltage.</p> |
