Abstract

A power converter provides regulated dual outputs. The power converter includes a transformer having a primary winding, and first and second secondary windings. On a primary side of the converter, there is provided the primary winding of the transformer, and a first switch having an activation terminal, where the switch is coupled to the primary winding. A first controller has its input connected to the first output terminal of the converter and its output connected to the activation terminal of the switch. On a secondary side of the converter, there is provided first and second secondary sections. The first section includes the first secondary winding and a first inductor coupled between the first secondary winding and the first output terminal. The second section includes the second secondary winding and a second inductor coupled between the second secondary winding and the second output terminal. The first and second inductors may be magnetically coupled or independent. The second secondary section also includes a second switch adapted to apply a regulating voltage to the second inductor during a regulating period of the converter. The regulating voltage increases the volt-seconds applied to the second inductor to regulate the voltage at the second output terminal.
