Abstract
A power supply, comprising a boost converter which provides voltage to a first load, and a flyback converter which provides voltage to a second load and which utilizes an inductive element of the boost converter as a primary winding of a transformer of the flyback converter. Also, a power supply comprising a MOSFET which is disposed between solid state elements and a second reference potential and which controls current flowing through the solid state elements. Also, a circuit comprising a transformer, a first circuit portion comprising the primary winding of the transformer and a second circuit portion comprising the secondary winding of the transformer. Also, a power supply comprising means for using a common transformer for providing a boost converter and a flyback converter. Also, a power supply comprising a transformer, means for providing a boost converter utilizing the transformer, and means for providing a flyback converter utilizing the transformer.
