Method and apparatus for supplying and switching power

Abstract

A dimming power supply includes a power source, a transformer, a full bridge rectifier and a control switch.

What is claimed is: 
     
         1 . A power supply, comprising:
 a power source;   a transformer comprising a first winding and a second winding, said first winding being connected to said power source, said second winding comprising a first tap and a second tap, said first tap being connected to a first load output;   a full bridge rectifier comprising four nodes, a first of said four nodes being connected to said second tap of said second winding, a second of said four nodes being connected to a second load output, and a third of said four nodes being connected to a reference voltage source;   a control switch connected between a fourth of said four nodes and said reference voltage source; and   a current monitor connected between the control switch and the reference voltage source.
