Abstract:
A power supply, comprising:a first switch and a second switch to direct electric current flow through a transformer primary winding at a selected end of said transformer primary winding; a snubber capacitor connected at a first end of said snubber capacitor to said first switch and said second switch at a junction point with said selected end of said transformer primary winding; an output bus to deliver electric current, generated from discharge of said snubber capacitor, to a load; wherein said snubber capacitor charges through said first switch when said first switch is closed and said second switch is open thereby connecting a second end of said snubber capacitor to a positive input bus of said power supply, and said snubber capacitor discharges through said load when said first switch is open and said second switch is closed thereby connecting said second end of said snubber capacitor to a negative input bus of said power supply.
