Patent ID: 8279636

Claim:
A power supply comprising: a first power converter adapted to convert an input to a first output; a clamp reset circuit coupled to a first primary winding of a first transformer included in the first power converter, wherein the clamp reset circuit is adapted to reduce magnetizing energy in the first transformer of the first power converter, wherein the clamp reset circuit further comprises: a capacitor, wherein the capacitor is adapted to store energy received from the first power converter and the second power converter; and a Zener diode coupled to the capacitor, wherein the Zener diode is adapted to prevent the energy received from the first power converter and the second power converter to exceed a threshold, wherein the Zener diode limits voltage on the capacitor; and a second power converter coupled to the clamp reset circuit and adapted to convert the input to a second output, wherein the clamp reset circuit is further coupled to a second primary winding of a second transformer included in the second power converter and adapted to limit voltage on a component of the second power converter.
