Abstract:
1. 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; 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 manage leakage inductance energy of the second transformer of the second 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 and the Zener diode limits voltage on the capacitor.
