Abstract:
1. A power supply comprising: a first power converter adapted to convert an input to a first voltage output, the first power converter including a first transformer having a first primary winding; a second power converter adapted to convert the input to a second voltage output, the second power converter including a second transformer having a second primary winding that is not the first primary winding of the first transformer, wherein the first voltage output is separate from the second voltage output; and a shared clamp reset circuit coupled to the first primary winding of the first transformer and coupled to the second primary winding of the second transformer, wherein the clamp reset circuit is adapted to manage leakage inductance energy within the first transformer and within the second transformer 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.
