Abstract
An example power supply includes a first power converter, a second power converter, and a shared clamp reset circuit. The first power converter is adapted to convert an input to a first output and includes a first transformer having a first primary winding. The second power converter is also adapted to convert the input to a second output and includes a second transformer having a second primary winding. The second primary winding of the second transformer is not the first primary winding of the first transformer. The shared clamp reset circuit is coupled to the first primary winding of the first transformer and is coupled to the second primary winding of the second transformer to manage leakage inductance energy within the first transformer and within the second transformer.

A power supply comprising:
- a first power converter adapted to convert an input to a first 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 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;
- 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.
