Abstract:
A power supply includes a first power converter, a second power converter, and a clamp reset circuit. The clamp reset circuit is electrically coupled to other components within the first power converter and the second power converter. A clamp standby connection can be provided to electrically couple the clamp reset circuit to components comprising the second power converter. The clamp reset circuit is coupled to reduce magnetizing energy of a transformer of the first power converter and limit voltage in a component of the second power converter. The clamp reset circuit may include a Zener diode and a resistor that are adapted to reduce magnetizing energy of the first power converter and voltage through the second power converter. The clamp reset circuit normally includes a capacitor that is adapted to store energy from the first power converter and the second power converter.
