Abstract

A power control system is provided for AC mains, including an input bridge rectifier connected to the AC power mains, and a buck regulator circuit connected to the DC output of the input bridge rectifier, the output of the buck regulator circuit providing a DC power output bus. A current sensor is connected to the output of the buck regulator circuit, and one or more capacitors is connected across the DC power output bus for receiving current from the buck regulator circuit. The buck regulator circuit is controlled to limit peak output current thereof.
