Abstract
A regulated DC power supply facilitates extended and uninterrupted power to a load by using a secondary power source such as a regenerative fuel cell that has its DC power output conditioned by a power converter. The DC power supply includes a rectifier that converts AC power from an AC power source to DC power for a load coupled to a DC bus. A fuel cell arrangement is electrically coupled to a power converter that is coupled in turn to the DC bus, the converter conditions an unconditioned DC power output of the fuel cell to the load. A system controller is communicatively coupled to the rectifier, the converter and to a fuel cell controller, the fuel cell controller initiating DC power output from the fuel cell arrangement upon detecting the AC power outage (or disengaging the fuel cell upon resumption of AC power).
