Title:
SYSTEM FOR PROVIDING BACKUP POWER FROM A REGENERATIVE FUEL CELL OR BATTERY ARRANGEMENT
Document Type and Number:
WIPO Patent Application WO2004025799
Kind Code:
A3
Abstract:
A regulated DC power supply facilitates extended and uninterrupted power to a load (14) by using a secondary power source such as a regenerative fuel cell (24) that has its DC power output (30) conditioned by a power converter (26, 28). The DC power supply includes a rectifier (20, 22) that converts AC power (16) from an AC power source to DC power for a load (14) coupled to a DC bus (17). A fuel cell (24) arrangement is electrically coupled to a power converter (26, 28) that is coupled in turn to the DC bus (17), the converter conditions an unconditioned DC power output of the fuel cell (24) to the load (14). A system controller (18) is communicatively coupled to the rectifier (20, 22), the converter (26, 28) and to a fuel cell controller (25) , the fuel cell controller (25) initiating DC power output from the fuel cell arrangement (24) upon detecting the AC power outage or disengaging the fuel cell upon resumption of AC power.
