DC TRANSFER SWITCH FOR FUEL CELL SYSTEMS WITH AUXILIARY STORAGE MODULE

Abstract:

A power generation method includes providing power from a first DC power source to a load, while a second DC power source is electrically disconnected from the load, electrically connecting the second DC power source to the load and providing power from the second DC power source to the load if an output voltage from the first DC power source drops below a threshold voltage and an output voltage from the second DC power source is not below the threshold voltage, and electrically disconnecting the first DC power source from the load if an output current of the first DC power source is below a threshold current.
