POWER CONVERTER ARCHITECTURE AND METHOD FOR INTEGRATED FUEL CELL BASED POWER SUPPLIES
摘要
A fuel cell based power supply comprises a main power converter architecture that allows the fuel cell stack to operate independently of a desired output voltage. The fuel cell stack may be directly connected to the main power converter eliminating high current switches and diodes. Switches are operable to selectively power an auxiliary component such as a cooling fan to the fuel cell stack or to a storage device via an auxiliary power converter. A single auxiliary power converter can replace a dedicated cooling fan power supply. The power supply operates in a variety of states.
