The power supply system includes a single DC-DC converter 3 providing a DC output. To its input it has connected two independent DC power sources 4, 6, 7. One of the sources may be a fuel cell 4, and the other derived from an AC source by way of a transformer 6 and a rectifier 7 which may be a semiconductor diode, silicon controlled rectifier, or switch mode device. <IMAGE> |
