Abstract :
A micro-fuel cell power supply system realizes an electronic ubiquitous society. Especially, the micro-fuel cell power supply is promoted to apply mobile systems such as small personal computer, cellular phone and so forth. In this case, it is attracted strongly to employ both of the micro-fuel cell and battery as the hybrid power supply system. This paper proposes a hybrid type DC-DC converter with new control strategy for the micro-fuel cell power supply system, and provides the operation principle, the experimental result and so forth. The new hybrid type DC-DC converter has a new output power compensation and new optimum operating point tracker using the microcomputer. As a result, the new hybrid type DC-DC converter can operate stably against the variation of power from the micro-fuel cell and the variation of the load current
