Abstract:
1. A power supply system of a fuel cell vehicle comprising: a load mounted on a vehicle; a fuel cell and a power storage device which are connected to the load so as to be parallel with each other; a first DC-DC converter provided between the fuel cell and the load; a second DC-DC converter provided between the power storage device and the load; a current-measuring device which measures one of an input current and an output current of the first DC-DC converter; a voltage-measuring device which measures one of an input voltage and an output voltage of the second DC-DC converter; and a controller which performs a feedback control of the first DC-DC converter such that the input current or the output current measured by the current-measuring device becomes a target current, and also performs a feedback control of the second DC-DC converter such that the input voltage or the output voltage measured by the voltage-measuring device becomes a target voltage.
