ABSTRACT:
A power control unit of a fuel cell hybrid vehicle includes a first switching unit, a second switching unit, and a control unit. One terminal of the first switching unit is connected to a fuel cell stack and to an anode of a DC/DC converter in parallel, and the other terminal is connected to an inverter. One terminal of the second switching unit is connected to the inverter and to a cathode of the DC/DC converter in parallel, and the other terminal is connected to a cathode of the fuel cell stack. The control unit switches contact points of the first and the second switching units to selectively supply a voltage from one of the fuel cell stack and a battery to a motor.
