Abstract
Official abstract text for this publication.
There are provided a fuel cell system capable of reducing power consumption by inhibiting an unnecessary operation of a DC-DC converter, and a power control method therefor. The fuel cell system having an inverter which is connected to a load device, a first converter which is connected between a fuel cell and the inverter and sets an output voltage of the fuel cell, and a second converter which is connected between a power storage device and the inverter and sets an input voltage of the inverter includes fuel cell required output voltage calculation means for calculating a required output voltage of the fuel cell, inverter required input voltage calculation means for calculating a required input voltage of the inverter, comparison means for comparing the required output voltage of the fuel cell and the required input voltage of the inverter, and converter operation control means for causing the operation of the first converter to be suspended when judgment is made that the required output voltage of the fuel cell is not less than the required input voltage of the inverter.
First claim
Opening claim text (preview).
We claim: 1. A fuel cell system comprising: an inverter which is connected to a load device; a first converter which is connected between a fuel cell and the inverter and sets an output voltage of the fuel cell; a second converter which is connected between a power storage device and the inverter and sets an input voltage of the inverter; and a control device which controls the first converter and the second converter, the control device comparing a required output voltage…
