컨버터를 통해 메인버스단에 연결된 연료전지; 컨버터 출력측에서 메인버스단에 병렬연결된 보조전원; 및 컨버터의 목표입력전압을 가변하여 연료전지의 출력을 조정하도록 컨버터를 제어하며, 컨버터의 출력전압이 설정된 최대값 이상인 경우 컨버터의 목표입력전압을 증대시키고, 컨버터의 출력전압이 설정된 최소값 이하인 경우 컨버터의 목표입력전압을 감소시키는 제어기;를 포함하는 연료전지 시스템 및 그 제어방법이 소개된다.

    A fuel cell system includes a fuel cell connected to a main bus through a converter, an auxiliary power supply connected in parallel to the main bus at an output side of the converter, and a controller electrically connected to the converter and configured to control the converter to adjust output of the fuel cell by changing a target input voltage of the converter, configured to increase the target input voltage of the converter when an output voltage of the converter is a set maximum value or more than the set maximum value, and configured to decrease the target input voltage of the converter when the output voltage of the converter is a set minimum value or less the set minimum value. Furthermore, a method of controlling the fuel cell system is disclosed.
