Zusammenfassung:	The present invention relates to a DC/DC converter control device for controlling a DC/DC converter connected to an output terminal of a grid-connected inverter which comprises: a voltage controller generating a command value for constantly controlling an output voltage of a DC/DC converter; a pulsation removal unit generating a compensation value for removing a pulsation component included in an output terminal voltage of the grid-connected inverter; and an adder for summing the command value received from the voltage controller and the compensation value received from the pulsation removal unit. 본 발명은 계통 연계형 인버터의 출력 단에 연결되는 DC/DC 컨버터를 제어하기 위한 DC/DC 컨버터 제어장치에 관한 것으로, 상기 DC/DC 컨버터의 출력 전압을 일정하게 제어하기 위한 지령치를 생성하는 전압 제어기; 상기 계통 연계형 인버터의 출력 단 전압에 포함된 맥동 성분을 제거하기 위한 보상치를 생성하는 맥동 제거부; 및 상기 전압 제어기로부터 수신된 지령치와 상기 맥동 제거부로부터 수신된 보상치를 합산하는 가산기를 포함한다.
