본 발명의 출력 전압 확장을 위한 충전 장치는 변압기; 출력 전압에 따라 복수 개의 스위칭 레그를 통해 직류링크 전압을 생성하여 변압기의 1차측에 전달하는 제1전원부; 변압기의 1차측의 전압과 2차측의 전압의 위상차를 제어하여 출력 전압을 제어하는 제2전원부; 제1전원부를 계통 및 변압기와 선택적으로 연결하여 제1전원부로부터 출력되는 직류링크 전압을 조정하는 릴레이부; 및 출력 전압에 따라 릴레이부를 제어하여 직류링크 전압을 조정하는 프로세서를 포함하는 것을 특징으로 한다.
According to the present invention, a switching leg switchable vehicle-mounted charger comprises: a transformer; a first power unit that generates a direct current link voltage through a plurality of switching legs according to an output voltage and transmits it to a primary side of the transformer; a second power unit that controls the output voltage by controlling a phase difference between a voltage on a primary side and a voltage on a secondary side of the transformer; a relay unit that selectively connects the first power unit to a system and the transformer to adjust a direct current link voltage outputted from the first power unit; and a processor that controls the relay unit according to the output voltage to adjust the direct current link voltage.
