According to the present invention, a high-voltage direct current converter for an electric power vehicle comprises: an inductor unit for removing a high-frequency component included in an inputted power supply; and a converter unit configured to distribute voltage by an input-side series capacitor and an output-side series capacitor after complementary switching voltage from which a high-frequency component is removed within one cycle through a plurality of switching elements. Therefore, the high-voltage direct current converter capable of boosting while accepting a wide input is used to allow a component to be used in common, and high-frequency switching is possible to increase a power density per unit volume.
본 발명은 전기동력 자동차용 고전압 직류변환장치에 있어서, 입력된 공급 전원에 포함된 고주파 성분을 제거하는 인덕터부와, 고주파 성분이 제거된 전압을 복수의 스위칭 소자를 통해 한 주기 내에 상보적인 스위칭을 한 후, 입력측 직렬 커패시터와 출력측 직렬 커패시터에 의해 전압 분배되도록 하는 컨버터부를 포함하여 넓은 입력을 수용하면서 승압이 가능한 고전압 직류변환장치를 사용하여 부품을 공용화할 수 있는 효과가 있고, 고주파 스위칭이 가능하여 단위 부피당 전력 밀도를 높일 수 있다.
