The present embodiment includes an input terminal and an output terminal connected to the input terminal and improving power factor through the input terminal. The output terminal has a non-electrolytic capacitor formed at both sides of an electrolytic capacitor for output. A first inductor is formed between the non-electrolytic capacitor and the electrolytic capacitor. In this embodiment, the ripple current (current stress) of a PFC output terminal is reduced through a CL circuit formed on the left side of the electrolytic capacitor. An input ripple current (input current stress) of a DC-DC converter can be reduced through a LC circuit formed on the right side.

    본 실시예는 입력단과, 상기 입력단에 연결되어 입력단을 통해 역률을 개선하는 출력단을 포함하고, 상기 출력단은 출력용 전해 커패시터를 중심으로 양측에 비전해 커패시터를 형성하고, 상기 비전해 커패시터와 상기 전해 커패시터사이마다 제1 인덕터를 형성한다. 이에, 본 실시예는 전해 커패시터를 중심으로 좌측에 형성된 CL 회로를 통해 PFC 출력단의 리플 전류(전류 스트레스)를 저감시키고, 우측에 형성된 LC 회로를 통해 DC-DC 컨버터의 입력 리플 전류(입력 전류 스트레스)를 저감시킬 수 있다.
