Zusammenfassung:	PURPOSE: A smoothing circuit is provided to prevent a degradation of performance of electrolytic condenser by removing high frequency ripple components through the use of an additional circuit which does not change characteristics of smoothing circuit. CONSTITUTION: A smoothing circuit comprises low frequency ripple component removing electrolytic condensers(C8,C9) having ends connected to an input side; inductors(L1,L2) having ends connected to the other ends of the electrolytic condensers; anti-reverse diodes(D6,D7); and high frequency ripple component removing condensers(C80,C90) having ends connected to an input side. The high frequency ripple component removing condensers are film condensers. 본 발명은 리플성분 제거용 평활회로에 관한 것으로서, 일단이 입력측에 연결되어 있는 적어도 하나 이상의 저주파 리플성분 제거용 전해 콘덴서(C8, C9); 일단이 상기 전해 콘덴서(C8, C9)의 타단에 연결되어 있는 인덕터(L1, L2); 역전방지용 다이오드(D6, D7); 및 일단은 입력측에 연결되어 있는 적어도 하나 이상의 고주파 리플성분을 제거하기 위한 콘덴서(C80, C90); 를 포함한다. 바람직하게는 상기 고주파 리플성분 제거용 콘덴서(C80, C90)는 필름 콘덴서인 것을 특징으로 한다.
