Abstract
(EN)
The present invention relates to an impedance matching filter using an RCR series circuit and an insulated LED dimming converter using same, the filter allowing an RCR series circuit to be connected in parallel between a secondary output terminal of a transformer and an input terminal of an alternating current rectifier so as to correct, through symmetrical resistors and a capacitor structure interposed therebetween, a difference in impedance between a secondary side of the transformer and the alternating current rectifier, thereby changing the noise phase thereof to an in-phase so as to significantly reduce a phase difference.

La présente invention concerne un filtre d'adaptation d'impédance utilisant un circuit en série RCR et un convertisseur de gradation de DEL isolé l'utilisant, le filtre permettant à un circuit en série RCR d'être connecté en parallèle entre une borne de sortie secondaire d'un transformateur et une borne d'entrée d'un redresseur de courant alternatif de façon à corriger, par l'intermédiaire de résistances symétriques et d'une structure de condensateur interposée entre celles-ci, une différence d'impédance entre un côté secondaire du transformateur et le redresseur de courant alternatif, ce qui permet de changer la phase de bruit de celui-ci en une phase en phase de façon à réduire de façon significative une différence de phase.

본 발명은 트랜스포머의 2차측 출력단과 교류 정류부의 입력단 사이에서 RCR 직렬 회로를 병렬 연결함으로써, 좌우대칭 형태의 저항과 그 사이에 개재된 커패시터 구조를 통해 트랜스포머의 2차측과 교류 정류부 사이의 임피던스 차를 보정하여 노이즈의 위상을 동위상으로 변경하여 위상차를 현저히 감소시킬 수 있는 RCR 직렬 회로를 이용한 임피던스 매칭 필터 및 이를 이용한 절연타입 LED 디밍 컨버터에 관한 것이다.
