Abstract

본 발명은 발광 다이오드(LED)의 구동 시에 역률을 보상하는 PFC(Power Factor Correction) 회로에 대해, 콘덴서와 다이오드 등으로 구성되는 PFC 회로를 2 개 이상 병렬로 복층으로 구성하고, 이 PFC 간에 노이즈 필터를 통해 개별 PFC 간의 전도성 노이즈를 차단함으로써, 저용량의 전력 수준에서도 고역률을 보장할 수 있도록 된, 복층 역률 보상 회로에 관한 것이다. 본 발명에 따른 복층 엘이디 역률 보상 회로는, 교류(AC) 전원을 공급하는 전원부; 상기 교류 전원이 인가되는 입력단 및 내부의 노이즈를 여과하는 여과부; 상기 교류 전원의 입력을 맥동 직류(DC) 전원으로 변환하는 정류부; 상기 맥동 직류(DC) 전원을 2 개 이상의 역률 보상 회로(PFC)에 의해 평활화시키고, 전도성 노이즈를 감쇄시키는 복층 보상부; 및 상기 평활화 된 맥동 직류(DC) 전원을 스위칭 동작에 따라 낮은 전압으로 변환하여 LED 어레이(Array)에 전달하여 LED 어레이를 발광시키는 LED 구동부를 포함한다. 본 발명에 의하면, 5 와트(W)의 낮은 전력 용량에서 동작하는 LED 조명등 회로의 역률이 90 % 수준을 유지할 수 있다. 또한, 7~8 와트(W)의 전력 용량에서 92 %의 역률을 유지하는 LED 조명 회로를 구현할 수 있다. 그리고, 낮은 전력 용량에서도 전도성 EMC 노이즈가 기준치를 만족하는 LED 조명 회로를 실현할 수 있다.
