Abstract

LED light driving device has problems in efficiency and heating at higher than 150W. In addition, there is inconvenience in replacing the lighting device to another when W is not the same as the previous one. In this paper, a multi-channel LED light driver, driver embedded driver circuit in a multi-channel structure with a power system in the driver-interlocking structure was designed. With the auto control converter structure with a power efficiency above 93% and power factor above 0.98, the weight of the high efficiency LED lighting-actuating device in driver-interlocking structure, a driver in self-calibrating self-optimization structure. In this paper, at below 10% THD, the existing converter contrast weight was reduced by 40% or more.

LED 조명 구동장치는 150W 이상에서 효율과 발열문제가 있고 W(와트)수가 다른 조명기기를 교체하는데 불편함이 있다. 본 논문에서는 멀티채널 LED 조명 구동장치를 드라이버 연동형 구조의 전원시스템과 멀티채널 구조형태의 드라이버 회로내장형으로 설계하였다. 본 개발품은 전원효율 93% 이상 및 역율 0.98 이상의 자동 제어 컨버터 구조로써 드라이버 연동형 구조의 고효율 LED 조명 구동장치와 자기보상방식의 자기최적화 구조의 드라이버다. 따라서, 본 논문은 THD 10% 이하와 기존 컨버터 대비 중량이 40% 이상 감소하였다.
