Abstract

To drive the CCFL In LCD backlight inverter, a new transformer structure with small volume is proposed which have a boosting voltage and a lamp current balancing functions. The proposed transformer structure has been verified through experimental test with 40inch LCD backlight inverter.

LCD backlight 인버터의 Cold Cathode Fluorescent Lamp(CCFL)를 구동하기 위해 승압 기능과 전류 평형 효과를 동시에 갖는 트랜스포머에서 부피 및 원가 저감 효과를 갖는 새로운 구조의 트랜스포머를 제안하였다. 제안된 트랜스포머의 타당성을 검증하기 위해 실제 40인치 LCD backlight 인버터에 적용하여 실험을 수행하였다.
