Abstract

In This Paper, at the PSPICE model is presented by Piezoelectric Transformer and CCFL and equivalent circuit of fluorescent light. Highly effective fluorescent light release for next generation is developed for 35W supremacy model three wave length T5 fluorescent lamps. Lighting a candle experiment of T5 fluorescent lamps is carried out by employing Piezoelectric Transformer power-factor improvement circuit and inverter. PLL method is used for supplying a correct frequency of Piezoelectric Transformer operating.

압전 변압기와 CCFL, 형광등의 전기적 등가회로에 의한 PSPICE 모델을 제시하였고, 차세대 35W급 초절전형 삼파장 T5 형광램프용 고효율 형광등 안정기를 개발하였다. 이 안정기는 역률개선회로와 인버터에 압전 변압기를 채용하여 T5 형광램프의 점등실험을 하였으며, 압전 변압기의 효율적인 구동과 정확한 주파수 공급을 위하여 PLL방식을 사용하였다.
