Abstract

In this paper, the modelings of PSPICE of the piezoelectric transformer and CCFL drive circuit using an electrical equivalent circuit is proposed. In the CCFL drive circuit modeling the model parameters of the CCFL were derived using the method of least squares because push-pull inverter and loads such as CCFL were also modeled using PSPICE. It is considered that the simulation techniques can be used in the piezoelectric devices such as piezoelectric transformer.

본 논문에서는 압전 변압기와 CCFL 구동회로의 전기적 등가회로에 의한 PSPICE와 모델을 제시하였다. 램프모델은 최소 제곱근을 이용하여 모델의 파라미터들을 유도하였다 이 모델에 대한 확증을 위해 CCFL 구동회로의 단독모델을 가지고 시뮬레이션을 수행한 결과 정확한 모델링이 되었음을 확인하였으며, 압전변압기는 푸시풀 인버터와 부하로써 주로 PSPICE로 모델링한 CCFL을 사용하여 시뮬레이션을 수행한 결과 만족스러운 모델링이 이루어졌음을 알 수 있었다.
