초록
The Cold cathode fluorescent lamp(CCFL) are used to illuminate the liquid crystal display(LCD). Ballasts are required for CCFL because the lamp need high starting voltage and behave negative dynamic resistant characteristics in the desired region of operation. In this paper, the lamp impedance model is proposed, and this model is established from some equations and measured electrical characteristics of CCFL. The validity of porposed lamp model is verified from the simulation and experimental results.
