Abstract
- In this paper, a simple dimming control is presented and applied to a cold cathode fluorescent lamp (CCFL). Traditionally, the digital dimming takes back-and-fro start and cutoff of the CCFL, thereby causing current spike and hence reducing the life of the CCFL. Consequently, to overcome these problems, a dimming strategy is presented according to the frequency shift. Moreover, a full-bridge phase-shift resonant inverter is utilized to power the CCFL. Some experimental results are provided to demonstrate the effectiveness of the proposed scheme. [ABSTRACT FROM PUBLISHER]
