摘要
This study proposes an impulse power driver, which is used to eliminate arcing phenomenon and to maintain lamp luminance for field emission lamp driving. To compact the system configuration and to reduce the system cost, the flyback topology is employed as the main circuit. Next, the phase-locked loop technique is embedded to implement variable-frequency control as a feedback mechanism in this study. With the proposed control mechanism, the peak value of the impulse lamp current can be captured and regulated for stabilizing lamp luminance. Furthermore, the related design considerations are detailed. All the experimental results agree to the theoretical predictions.
