| 摘 要： | 采用超高频电子镇流器能有效克服高强度气体放电灯所固有的声谐振问题。本文提出了一种新型可调光的超高频电子镇流器。基于T型滤波器的调光方法,能在很窄的工作频率范围内实现深度调光,同时具有灯电流波峰因数低的优点。理论分析与实验结果验证了该电路的有效性。

| Abstract: | Electronic ballast with ultrahigh frequency (UHF) can avoid the intrinsic problem of acoustic resonance of HID lamps.A novel UHF electronic ballast with dimming feature is proposed in this paper.Based on T type filter,the new ballast can achieve a wide dimming range with a very narrow frequency variation range,and it can operate with low lamp current crest factor. Its validity is proved by theoretical results and experimental results. |
