本論文針對T5螢光燈管,分析並設計符合其燈管特性之數位與類比混合式調光高頻換流器。為能改善調光時,當頻率變動至某頻段,將造成功率元件之電流應力增加,與增廣調光範圍,故使用混合式調光控制。實作之直流輸入電壓為400V,以驅動28W之T5螢光燈管,其具有先預熱再啟動燈管功能,並加入緩轉態區間於數位與類比混合式調光控制訊號。最後,比較類比調光、數位調光與混合式調光之效果。依據實驗結果,混合式調光之開關電流應力在輕載時較類比調光少10%,調光範圍為100%至20%,且滿載時最高效率為90%。
In this thesis, a hybrid dimming inverter for T5 fluorescent lamp is analyzed and designed. By using the digital and analog hybrid dimming, the current stress of switches at particular frequency is reduced. Also, the dimming range can be extended. A high-frequency inverter with DC 400V voltage source to drive a single T5 28W fluorescent lamp is implemented. The preheating function, starting-up function, and hybrid dimming control circuit with a soft-transition operation are implemented in the proposed inverter. Also, the effectiveness of analog dimming, digital dimming, and hybrid dimming are compared. They show that the current stress of switches is reduced by 10% at lightly load, the dimming range is 100% to 20%, and the efficiency is up to 90% at full load.
