摘要

本論文研究一種用於多燈管驅動之高頻電子安定器，其係由單級非對稱半橋換流器、負載諧振電路和切換電容調光控制電路所組成。所提出具有零電壓切換特性之單級電路架構可確實達到高效率和單位功率因數要求。一種切換電容調光控制技術也被詳加研究，以提供寬廣的調光範圍、獨立與平衡調光及較佳的電磁干擾特性。所提出單級可調光電子安定器之工作原理和設計程序詳細地被分析及討論。一部雛型電路也被實現和測試，其模擬與實驗結果可驗證所提出方法之可行性。

In this thesis, a high frequency electronic ballast that consists of a single-stage asymmetrical half-bridge inverter, a load resonant tank and a switched-capacitor dimming control circuit is proposed for driving multiple fluorescent lamps. High efficiency and unity power factor are achieved by the proposed single-stage topology with zero-voltage-switching property. A switched-capacitor dimming control technique is also studied to provide wide dimming range, luminance balance, independent dimming and better EMI features. The steady-state operating principle and design procedure for the proposed single-stage dimmable electronic ballast are analyzed and discussed in detail. A ballast prototype was implemented at the laboratory. The simulation and experimental results verify the feasibility of the proposed method.
