摘要

相較於傳統鹵素燈泡，超高壓汞燈具有較高發光效率、較佳演色性與較長的使用壽命，所以已經普遍使用於諸如液晶投影機和街燈照明等各種商業用途。本論文研究一種用於驅動液晶投影機系統中超高壓汞燈之單級相移全橋高頻電子安定器。所研究單級電子安定器具有零電壓切換特性，可達到高效率、高功率因數以及燈管電流調整等特性。所提出電子安定器之工作原理及設計考量被仔細分析與討論，一部雛型電路也被實現及測試，其模擬與實驗結果驗證了所提出電子安定器的可行性。

Because of their much higher luminous efficacy, better color rendition index, and longer lifetime than conventional halogen lamps, Ultra high pressure mercury lamps have been used in various commercial applications such as LCD projectors and street lighting. In this thesis, a single-stage phase-shifted full-bridge high-frequency electronic ballast is studied for driving Ultra high pressure mercury lamps in LCD projection systems. High efficiency, high power factor, and lamp current regulation can be achieved with the studied single-stage electronic ballast with zero-voltage switching features. Operating principles and design considerations for the proposed electronic ballast are analyzed and described in details. A laboratory prototype is designed and implemented. The simulation and experimental results for the laboratory prototype are shown to verify the feasibility of the proposed electronic ballast.
