摘要

由於具有高發光效率、較佳色溫特性、較好的演色性與較長的燈管壽命，高亮度氣體放電燈(HID Lamp)已經普遍應用於例如街燈照明、液晶顯示投影機及車用頭燈等各種商業與工業用途。傳統用以驅動氙燈之市售電子安定器，係由前級直流/直流轉換器和低頻直流/交流換流器所組成。該直流/直流轉換器通常係一返馳式轉換器，其從低電壓源(例如電池或燃料電池)汲取電能，且提供一高壓直流給後級低頻換流器。而該直流/交流換流器均操作在低頻以避免音頻共振問題，因此大而笨重。本論文研究一種用以驅動HID燈之單級高頻電子安定器，其係由相移式零電壓全橋換流器、昇壓變壓器、諧振電路及高壓啟動器所組成，所實現之電子安定器具有高功率密度、簡單電路和低成本的優點。電路動作原理與設計準則詳細地被說明。一部實驗雛型電路被實現與測試，其模擬與實驗結果驗證了所提出方法的可行性。

Abstract

Because of their much higher luminous efficacy, better color rendition, and longer lifetime, High Intensity Discharge (HID) lamps have been used in various commercial and industrial applications such as street lighting, LCD projectors, and automotive headlights. The conventional commercial electronic ballast for driving HID lamps consisted of a front-end DC/DC converter and a low-frequency DC/AC inverter. The front-end DC/DC converter is usually a Flyback converter that draws power from a low-voltage source (i.e. battery or fuel cell) and feeds a high-voltage DC bus for the post-stage DC/AC inverter. The DC/AC inverter is operated at low frequency to avoid acoustic resonance. The low-frequency electronic ballast is large and heavy. This thesis presents a single-stage high frequency electronic ballast for HID lamps. This studied ballast consists of a phase-shifted ZVT full-bridge inverter, a boost transformer, a resonant tank and a high voltage igniter. The proposed electronic ballast has the advantages of high power density, simple circuit and low cost. The circuit operating principles and design criteria are described in detail. A laboratory prototype was built and tested. The simulation and experimental waveforms verify the feasibility of the proposed scheme.
