摘要

本論文研究用於驅動高亮度氣體放電燈一種之單級可調光電子安定器。此一高頻電子安定器係由非對稱半橋換流器、諧振網路和高壓啟動電路所組成。由於開關具有零電壓切換特性之單級電路的採用，使得功率轉換效率能夠有效提升。展頻技術的應用解決了高亮度氣體放電燈於高頻操作下所產生音頻共振的問題。由於音頻共振問題的解決，使得無論採用責任週期調變或調頻調變技術皆可實現寬幅調光之目的。本論文對於所研究單級可調光電子安定器之穩態工作原理做詳細分析與探討，提供完整的參數設計流程。並實際研製一套用於驅動三家不同廠牌，OSRAM、GE 和PHILIPS所生產35W高亮度氣體放電燈。實驗和模擬波形用以驗證本文提出架構的可行性，結果令人滿意。

In this thesis, a single-stage dimmable electronic ballast for high intensity discharge (HID) lamps is presented. The high-frequency electronic ballast consists of an asymmetrical half-bridge inverter, a load resonant tank and a high voltage ignition circuit. High power conversion efficiency is achieved by the proposed single-stage topology with zero-voltage-switching (ZVS) feature. A frequency modulation technique is used to eliminate the acoustic resonance phenomenon of HID lamps under high frequency operation. Without acoustic resonance problem, the requirement for wide dimming range can be then accomplished by using the duty-regulated or frequency-regulated techniques. The steady-state operating principles and design procedures for the proposed single-stage dimmable electronic ballast are analyzed and discussed in detail. A 35W laboratory prototype was designed and implemented for driving the HID lamps from three major manufacturers OSRAM GE and PHILIPS. The simulation and experimental waveforms of the design example are shown to verify the feasibility of the proposed scheme. The results are satisfactory.
