螢光燈由於發光效率高、壽命較長，已廣泛地應用於各行各業以及家庭之中，成為照明燈具的主流。近年來，由於電力電子技術的大幅進步，電子式安定器已逐漸取代傳統的磁耦合式安定器，除了短小輕薄之外，更進一步提升了螢光燈的發光效率及光照品質。
在精益求精的信念下，螢光燈電子安定器的研究迭有進步，本文結合先前諸多的研究成果，進行高品質、高性能的螢光燈電子式安定器之研製。研發的新成品為單級整合式，可同時驅動多支燈管，具有功因修正、以及零熾熱電流預熱的功能。使用者更可根據亮度需求，自行決定點亮的燈管支數；且不論點亮的燈管支數為何，每支燈管都仍然保持在額定功率，並不影響安定器電源端的功因修正功能。文中除進行電路結構設計與工作特性分析之外，並透過電腦軟體進行模擬，逐步推導電路之參數設計方程式，以建立參數設計法則。最後，本文以實際製作完成的電路進行量測分析，來驗證電路的實用性與正確性。

Fluorescent lamps are nowadays the most important light sources in industrial, commercial, and domestic applications. To drive fluorescent lamps, electronic ballasts with high-frequency resonant inverter, instead of the electromagnetic ones, are increasingly used due to the benefits of lightweight, small size, high luminous efficiency, and long lamp life.
Recently, efforts are concentrated on how to reduce the product cost as well as to improve the circuit performances. To further curtail the product cost, the power-factor-correction circuit is integrated into the ballast circuit as single-stage high-power-factor electronic ballast. On the other hand, the unit cost per lamp can be substantially reduced by developing a ballast circuit which is capable of driving multiple lamps. For convenient use, the user may turn on the desired number of the lamps in accordance with the expected luminosity. A starting-aid circuit is added to eliminate the glow current during preheating. In addition, a protection circuit will be included in the multi-lamp electronic ballast. In case of operating partial lamps, a high power factor at the line input will be always retained.
In this thesis, the feasible circuit configuration is developed and design equations are derived. Accordingly, design guidelines for determining circuit parameters are provided. The laboratory circuits are built and tested to verify the computer simulations and analytical predictions.
