摘要

單級電子安定器係由升壓型功率因數修正器整合半橋諧振換流器所構成，該單級電子安定器具有高效率、高功率因數以及簡單電路的優點。然而，每根螢光燈管依據不同的電極形狀、管內氣體壓力與濃度以及燈管溫度等，會有相異的操作特性。對於多燈管照明系統而言，調光控制因此將是相當重要的設計考量，透過照明亮度的調整滿足人類需求，並達成節能之目的。本論文提出一種用於驅動多根螢光燈管的DSP控制單級電子安定器，實現新的調光控制方法以調整燈管電流，並建立與測試ㄧ部雛型電路，其實驗結果驗證了所提出方法的可行性。

The well-known single-stage electronic ballast integrates a boost-type power factor corrector (PFC) and a half-bridge resonant inverter. The single-stage electronic ballast has the merits such as high efficiency, high power factor, and circuit simplicity. However, each fluorescent lamp has individual operation characteristic that depends on the electrode pattern, gas pressure and concentration, and lamp temperature. Dimming control is thus an important design consideration for a multiple lamp system. It is usually used to regulate lighting levels with human needing as well as to achieve energy saving. In this thesis, a DSP-controlled single-stage electronic ballast for driving multiple fluorescent lamps is presented. A novel dimming control scheme is proposed to regulate the lamp current. A laboratory prototype is built and tested, and it is found that unity power factor can remain under various lamp brightness control. The experimental results are therefore shown to verify the feasibility of the proposed method.
