在未來的幾十年，T5 螢光燈管將成為照明事業可期待的一個趨勢。因此，本論文主要是研製兩種使用於驅動T5燈管的電子安定器: 離散式控制器與組合式控制器之功率因數修正串聯半橋變頻器。除此之外，本文將介紹安定器對燈管之可規劃驅動以及一些保護功能。為了提高燈管驅動順序以及穩態操作的效能，本論文將提出一種改良式的電壓預熱方法。
本論文電路使用離散式與組合式控制器，配合串聯諧振並聯負載架構以驅動28W T5單燈管，提供各個控制器合適的參數與元件設計流程，以實現高性能電子安定器。最後在相同燈管及元件的操作條件下量測實驗結果，比較離散式以及組合式控制器的電子安定器特性。

T5 linear fluorescent lamp (FL) is expected to be a trend in lighting industries for the oncoming decades. In line with the trend, this thesis focuses on the study and implementation of high-frequency electronic ballasts for T5 FL using discrete controller and integrated controller for the PFC-inverter combination. Programmable lamp start-up and ballast protection features are introduced. An improved voltage-mode cathode preheating is also proposed to enhance the lamp ignition process and upgrade lamp performance during a steady-state operation.
The experimental prototype adopting a series-resonant parallel-loaded topology for driving a single 28W T5 lamp is implemented with both discrete ICs and several combo IC controllers. Design issues of the circuit parameters and component calculations for each controller are studied and practically executed. Experimental results under same specifications are provided and comparisons among the various ballasts are discussed.
