本論文針對冷陰極螢光燈設計一新型高壓放電檢測電路，僅使用單一主動開關，利用其高頻切換動作配合儲能元件（電容與電感）藉由諧振的方式累積電壓，再經變壓器升壓以單端輸出高壓放電。利用此電路對冷陰極螢光燈進行放電測試，可達到快速淘汰無法發光燈管之目的。此高壓放電檢測電路具有構造簡單、元件數目少與低成本等優點，並可使交流輸入電源端達到高功因。
本文根據開關導通情形建立電路的工作模式，分析電路動作原理，推導電路參數的設計流程與設計方程式，並以電腦模擬與實際電路量測作理論驗證。在燈管辨識方面，以19吋冷陰極螢光燈管為待測燈管進行檢測實例，利用光譜分析器感測燈管光輸出，轉換為光譜能
量分佈圖與色度座標分佈，以此作為辨識燈管狀態之依據，快速篩選符合冷陰極螢光燈管品管規範之產品。

In this thesis, a high voltage discharging testing circuit is proposed for cold cathode fluorescent lamps(CCFLs). The testing circuit uses only a single active power switch operating at a high frequency incorporating with reactive components to accumulate a relatively high voltage on the capacitor. This voltage is then stepped up by a transformer to provide the required high voltage for discharging the CCFLs. The circuit has the advantages of simple configuration, less component count, and low cost. In addition, a high power factor at the ac line source can be achieved.
The proposed circuit is analyzed based on the mode operation. Accordingly, the design equations are derived to determine the circuit parameters. A prototype is designed and built for testing the 19 inch CCFLs. The discharging tests are made to recognize the malfunctions during the manufacturing process. Moreover, the distributions on the spectral power and chromaticity of lamps can be examined to ensure the product quality.
