本文針對特殊需要閃爍光源應用的場合，設計可控制螢光燈光源閃爍頻率與導通率變化的電路，並藉由直流鏈電壓調光的方式，完成控制閃爍光源的亮度。電路的架構是以D類串聯共振式換流器為主，並搭配全橋整流電路、LC濾波電路，最後再藉由高複雜度可程式邏輯元件(Cpmplex Programable Logic Device, CPLD)控制電路完成後級直流換向電路之螢光燈頻率與導通率的控制，使得輸出至螢光燈的訊號為一可調怠滯時間方波電壓與電流，而達到光源閃爍控制的目的。
實驗過程中，為確保螢光燈可正常操作於光源閃爍之模式，電路控制參數值必需調變於燈管斷弧臨界曲面之上。同時，本文也設計了一光輸出波動偵測電路，並透過光源閃爍電壓訊號的偵測，即可瞭解各調變控制參數對光輸出波動的影響。實驗最後，再將本光源閃爍產生電路應用於人體視覺不舒適性的測試，以證明本電路閃爍的效果。

A flash lighting circuit with the fluorescent lamp is designed to produce lighting flicker by means of controlling the operating frequency and the duty-ratio of the lamp voltage and current. The intensity of the flash lighting is adjusted by the DC-link voltage of the electronic ballast circuit. The circuit structure is mainly composed of the class-D series-resonant inverter, the full-bridge rectifier, the LC filter and the commutation circuit. A control circuit with complex programmable logic device (CPLD) is used to accomplish the regulation of the operating frequency and the duty-ratio, which should be carefully controlled to ensure a stable lighting arc. In the meantime, a flash lighting detected circuit is designed to transform the flash lighting into a voltage signal. Experiment tests are conducted to human visual perception to demonstrate the applicability of the flash lighting circuit.
