本論文提出一種驅動多組冷陰極燈管之諧振換流器架構，文中採用D型並聯諧振換流器為主電路架構，再藉由單組變壓器即可並聯驅動多組冷陰極燈管，其次，諧振換流器直接利用功率因數修正器之高壓直流輸出為其供應電源，減少了傳統背光模組因採用低壓輸入電源而需另加入降壓轉換器的需求，藉此可大幅降低液晶顯示器構件之成本與配置之體積。本論文除了詳細說明電路架構中各元件值之設計考量，並提出一設計實例，最後以模擬與量測結果驗證所提控制策略之正確性。

A multi-lamp driver for cold cathode fluorescent lamp (CCFL) with a resonant inverter is proposed in this thesis. Conventionally, a backlight module requires a buck converter to provide a low DC input voltage for driving the inverter. The circuit cost is high and the power transfer efficiency is affected. In this thesis, the 400V DC output voltage of a power factor corrector (PFC) directly powers a Class-D parallel resonant inverter. Also only one transformer is used to drive the multiple lamps. The cost and volume of the backlight module assembly are reduced. Complete analysis and design considerations are discussed in detail in this thesis. Experimental and simulation results are close to the theoretical prediction.
