摘要
在這篇論文中，我們提出一個全橋式控制用於低功率冷陰極管電源轉換器，我們利用MP1010BEF的組織結構去改善傳統用於冷陰極管電源轉換器的效能，增加輸出波形的穩定性，和解決在傳統用於冷陰極管電源轉換器電磁干擾的問題。
在我所提出的電源轉換器中，有幾個主要的重點。第一，我們改變在傳統用於冷陰極管電源轉換器架構上需增加電流饋入推挽式並聯諧振電源的方式，使每個使用者能夠有效的減少電源轉換器在EMI 發射和干擾。第二，我們提出的電源轉換器中，因為MP1010BEF的組織結構本身起動時可產生電源轉換器所需的諧振電源，故他能夠減少電子零件的使用以減少電源轉換器的體積。第三，我們提出電源轉換器中，設計能被用於沒有任何另外的外部組成部分而變微弱的類比或者觸發模式。 這電源轉換器把直流電壓轉化成點燈需求並且以一個接近純理論的正弦波來操作CCFL。 它大大增加電源轉換效率。
在這篇論文中，我們將提出以下的貢獻：
(1) 我們改變在傳統用於冷陰極管電源轉換器架構上需增加電流饋入推挽式並聯諧振電源的方式，使每個使用者能夠有效的減少電源轉換器在EMI 發射和干擾。
(2) 我們提出的電源轉換器中，因為MP1010BEF的組織結構本身起動時可產生電源轉換器所需的諧振電源，故他能夠減少電子零件的使用以減少電源轉換器的體積。
(3) 我們提出電源轉換器中，設計能被用於沒有任何另外的外部組成部分而變微弱的類比或者觸發模式。 這電源轉換器把直流電壓轉化成點燈需求並且以一個接近純理論的正弦波來操作CCFL。 它大大增加電源轉換效率。
(4) 我們以一個接近純理論的正弦波來操作CCFL，得到最佳發光效益，因為減少電子零件的使用，得到零件成本的降低。
最後，我們可以知道，我們提出的電源轉換器可以改進傳統輸出效率，並減少零件成本的浪費，並增加發光效能，得到最佳的效益。

Abstract
In this thesis, we propose a inverter of low power cold cathode fluorescent lamps(CCFL) put in use full-bridge controller. We utilize institutional framework of MP1010BEF to improve the efficiency that the tradition is in charge of the inverter for the CCFL, increase the stability of the output waveform, and solve the problem that used in the CCFL and in charge of the inverter to interfere electromagnetically in the tradition.
I bring forward about inverter, there are several main points. In the first, we need to increase the Current-fed push-pull resonant inverter and charge used in the CCFL of the inverter structure. The reduction inverter making each user effective is launched and interfered in EMI. In the second, about inverter points due to MP1010BEF’s structure can produce the resonance power that the inverter needed while starting by institutional framework, so it can reduce the use of the electronic part in order to reduce the volume of the inverter . Third, we propose inverter points, it’s exceptional design to use external component any and become faint simulation or touch off way. This is inverter to use light a lamp demand and close to direct current with one pure theory sinusoidal wave to operate CCFL to transform pigeonhole. It increases the conversion efficiency of the power greatly .
In this thesis, we will put forward the following contribution:
(1) we need to increase the Current-fed push-pull resonant inverter and charge used in the CCFL of the inverter structure. The reduction inverter making each user effective is launched and interfered in EMI.
(2)In the inverter which we put forward, because can produce the resonance power that the inverter needed while starting by institutional framework itself of MP1010BEF, so he can reduce the use of the electronic part in order to reduce the volume of the inverter .
(3)We propose power among the converter , it can have other external component any and become faint simulation or touch off way to use for to design. This inverter use to light a lamp demand and close to direct current with one pure theory sinusoidal wave to operate CCFL to come to transform pigeonhole. It increases the conversion efficiency of the power greatly .
(4)We are sinusoidal wave with one that is close to pure theory to operate CCFL , receive the best luminescence benefit, because reduce the use of the electronic part , get the reducing of the part cost.
Finally, we can know , the inverter that we put forward can improve the tradition and output efficiency , and reduce the waste of the part cost , and increase the efficiency of giving out light , receive the best benefit.
