摘要


本文以返馳式轉換器為主電路架構結合能量回復電路,產生高壓脈衝電源以驅動管狀奈米碳管場發射光源(carbon nanotube field emission lamp, CNT lamp )。其中能量回復電路不但能消除CNT lamp 的電容效應,更能將CNT lamp 上多餘的能量送回電源端,提升系統的整體效率。本文中首先根據CNT lamp 之電氣特性建立其燈管模型;其次,詳細說明並推導各操作狀態之數學模式;再者,提供一完整的設計準則。最後以電腦模擬與實測結果驗證理論之正確性。

並列摘要


A flyback converter incorporating an energy recovery circuit is proposed to generate high voltage pulses for driving carbon nanotube field emission lamp (CNT-FEL). The employed energy recovery circuit will not only eliminate the arcing phenomenon caused by traditional DC driving, but also recover the excess energy to DC bus so as to improve the system efficiency. In this paper, we construct an equivalent model of the CNT-FEL to exhibit its electric characteristics. Moreover, the mathematical models of each operation mode are also derived. And then a complete design considerations and mathematical model are detailed. All the experimental results agree with the computer simulations to verify the theoretical predictions.
