摘要
本文提出一套具高輸入電壓變動性之適應能力複合型電漿驅動電路。由於一般電漿驅動系統大部分著重於單一場合應用設計，導致缺乏其應用之彈性，另外，當應用場域所提供之電壓變動性較高時，將導致電漿驅動失效的可能性。因此，本文提出一套複合型電漿驅動電路，整合升降壓電路及橋型電路，使其電漿驅動電路可適應較高的輸入電壓變動。此外，應用電漿負載特性搭配諧振電路設計，不但可有效提高其電壓增益，有利於驅動電漿負載，還可達到柔切條件以有效提升傳輸效率。為了證明本文所提之複合型電漿驅動電路之可行性，已於實驗室中建構一雛型電路並進行測試。經由實驗結果佐證本文所提之電漿驅動電路具有高輸入電壓變動性之適應能力，其研究成果確實提升電漿驅動系統的應用便利性，且頗具設計參考價值。
關鍵詞：高輸入電壓變動性之適應能力、複合型電漿驅動電路、升降壓電路、橋型電路
Abstract
This paper proposes a compound plasma-driven circuit with adaptability to high input-voltage variations. Most of the general plasma drive systems are designed for single-field applications, which lacks the flexibility of applications, and when the voltage variation of the application field is high, the plasma drive may fail. Therefore, this paper proposes a compound plasma-driven circuit, which integrates a buck-boost circuit and a bridge-type circuit, so that the proposed circuit can accommodate higher input voltage variations. Furthermore, by applying the plasma load characteristics with the resonant circuit design, not only can the voltage gain be effectively enhanced to be beneficial for driving the plasma load, but also the conditions of soft-switching can be achieved to effectively improve the transmission efficiency. To demonstrate the feasibility of this proposed plasma-driven circuit, a prototype circuit was built and verified in the laboratory. The experimental outcomes confirm that the proposed plasma-driven circuit is capable of high input voltage variation. The results of the research have surely improved the convenience of the application for the plasma-driven circuit and are of a reference value for design.
