技術說明

本專利所提出的新型零電流切換並聯負載共振式轉換器，主要是以E類共振式換流器為基本電路架構，並將其加以改良設計而成。由於只需利用單一開關進行切換，與利用雙開關切換的D類共振式換流器相較之下，不但可以減少一個開關的切換損失，亦提高了整體的轉換效率。此零電流切換並聯負載共振式轉換器除了具有柔性切換的特性，同時還擁有昇壓的特性，並且在輸出端加入橋式整流器與濾波器電路，使得輸出端能有穩定的直流電壓與電流輸出，此種轉換器電路具有結構簡單、低成本及高轉換效率等優點。最後經由硬體電路實際量測之結果，證實本專利所提出的新型零電流切換並聯負載共振式轉換器可達到96%以上的高轉換效率。 This patent proposed a novel parallel-loaded resonant converter with zero-current-switching scheme, which mainly uses class-E resonant inverter as basic circuit structure and then reinforced its design accordingly. Because of its function only with a single switch, it not only can reduce the switching losses of a switch, but also increases the overall conversion efficiency. In addition to the characteristics of soft-switching, a novel parallel-loaded resonant converter with zero-current-switching scheme also owns a boosting characteristics. In general, this converter circuit has the advantages of a simple structure, the low cost and high conversion efficiency. The results is conducted through an actual measurement on hardware circuit, and experimental results that the high conversion efficiency of a novel parallel-loaded resonant converter with zero-current-switching scheme can be up to 96% in the final experiment.
