新型高頻鏈逆變器的設計與實現

摘要：雙向高頻環節逆變器具有雙向功率流、高頻電氣隔離、拓撲簡潔、功率變換級數少等優點，特別適用于要求雙向功率流的逆變場合。本文深入研究了一種新型的雙向高頻環節逆變器的電路結構、拓撲與移相控制策略，對逆變器穩態原理進行了分析，并給出了關鍵電路參數的設計準則。原理試驗結果證實了理論分析的正確性。 敘詞：高頻環節 逆變器 移相控制 雙向功率流 Abstract：Bi-directional inverter with high-frequency link has the advantages such as bi-directional power flow, high frequency electrical isolation, simple topology, few stages of power conversion, and it is especially suitable for occasion in bi-directional power flow. A new-type bi-directional high-frequency link inverters circuit configuration and topology, shifting control strategy, analysis of steady principle, and design criteria for the key circuit parameters are deeply investigated in this paper . The theoretical analysis is verified by the test results. Keyword：high frequency link inverter phase shifting control bi-directional power flow
