中文摘要 | 本論文旨在研究一單級化單相交流-直流轉換器。本轉換器使用單一切換開關整合交流-直流降-升壓型轉換器及直流-直流順向式轉換器。前半級操作在不連續導通模式以達到單位功率因數及低輸入電流總諧波失真。後半級亦操作在不連續導通模式,主要提供降壓操作及電氣隔離之用。本轉換器之直流鏈結電容之電壓應力較輸入電壓之峰值為低。此外,詳盡探討本轉換器之穩態分析及邊界條件。最後,設計製作一雛型電路以驗證本轉換器之性能。 |
英文摘要 | A single-stage single-phase AC-DC converter, which integrates a single-phase AC-DC buck-boost converter with a DC-DC forward converter by using single switch, is researched in this paper. The front semi-stage of the proposed converter is operated in discontinuous conduction mode (DCM) to achieve almost unity power factor and low total harmonic distortion of input current (THDi). The rear semi-stage of the proposed converter is also operated in DCM for step-down voltage conversion and electrical isolation. This converter has low voltage stress on the DC-link capacitor. The steady-state analysis and boundary condition are discussed in detail. Finally, a prototype circuit is implemented to verify the performance of the proposed converter. |
