Abstract:	本論文提出了一種直流高升壓轉換器，具有零電流切換和可擴展的倍壓單元。該轉換器主要基於傳統升壓電路，融合了耦合電感和切換電容型式的倍壓單元，並且通過耦合電感的漏感和一個電容的組合，形成了諧振電路。利用諧振的原理，倍壓單元內的開關元件在截止時可以實現零電流切換，有效降低了切換損失，尤其在提升轉換器的升壓比時效果顯著。該轉換器可應用於太陽能板等可再生能源的轉換，能夠有效提升太陽能板的輸出電壓，並更有效地將能量傳輸到負載端。通過脈波調變與開關配合使用，能夠有效控制和穩定輸出的電壓，提高系統的效率和穩定性。本論文詳細分析了轉換器的運作原理，以及在穩態下各個元件的電壓與電流應力。此外，對每個元件的參數進行了仔細設計。最終，透過模擬軟體和實體轉換器實驗，進行了詳盡的比較分析，以驗證了轉換器理論分析的正確性。;This paper proposes a DC-DC boost converter with zero-current switching and an expandable voltage multiplier cell. The converter is primarily based on traditional boost circuits but combines couple inductor and expandable voltage multiplier cell in the form of the switch capacitors. By combining the leakage inductance of coupled inductors with a capacitor, a resonant circuit is formed. Utilizing the resonance principle, the switching elements within the boosting unit achieve zero-current switching during the off state, effectively reducing switching losses, especially when increasing the converter′s boosting ratio This converter can be applied to renewable energy sources such as solar panels, effectively increasing the output voltage of solar panels and transferring energy more efficiently to the load side. By using pulse-width modulation and switches, the output voltage can be effectively controlled and stabilized, improving system efficiency and stability. The paper provides a detailed analysis of the converter′s operation principles and the voltage and current stresses on each component under steady-state conditions. Furthermore, the paper carefully designs of parameters for each component. Ultimately, through simulation software and experimental validation with physical converters, comprehensive comparative analysis is performed to verify the correctness of the converter′s theoretical analysis.
