本文提出一新型N倍壓整流電路，以因應再生能源發電系統轉換器所需之高升壓比。此新型N倍壓整流電路之控制策略係基於分時多工原理，使輸出整流二極體與輸出電容在不同時間點進行能量傳遞及儲能。該電路架構與傳統倍壓整流電路架構相較下，該架構可降低輸出電容與輸出整流二極體的電壓應力，使各個輸出電容電壓幾乎可達到均壓，最後由輸出電容電壓疊加，讓輸出電壓達到N倍壓之成效。本文實際研製一新型全橋四倍壓轉換器，其規格為48V直流輸入、200V直流輸出、及額定功率150W，並模擬與傳統全橋四倍壓轉換器在電路各元件應力上的差異。由實驗與模擬結果可以看出，本文所提出之新型全橋四倍壓轉換器，其電路的輸出電容電壓應力確實小於傳統全橋四倍壓轉換器。本文亦模擬利用所提出之N倍壓整流電路於高升壓比的結果，由模擬結果可以看出，本文所提之新型N倍壓整流電路應可用於再生能源發電系統轉換器所需之高升壓比電路。

This thesis proposes a novel N-times voltage multiplier rectifier for high step-up converters which can be used in renewable energy generation systems. This control strategy for the proposed N-times voltage multiplier rectifier circuit is designed based on Time Division Multiplex (TDM) principle. The TDM control strategy can be used to transfer and save energy for the output rectifier diodes and output capacitors at different time intervals. The circuit configuration and TDM control strategy can reduce voltage stress for the output capacitors and output rectifier diodes. Each voltage of output capacitor can almost achieve the purpose of equalizing voltage. The functionality of N-times output voltage can then be realized because of the superposition of the output capacitor voltages. A full-bridge quadrupler converter integrating the proposed rectifier with the specifications of the 48V DC input, 200V DC output, and rated power 150W is designed and implemented in this thesis. Experiments and simulations for the proposed full-bridge quadrupler converter and the conventional full-bridge quadrupler converter are conducted to compare the voltage stress of each circuit component. The results show that the voltage stress of output capacitors in the proposed full-bridge quadrupler converter is less than the voltage stress of output capacitors in the conventional converter. In addition, this thesis also simulates the applications of the proposed N-times voltage multiplier rectifier for high step-up conditions. Simulation results indicate that the proposed N-times voltage multiplier rectifier has great potential to be used in high step-up converters of renewable energy generation systems.
