| dc.description.abstract | 本論文提出一個新型架構結合準Z源與切換電感電容之高升壓轉換器，可用於太陽能發電應用。太陽能發電系統中需要高升壓直流-直流轉換器，將低源電壓提升到預定的高電壓側。
所提出的電路架構以二次升壓轉換器為基礎，將準 Z 源架構套入取代電感，使轉換器保有輸入電流連續的特性，同時降低電容的電壓應力，並且在較小的工作週期內，達到高電壓轉換比；再藉由切換電感電容拓撲，使轉換器可模組化成多階結構，根據應用層面擴增結構，以達到目標高電壓輸出；整體電路使用單開關做切換，因此只需單個控制信號及驅動電路，降低架構複雜度。
本研究針對所提出的轉換器架構進行了詳細的計算分析，以確定各參數和規格，並提供相關計算公式，以方便實際應用。此外，透過模擬和實際電路製作，並與其他高升壓拓撲進行比較，以驗證該轉換器架構的可行性和有效性。 | zh_TW |
| dc.description.abstract | This thesis proposes a novel architecture that combines the quasi-Z-source and switched inductor-capacitor frameworks for high step-up converters, which are applicable in solar power generation systems. High step-up DC-DC converters are essential in solar power systems to elevate the low source voltage to the predetermined high voltage level.
The proposed circuit architecture is based on quadratic boost converter, where the quasi-Z-source framework is incorporated to replace the inductor. This design ensures the continuous input current characteristic while reducing the voltage stress on the capacitors. Additionally, it achieves a high voltage conversion ratio within a smaller operating duty cycle. By integrating the switched inductor-capacitor topology, the converter can be modularized into multiple stages to achieve the desired high voltage output based on application requirements. The overall circuit utilizes a single switch for switching operation, resulting in simplified architecture with a single control signal and driver circuit.
Detailed calculations and analysis are conducted in this thesis to determine the parameters and specifications of the proposed converter architecture. Relevant calculation formulas are provided for practical implementation convenience. Furthermore, simulation and experimentation are conducted to implement the circuit and compare it with other high step-up topologies. The purpose is to validate the feasibility and effectiveness of the proposed converter architecture. | en_US |
