本論文旨在研製一高升壓比直流-直流轉換器,可應用於需要高升壓比的場合。本電路採用正向串接的架構,優點在於電路架構簡單、元件數目少、控制方便等,且於責任週期操作於0.7的範圍內即可得到8倍以上的升壓比。本文首先將介紹此高升壓比直流-直流轉換器的操作模式,並分析其動作原理。最後,研製出一輸入電壓50 V、輸出電壓400 V、功率2000 W、效率90 % 的高升壓比直流-直流轉換器,並由實驗結果驗證理論分析之可行性。
In this thesis, a high step-up ratio boost converter is investigated and implemented. This circuit can be used in the situation requiring high step-up conversion ratio. It uses positive cascade structure to achieve the high step-up conversion ratio requirement. The advantages of the circuit include simple structure, small component count, and easiness to control …etc. Moreover, when duty cycle operates below 70%, the step-up conversion ratio can be more than 800%. This thesis will firstly introduce the operation mode of the high step-up ratio boost converter and analyze its operation theory. Finally, a 50 V input voltage, 400 V output voltage, 2000 W output power and a efficiency higher-than 90% efficiency high step-up ratio boost converter is designed and implemented to verify the feasibility of this high step-up ratio boost converter circuit.
