摘要

隨著氣候變遷以及石化能源有用盡的疑慮下，電動化載具因而開始成為未來發展的重點之一。在電動載具中不可或缺的即是電力轉換模組，不論是將直流轉換為交流供馬達使用的換流器，或是將電池電壓轉換至不同設備所需電壓的直流轉換器，甚至是透過交流電給予電池充電的充電器，均引入了更多的轉換模組以達到更高的性能表現及更佳的效率。在這些不同的電源轉換器中有許多相同功用的元件，因此在移動載具有限的空間中若是透過設計合適的複合電能轉換架構以及建立多模式控制律，將能有效的縮小其系統體積並且減低成本。
本論文將建立多電壓源電壓節點切換分析與切換單元矩陣控制方法，透過系統化方式統整不同轉換架構於一系統，並分析電能轉換系統之馬達電感作為共用被動元件之特性，最後實現一複合電能轉換架構已進行驗證。

With global climate change and the shortage of nonrenewable energy sources, it gives priority to the development of electric vehicle (EV). Various power conversion modules are used in EV, such as the inverter, which changes DC power into AC power. Others are DC-DC converter, which converts battery voltage to other voltage level, and on-board charger, which converts the utility voltage to a battery. More power conversion modules are therefore introduced to achieve higher performance and efficiency. Inside these modules, many devices are of the same functions. With proper hybrid electric power conversion topology and multi-modes control law, the system size and cost can be effectively reduced

In this thesis, a voltage-node-switching analysis and a switching-matrix control method are established. A systematic approach is proposed to integrate different conversion architectures into a single system. Besides, characteristics of the interoperable devices are analyzed and then the motor inductance used as passive element is thoroughly studied. Finally, a hybrid electric power conversion system is realized to verify the proposed approach.
