臺灣博碩士論文加值系統

近年來多階變流器的發展逐漸成熟，而應用於高功率、高電壓的場合中，不論是在中、高壓變頻器以及電力系統中的高壓直流傳輸與台灣最近的高速鐵路建設上，可看出其應用非常廣泛也佔有重要地位。由於功率開關元件製作技術的突破，使開關元件能承受更高的電壓、電流能力，於是使用多階變流器變成為主流。
採用多階變流器時，可大幅降低開關元件之耐壓能力，因此多階變流器可大大降低開關元件成本，增加輸出電壓階數，並降低電壓和電流諧波含量。本論文提出一種新型混合串接式多階變流器架構應用於動態電壓調整器，並以低頻切換與高頻切換混合應用方式來提高變流器性能，來補償現今許多電力干擾問題，以達到電力系統解決電力擾動之目標。
爲印證本文所提出之新型混合串接式多階變流器架構應用於動態電壓調整器可行性，將運用Matlab/Simulink 來進行分析、模擬電路架構於配電系統之電壓調整，以印證本論文所提出之系統性能及可行性。

In recent years the development of multilevel inverter has been gradually matured for high power and high voltage applications, such as high-voltage DC transmission and high-speed railroad system. Based on the manufacture technology of power semiconductors, the power switches have large voltage and current stresses and it makes the application of multilevel inverter is achieved.
Multilevel inverter can use low voltage devices to implement high or medium voltage applications. The more voltage levels are generated on the inverter such that the voltage harmonic is reduced at the inverter output side. This thesis presents a new multilevel inverter topology to implement the function of dynamic voltage restorer. Therefore the power quality at the load side can be improved by the adopted circuit topology. The system performance is verified by the computer simulation based on the MATLAB/Simulink software package.
