隨著現今科技產業對於精密儀器之用電品質日趨重視，裝設電力調節設備已漸為用戶視作改善電力品質之重要解決方案，其中動態電壓恢復器由於具有架構簡易、設置彈性、成本低廉及補償效果良好等特性，因此廣為電力用戶所採用。惟目前動態電壓恢復器雖已解決市電欠電壓問題，但於穩定性之提升上，仍具可研究改進之空間，因此本論文應用K因子設計理論，透過極-零點補償方式對於系統之增益邊限與相位邊限，進行適當調整，以設定適宜之控制器參數值，進行系統輸出波形之修正與補償，期能提升系統之響應速度與穩定性，並提供相似電力調節設備控制器之研製測試參考。
而為佐證本研究之可行性，本文首先藉由整體系統架構之波德圖進行分析與探討，續利用電腦輔助實體電路進行波形之預測與評估，並經由硬體電路測試予以驗證，可知本文所提之系統架構確具有提供電壓補償與穩定負載端電壓之能力，應有助於電力品質研究之參考。

With the increasing importance of the quality of supplying power for the precision equipment, the implementation of voltage-regulated devices has emerged to be highly concerned. Particularly, because the merits of compact structure, high flexibility, low cost and satisfactory compensation performance, the usage of dynamic voltage restorers to cope with voltage sag problems is popularly accepted by industry customers, yet the improvement of stability is still a topic to strive for. Therefore, in this thesis, the K-factor theory is employed with the embodiment of pole-zero compensation to reach a better gain margin and phase margin, thus anticipating the response and stability are both achieved such that the method can be also served as a useful design and testing reference for voltage-regulated equipment.
Meanwhile, in order to validate the feasibility of the method, the thesis has investigated the Bode plot of the system structure, by which the software evaluation and hardware validation of the designated circuit were prudently performed. From those simulation results and experimental outcome, they have demonstrated the capability of the method in voltage compensation and stability improvement, thereby supporting the method for the electric power quality studies.
