高性能AC/DC/AC轉換器之分析與設計
Analysis and Design of a High Performance AC/DC/AC Converter
摘要
本文旨在研究以前饋控制法則來改善傳統直流連接型AC/DC/AC轉換器，以達到大幅降低直流連接處所需之電容量，約僅需傳統技術之3%，故能以壽命較長之油質、薄膜或陶質（oil、film or ceramic）電容器來取代之。並可達縮小體積及延長壽命之目標。而且，在其交流輸入側之電流仍為純弦波且功率因數趨近壹。另一方面，並提出系統化之方法以設計功率電路，以確保轉換器之正常還轉。除此之外，以解析之方法設計前饋控制器之各項參數，最後，以電腦模擬來驗証其可行性。

This paper describes how to reduce an electrolytic capacitor from the DC-link ACIDC/AC converter which makes several troubles. It shortens life time within several years and increases the converter size. Moreover, it decreases the power factor and increases the harmonics on input lines because of the pulsewise input current.These problems would be cleared up if the capacitor is eliminated. This paper describes feedforward control method to eliminate the large electrolytic capacitor without changing the power circuit. A critical condition is derived for successful current tracking. A systematic design method for the feedforward controller is presented to find the parameters of the controllers. Some simulation results are presented for verification.
