近年來，科技的技術發展日新月異，工業負載與民生電子設備對於電力的品質需求也日益漸增，所以電網供電端的電力品質日趨重要，為了改善用電端廣泛運用電力設備造成電網電流產生大量的諧波，透過主動式前端轉換器(Active front-end converter)不僅能有效降低市電電流高次諧波亦能實現系統直流和交流的雙向能量傳輸，其可應用在為可控功率因數、直流電壓控制、交流電流控制……等等，使電網的電力品質能提高。
本論文提出使用可程式邏輯閘陣列(FPGA)為通訊架構核心，透過串列埠傳輸(Tx/Rx)的通訊方式，可以改善線阻抗所造成的回授誤差，亦能降低及命令訊號線複雜度及數位訊號處理器的回授訊號的接腳負擔。
為了實現與驗證俱備數位通訊之三相三線轉換器，本文透過建立轉換器在兩軸座標下的等校平均模型之下，使用預測電流控制、直流電壓控制、馬達驅動速度控制、發電機電壓控制，驗證三相三線轉換器的理論及開發。

In recent years, the technological development of science and technology is getting better and better, power is demanded quality with Increasing for industrial load and electronic equipment, in order to improve it that harmonic of grid current by industrial load electronic equipment, we through active front-end converter not only to reduce higher harmonic of grid current but also achieve bidirectional power flow of the system, it can apply power factor correction and DC voltage control and AC current control, etc. then power quality of the power grid can be improved.
The thesis uses field-programmable gate array as communication architecture of the system. through the method of serial communication interface, it can improve error of feedback for line impendence also reduces complexity of signal wire and the burden of the pin of the digital signal processor.
To implement and verify three-phase three-wire converter with digital communication interface, the thesis will build average model of the two-axis coordinates of the converter. the thesis will through AC current control, DC voltage control, motor drive FOC control, generator voltage control, etc. it does verify three-phase three-wire converter with digital communication interface.
