本論文研製應用於風力發電系統之全數控電力轉換器。此轉換器前級之架構，主要利用三相昇壓型整流器將交流電壓訊號轉成直流訊號達到高功率因數、低電流諧波失真，藉此提高整體系統發電效率；而後級利用全橋式換流器將直流訊號轉成交流號達到並聯至市電系統。前後級之控制方式，分別採用相位振幅調變控制與直接電流控制。本文主要利用TMS320LF2407數位訊號處理器為控制核心，實現數位化相位振幅調變控制與直接電流控制。最後，完成1 kW全數控電力轉換器之電路雛型，並透過實驗得以驗證理論之可行性。

This thesis presents the design and implementation of full-digital controlled power converter for wind power system. In this converter, the front-end circuit is a three-phase boost rectifier which converts the AC power into DC frame with high power factor and low current harmonic distortion； The back-end circuit is a full-bridge inverter which converts the DC frame into AC frame and achieve grid-connected. The DSP control chip (TMS320LF2407) is applicable to realize digital phase/amplitude modulation control and deadbeat control in this thesis. Finally, a 1kW full-digital controlled power converter is implemented to verify the theoretical analysis.
