本文旨在研製風力發電系統之功率轉換器。文中之系統由交流-直流功率轉換器及直流-交流功率轉換器組成，將變動頻率及電壓之電源轉換為固定頻率之三相電源與市電併聯。在交流-直流轉換器方面，採用三相Y接全橋半控型整流器及各相獨立全橋半控型整流器；當風速較低，風機線圈繞組之相電壓感應電動勢較低，使用三相Y接全橋半控型整流器以維持直流鏈電壓於固定範圍；當風速較強時，風機線圈繞組相電壓感應電動勢較高，使用各相獨立全橋半控型整流器以維持直流鏈電壓於固定範圍。在市電併聯方面採用直流-交流轉換器及電流控制模式以提供實功率至市電側。
本系統以高性能及低成本的數位信號處理器TMS320F2812為整體系統之控制核心，其功率轉換器之控制皆由軟體程式完成。當發電機轉速為300rpm時使用三相Y接之交流-直流全橋半控型功率轉換器及三相直流-交流全橋全控型功率轉換器系統，發電容量約為270W時整體效率為90%。當發電機轉速為400rpm時使用各相獨立交流-直流全橋半控型功率轉換器及三相直流-交流全橋全控型功率轉換器系統，提供405W的發電量至市電，其整體效率約為88%。

This thesis presents the design and implementation of power converters for wind generators. The power converter that consists of rectifier and inverter can transfer the generator power from varying-voltage and varying-frequency to 60Hz three-phase grid connected electrical power. The ac-dc converter uses three-phase wye as well as three-phase independent connections of full bridge half-controlled converter. When the wind speed is low, the ac-dc converter uses three-phase wye connection, whereas, when the wind speed is high, the ac-dc converter uses three-phase independent connection to keep dc voltage lie within the constant range. The three-phase grid connection in the proposed system uses three-phase full bridge full-controlled inverter and current control to supply real power.
A high-performance and low-cost digital signal processor TMS320F2812 is used to control the power converter. Software program is used for control. When generator runs at 300rpm, the power converter supplies 270W to utility power system with 90% efficiency using three-phase wye connection of full bridge half-controlled converter and three-phase full bridge full-controlled inverter. On the other hand, when generator runs at 400rpm, the power converter supplies 405W to utility power system with 88% efficiency using three-phase independent connection of full bridge half-controlled converter and three-phase full bridge full-controlled inverter.
