本論文發展一套自激式感應發電機之升壓式功因修正整流轉換器及可控換流器控制策略，以改善自激式感應發電機之輸出電壓及頻率會隨不同轉速及不同負載條件而發生變動的特性。
本論文所提出功率轉換器為兩級架構，利用IC UC 3854與數位信號控制器dsPIC30F4011來控制各級的功率級電晶體，三個單相升壓式功因修正電路將風力用感應發電機之交流電源轉換成穩定直流電壓，並改善發電端輸出功率因數；單相換流器則用來產生穩定交流電源輸出。
本論文利用電力電子暨馬達模擬軟體PSIM完成整體系統之模擬，並以實際電路進行測試比較，以驗證本論文所提系統之可行性，由研究結果顯示當自激式感應發電機轉速運在1300 rpm ~ 1600 rpm時，均可維持穩定的輸出電壓。

The aim of this thesis is to develop a control strategy for power-factor-correction converters and a controllable DC-to-AC inverter for a self-excited induction generator whose both output voltage and frequency are inherently affected by random wind speed and connected loads.
The proposed power converters are properly controlled using an IC UC 3854 and a digital signal controller dsPIC30F4011. Three single-phase power-factor-correction converters are connected to the self-excited induction generator to control the DC-link voltage and correct the output power factor of the self-excited induction generator. Single-phase inverter is employed to produce fixed AC voltage and frequency for the connected single-phase AC loads.
The studied system is simulated by PSIM and the simulated results are validated by experimental tests. The results show that the stable output voltage can be maintained when the speed of the studied self-excited induction generator is varied from 1300 rpm to 1600 rpm.
