　　傳統上由二極體或閘流體所組成的整流器架構之電流諧波成份，已不符合IEC61000-3-2 Class A 諧波限制的規範。本論文旨在研製一以數位訊號處理器為基礎之三相昇壓型整流器，而三相昇壓型整流器，可以達到輸入電流為弦波、降低輸入電流諧波成份並使線電流與輸入電壓波形同相位，達成功率因數修正之目的。本文探討三相昇壓型整流器其動作原理與常見的控制方法，並對該整流器推導其狀態平均方程式，進而推導出三相昇壓型整流器輸出電壓及昇壓電感之限制值。此外，由於本轉換器為雙向性的架構，因此另說明雙向功率潮流控制原理。最後，本論文完成一1 kW三相昇壓型整流器系統，此系統運用TMS320LF2407數位訊號處理器實現正弦脈波寬度調變控制，並以PSIM電路模擬軟體模擬及實作結果來驗證本論文之理論及設計的正確性。

　The current harmonics of the traditional diode/SCR rectifiers can not meet the IEC61000-3-2 Class A regulation. In this thesis, a DSP-based three-phase boost
rectifier is studied and implemented. The three-phase boost rectifier control the line current with sinusoidal waveform and in phase with line voltage. Thus, low harmonic current and high power factor can be achieved. The detailed operational principle and the control method of the three-phase boost rectifier are described in this thesis. In addition, the solution of the state-space average equations is discussed. Therefore, the constraints of the output voltage and the boost inductance are determined. The three-phase boost used as bi-directional power flow is briefly discussed. Finally, the TMS320LF2407 DSP control chip is employed to realize 1kW three-phase boost rectifier. The PSIM simulated results and practical measured results are perform to validate the theoretical analysis.
