摘要

本論文主要目的為以數位訊號處理器(digital signal processor, DSP)實現高性能功率因數修正器之研究。利用此電路可解決傳統交直流整流器功率因數低落、諧波失真大及電路元件龐大、控制迴路補償不易調整等問題。本論文控制器的架構採用多迴路方式之交錯式控制，其中包括電流內迴路與電壓外迴路，本論文首先利用Matlab / Simulink建立系統模型，以驗證所設計之控制器的性能與可行性。
本論文以eZdsp TMS320F2808控制卡實現所設計之控制器，並利用 eZdsp TMS320F2808所提供之HRPWM、IQMATH功能應用於功因修正器中，以達到數位化系統體積小、設計彈性大等目的。經由實測結果，本論文所設計之功因修正器在不同之狀態下均可將功因提昇至95%以上。

The main purpose of this thesis is to using the digital signal processor (DSP) to realize a high performance power factor corrector. By using the proposed circuit, the problems of low power factor, high harmonic distortion, large scale circuit components and difficult to adjust the controller in the conventional rectifier circuit can be solved.
In this thesis, the controller structure is constructed by a multi-loop scheme, which includes the inner current loop and the outer voltage loop. First, this thesis uses the MATLAB / SIMULINK simulator to build a model for the verifications of the performance and feasibility.
The realization of the digital controller is made by a eZdsp TMS320F2808 DSP starter kit (DSK). Finally, this thesis provided by use eZdsp TMS320F2808 of HRPWM, IQMATH functional used in power factor corrector.
