摘要

本論文主要目的在研究新型暫態偵測器以實現高性能功率因數修正器。利用此電路可以解決傳統的功率因數修正器因為降低電壓迴路控制頻寬所造成暫態響應不佳的問題。控制器的架構採用多迴路之交錯式控制方式，其中包括電流內迴路與電壓外迴路，此外，暫態偵測器將裝置在電壓外迴路架構中，以改善電路的暫態響應。
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，並以eZdsp TMS320F2808控制卡為平台配合VisSim/ECD實現所設計之控制器。經由實測結果，本文所設計之功因修正器可將功率因數提昇至99%，並且驗證在負載變動時，能維持電路良好的暫態響應。

The main purpose of this thesis is to develop a new transient detector to realize a high performance power factor corrector. By using the proposed circuit, poor transient response problems in the PFC circuits could be improved by switching two special design. The controller is constructed by a multi-loop scheme, including a inner current loop and an outer voltage loop. The purposed transient detector is installed in the voltage outer loop to improve the transient response.
We use the MATLAB/SIMULINK simulator to build a model, and to verify the performance and the feasibility of this scheme. The realization of the digital controller is made by a eZdsp TMS320F2808 DSP starter kit (DSK) and coded by the VisSim/ECD. Finally, the power factor can be improved up to 99% and a good transient response can still be maintained on the purpose circuit.
