摘要
隨著科技產業的日益進步以及電力電子技術的發展，各式以二極體組成的整流電路被廣泛的使用在日常生活當中，而當中所產生的電流諧波，造成電力品質的低落效率的降低並嚴重的汙染了電源系統；對於連接於電力系統中的精密設備而言，不但造成了大量的虛功損失，甚至也嚴重的干擾到通訊系統及電腦儀器系統的正常操作。隨著電子設備應用的大幅成長，為了解決這個問題，許多研究紛紛的被提出，其中最普遍採用的系統就是主動濾波器。 目前主動濾波器依照架構不同可分為並聯式、串聯式和混合式三種。而在本文中，依照不同的架構特性針對不同的負載作諧波補償、功因修正和提高電力品質，此外會對操作原理與架構予以分析與介紹此三種架構的控制方法以及以DSP為控制中心，使系統可更快達成所設定的目標，最後由實驗結果證明所使用方法之可行性。

Due to widely used of the power electronic equipments and the progress of power electronics technologies, applications of power converter have increased significantly in recent years. The power quality is getting worse by the increasing of harmonics in current. Many researches for solving this problem have been presented in recent years, the most popular are adopting active power filters. At present, active power filters can be divided into three categories, there are shunt APF, series APF and hybrid APF. In this thesis, different structures of active power filters were proposed for a system with different harmonic source loads to achieve low harmonic pollution and high power factor. The operation principle and control structure of the active power filter was analyzed and introduced. Then, a digital signal processor (TMS320F240) was used as the control center, and finally, the feasibility of the proposed control was verified from experimental results.
