摘要

本文中，所提出為一種簡易型式主動電力濾波器的控制方法，利用功率平衡觀念計算出補償電流大小，有別於一般傳統型利用功率觀點計算出實功率或虛功率。因使用電力電子設備而使得電源產生諧波及虛功電流，於利用主動式電力濾波器補償虛功消除諧波電流後，電源電流必須為正弦波，並與電源電壓同相位。由此觀點，強迫電源電流為正弦波並與電壓同相位，並維持主動式電力濾波器電容之電壓為定值，便能使主動式電力濾波器能消除諧波補償虛功，因不必再經複雜計算功率，方法及電路簡明了許多，成本也降低了許多。

In this paper, It is not as same as traditional method to control real power or reactive power, we use the power balance idea to compensate harmonic and reactive current by Active Power Filter(APF). Current comes from using power electronic equipment results in harmonic current and reactive power. After using APF to supply these current, the source current must be sine wave after compensating, and is in phase with source voltage. From the point of view “the APF forces the source current to be sine wave and in phase with source voltage”, then APF can compensate reactive power and eliminate harmonic current. It is not necessary to calculate average power through complicate process, the method and circuit will be more simple and less cost.
