摘要
近些年来,有源电力滤波器作为抑制谐波和补偿无功的有效工具,引起了人们很大的重视。三电平技术的引入极大地促进了有源电力滤波器的发展,与传统的两电平相比具有很大的应用优势。由于自身结构的特点,导致调制算法和直流侧中点电压平衡控制的复杂性。为此,众多的学者对此进行了深入的探索和研究。本文对二极管中点箝位式有源电力滤波器的研究和发展进行了概述。
Active power filter （APF） has caused more attention in the past few years since it is a tool that can suppress the harmonic current and compensate the reactive power. The introduction of three-level technology has greatly promoted the development of APF. Compared with the traditional two-level, it has great application advantage. Its structure characteristics make it difficult to adopt suitable modulation algorithm and control DC side neutral-point voltage balance. For this reason, the in-depth exploration and research have been carried on by many scholars. The research and develop- ment of three-level diode neutral-point clamped （ NPC ） say. active power filter are summarized in this es-
