资料介绍

随着现代电力电子技术的发展,各种电力电子设备和非线性负载被应用到电网中,使得大量的谐波注入电网。有源功率因数校正(APFC)作为一种节省电能、提高用电效率的重要技术,能够对电网中的谐波进行有效的抑制。目前,单相APFC技术己趋成熟,而三相APFC技术正成为国内外研究的热点。介绍了现有的APFC拓扑结构和基本原理,分析了各种拓扑的优缺点,并着重分析了PWM整流器的工作原理。

With the development of modem power electronics technology, a variety of power electronic devices and non-linear loads have been applied to grid, which make a large number of harmonics injected into grid. Active power factor correction ( APFC), as an important technology to save energy and improve power efficiency, can effectively suppress harmonics. At present, single-phase APFC technology has become mature and three-phase APFC technology is becoming a hot research topic at home and abroad. In this paper, the existing APFC topology and basic principles are introduced, the advantages and disadvantages of various topologies are analyzed, and the working principle of PWM rectifier is emphatically analyzed.
