| 摘 要： | 随着电力电子技术的发展，各种电力电子设备应用于电网，给电网带来谐波问题，各种谐波滤波器也应运而生，但这只是一种先污染后治理的被动办法，APFC是一种主动的办法，它用于开关电源前级整流器，输入电流为正弦波，不对电网产生污染。全文围绕一种新颖的基于隔离型Cuk变换器的有源功率因数校正电路的设计，从Cuk变换器的基本单元入手，分析了Cuk变换器的工作原理，在此基础上，确定了基于隔离型Cuk变换器APFC电路的基本拓扑。

| Abstract: | With the deveiopment of power electronics, power electronic equipment used in a variety of network, brought to power harmonic problems, all kinds of harmonic filters have emerged, but this is only a passive treatment after pollution measures, APFC is a proactive approach, before the class is used to switch power rectifier, input current is sine wave, and do not pollute the power grid. Full Text based around a new Isolated Cuk converter active power factor correction circuit design. From the Cuk converter basic unit proceed with, analyzed Cuk converter＇s principle of work, on the basis of this, is determined based on the isolated Cuk converter APFC circuit topology. |
