中文摘要:
      有源功率因数校正器(APFC)的应用场合日益增多,采用两级或多级并联交错APFC可以有效地降低电流纹波,减小电感尺寸,更好地应用于大功率场合。文中在首先描述两级交错并联APFC电路结构和工作原理的基础上,提出了两级均流的控制方法及其数字实现的基本方法。设计了基于dsPICDSC的数字实现方案,采用Matlab/Simulink对整个APFC系统进行仿真分析后,对该方案进行了实验验证。结果表明数字实现并联交错APFC是可行的,并且具有很好的纹波抑制效果和均流特性。
英文摘要:
      Active power factor correction(APFC) is used in an increasing number of applications.Two-stage or multi-stage interleaved APFC which can effectively reduce the current ripple and inductor size,is better used in high power applications.The paper firstly described the circuit structure and working principle of two-stage interleaved APFC,then proposed a control method and its digital implementation for load balance.Design a digital implementation of APFC based on dsPIC DSC,and use Matlab/Simulink to simulate t...
