摘要
有源功率因数校正技术对解决电源污染问题有着重要意义。本文引入建模分析法和状态空间法研究一种平均电流控制模式的Boost型功率因数校正技术,分析Boost变换器各个环节的电压、电流的变化情况,推导其状态方程,建立了Boost变换器的MATLAB仿真模型,并利用UC3854控制芯片,设计出一个基于平均电流控制模式的功率因数校正实验装置。仿真与实验结果的一致性表明该模型是有效的。
The technology of APFC is very important to solve the problem of power pollution. The modeling analysis and state space method were introduced for Boost type PFC technology of ACM.The changes of voltage and current of all aspects of Boost converter were analyzed,then the equation of state was derived,so a MATLAB simulation model of Boost converter was established,and a power factor correction apparatus based on ACM using UC3854 was designed in the paper.The consistency of simulation and experimental results showed that the model was effective.
