摘要
现在的电力系统中大量使用整流器给人们解决了很多问题,但又引入了许多新问题,其中最严重的就是给电网带来谐波,谐波电流使电网的功率因数下降,严重时造成电网电压畸变。本文以基于隔离式Cuk变换器的APFC电路为研究对象,系统分析了隔离式Cuk电路拓扑结构和工作过程,提出了带隔离的Cuk型APFC电路结构的设计,并在MATLAB的Simulink环境下对整体电路建立了仿真模型,得出设计的电路是可行的。
In what is now the electric power system,the extensive use of rectifier to solve the problem,they introduced many new problems,which the most serious is to the power grid harmonic. And harmonic current enables grid power to decrease a serious distortion of the voltage. The isolated Cuk Converter APFC circuit is based on the research object,systematic analysis of the isolated Cuk circuit topological structure and working process,with isolated Cuk type APFC circuit structure design is presented,and in the MATLAB Simulink environment the whole circuit has established simulation model,in that the circuit design is feasible.
