摘要
将有源功率因数校正技术运用到基于交流-直流-交流拓扑结构的变压变频单相正弦波发生器,改善其输入端功率因数,以求达到单位功率因数水平。文中描述了控制方法,建立了等效模型。通过Matlab/simulink仿真,验证了方案可行性。
In order to obtain an unity power factor,the active power factor correction technology is used to improve input power factor of a single-phase sine wave generator of variable voltage and variable frequency,which is based on AC-DC-AC topological structure.This paper describes the control method,and establishes the equivalent model.The simulation using Matlab/simulink shows the feasibility of the scheme.
