基于MATLAB的有源功率因数校正器设计

The Design of APFC Based on MATLAB

APFC在小功率的特种开关电源系统中应用日益广泛,在许多特种电源系统中,如何结合整个控制系统设计满足要求的APFC已成为实际应用中必须面对的问题。本文简述了APFC的控制原理,给出了利用MATLAB进行电压环、电流环及前馈电压环节的设计校正过程,最后用SIMULINK建立了一个AFPC仿真电路,给出了仿真波形。

The technology of APFC is using widely in the system of power electronic devices.In many applications how to design a APFC satisfied with the whole power supply system has already become a task that we must faced .In the paper we describled simply the principle of APFC and adjusted the parameters of back voltage segment, current segment and forward voltage segment with MATLAB. We creat a motile of APFC using SIMULINK,and list it＇s key waves.
