摘要
有源功率因数校正器(简称APFC)现在广泛地使用在交—直电源变换电路中,以消除电力系统的谐波,提高功率因数。而在校正器中采用新的控制算法或技术,可以更好地达到消除电力系统的谐波、提高功率因数的目的。通过MATLAB/SIMULINK对所研究对象的模型进行功能仿真、验证,将验证通过的控制器模型直接自动生成微处理器目标代码,并下载到目标微处理器中进行实际控制效果的评估。这样,可以大大提高开发新的控制算法的效率。本文主要介绍基于MATLAB的有源功率因数校正系统的功能仿真、验证,从而对下一步将控制思想移植到数字信号处理器(DSP)中做好充分准备。
Active Power Factor Correction (APFC) is widely used in AC/DC converters to eliminate harmonic distortion and improve power factor. And new control strategies and techniques could enhance the goals above. By using MATLAB/SIMULINK, the function simulation and verification of the research object can be obtained. The verified model can be automatically transferred to the target microprocessor code by MATLAB to perform the control strategy in real world. Thus the efficiency to develop a new control strategy improves a lot. In this paper, the function simulation and verification of APFC system based on MATLAB is introduced. This fully prepares for future control strategies running on DSP.
