摘要
传统的模拟控制技术有许多不可克服的缺点,采用数字控制技术的PFC具有显著的优点。文中主要从理论上分析和研究了数字控制BoostPFC电路的工作原理和关键技术,讨论了采用数字信号处理器(DSP)作为控制核心时PFC主电路参数的选择。最后,在Matlab/Simulink中建立该数字控制PFC系统模型并仿真得到了较理想的波形。
Compared with the traditional analog PFC＇s insuperability shortcoming, digital control of PFC has prominent advantages. Studies the work principle and key technology of the Boost PFC circuit in theory, how to choice parameters of PFC main circuit using DSP as control center is described. Lastly, simulate this digital PFC system in Matlab/Simulink and gain the preferable waves.
