摘    要:设计了一种单周控制的三相三线制有源电力滤波器,该滤波器工作时无需检测三相负载电流和三相输入电压,无需进行繁琐的参考电流、无功电流和谐波电流计算;只需检测两相电源电流和直流侧电容电压,通过简单计算就可直接求出每个开关周期内各开关的占空比.给出了该滤波器的控制方程,并对其进行了仿真研究,仿真结果表明新设计的滤波器能有效补偿谐波和无功电流,抑制负载不对称。

关 键 词:单周控制  三相三线制  有源电力滤波器

Abstract:A three-phase three-wire active power filter(APF),controlled by one cycle controller is devised.The measured quantities of three-phase load currents and three-phase input voltages,and the complicated calculations of the reference current,the harmonics and reactive current components,are eliminated.The duty ratios of switches in each switching cycle can be directly obtained by simple calculation using two phases source currents and dc bus capacitor voltage.The control equations and simulation results are also presented in this paper.The simulation results verify that this APF can effectively compensate the harmonics,reactive currents and loads dissymmetry.
Keywords:one cycle control  three-phase three-wire  active power filter
