【摘要】 本文在分析有源滤波器基本原理的基础上建立了并联型有源滤波器的数学模型。针对电网电压波动对有源滤波器工作性能的影响进行了具体的分析,并提出了利用电网电压前馈的控制方式来有效地抑制电网电压波动对APF的影响。最后运用MATLAB对此方法进行了仿真验证。更多还原

【Abstract】 This paper proposes the mathematical model of shunt active power filter(APF)on the basis of the principle of APF.The influence on APF caused by the voltage fluctuating is analyzed,and also proposes a voltage feed-forward control method to effectively restrain the influence on APF caused by the voltage fluctuating.At last,the simulation results validates the method.更多还原
