并联型有源电力滤波器(PAPF)直流侧电容是其正常运行所必需的能量储存设备，其大小直接影响到 PAPF 的谐波补偿效果。针对单相 PAPF 直流侧电容与电压波动关系这一问题，通过瞬时功率流分析得到对直流侧电压波动有影响的功率分量，并在特定的负载条件下对该功率分量进行积分得到电容能量波动精确值，推导出在一定补偿容量和电容电压波动幅值下电容容量的数值。仿真和实验结果证实了该方法的正确性和可行性。

As energy storage device,the DC side capacitor is required for the normal operation of the parallel active power filter (PAPF),which directly affects the harmonic compensation effect of PAPF.Aiming at the problem of the relationship between DC side capacitor of single-phase PAPF and voltage fluctuation,an approach is presented according the analysis of power components which have influence on the fluctuation of DC voltage through the instantaneous power flow.And the capacitor energy fluctuation precision value is obtained by integrating the power components under the specific load conditions.The capacitance under a certain compensation capacity and capacitor voltage fluctuation amplitude value are derived.Simulation and experiment results confirm the validity and feasibility of the method.
