The hybrid active power filter，which combines passive filter and active power filter，has both respective merits, and is an important developing trend of filtering device. The hybrid active power filter can reduce the capacity of active power filter effectively and is more suitable for the engineering application for high voltage nonlinear loads. The compensation performance of hybrid active power filter is analyzed by estimating the effect of different active power filter gain and parameters change. Then，a conclusion has been obtained that the harmonic attenuation rate is insensitive to the variation of passive parameters when the active power filter with an enough feedback gain is combined. Finally，the feasibility and validity of proposed scheme is verified by Simulation using Matlab and a hybrid shunt active power filter prototype. Index Terms:Current harmonics compensation，active power filter，passive filter， generalized integrators. I .INTRODUCTION In the development of power electronics brings convenience to energy conversion and utilization and also causes power quality problems. As one of the key technologies in combating power grid pollution and improving the power quality， active power filter (APF) has become a new research emphasis in power electronics tcchnology[l]-[5]. Because of high initial cost，the further application of active power filter is restricted. The HAPF(Hybrid Active Power Filter)，combination of APF and passive filter (PF)，can reduce the capacity of Affectively and is more suitable for the engineering application of APF for high voltage nonlinear loads. Traditionally，Passive filter has been used to elimin
