摘要:
Abstract— This paper describes the proposed active power
filter (APF) with a modified output inverter. When the value of
load current changes rapidly, the APF transient response is too
slow the line current suffers from dynamic distortion. This
distortion causes an increase of harmonic content in the line
current, which is dependent on a time constant. The APF control
current dynamics is dependent on the inverter output time
constant consisting of APF output inductance and resultant
impedance of load and mains. According to this modification the
APF dynamics are improved. The Matlab simulation results of
the modified APF are also presented in the paper.
