Abstract—Active filters are widely used in power system for reactive power compensation and voltage/
current harmonic elimination. Harmonic contents of the source current has been calculated and
compared for the different cases to demonstrate the influence of harmonic extraction circuit on
the harmonic compensation characteristic of the shunt active power filter. In this paper, a fuzzy
logic controlled, three-phase shunt active filter is used to improve power quality by compensating
current harmonics which is required by a nonlinear load. However, when the LC-HAPF is
performing dynamic reactive power compensation, this dc-link voltage control scheme will
influence the reactive power compensation, and thus, makes the LC-HAPF lack of success to
carry out dynamic reactive power compensation. In this paper, a novel dc-link voltage control
scheme for LC-HAPF is proposed so that the dc-link voltage control with start-up self-charging
process can be obtained as well as providing dynamic reactive power compensation.
Representative simulation and experimental results of the three-phase four-wire center-spilt
LC-HAPF are presented to verify all deductions, and also show the effectiveness of the proposed
dc-link voltage control scheme in dynamic reactive power compensation.
