The paper reviews the features of the synchronization system for three-phase shunt active power filters.
It suggests an improved more stable design of a synchronization system with. The synchronization system has been improved by introducing bandpass filters in order to filter the input signals of a conventional phase-locked loop synchronization system. The design of the second-order infinite impulse response bandpass filter has been elaborated. The simulation of the three-phase shunt active power filter with the proposed synchronization system was carried out. The simulation results were verified by the laboratory prototype of a three-phase active power filter.
