The analysis of the single-phase hybrid filter of network current harmonics, which can be applied in the decentralized power system, was carried out. Mathematical modeling of such a system that feeds a bridge rectifier with a capacitive filter and the 10 kW active load was performed. A comparison of current spectrograms and current diagrams of different configurations of a hybrid filter implemented in the active part on the basis of an active corrector of the parallel type, and in the passive part - a broadband LMC filter with an additional winding Ld was carried out. The maximum current deviations from the shape of the first harmonic of the current consumption for different structures of the passive filter were determined, which is decisive for the calculation of the power part of the active filter. The installed power of the active filter was calculated, the harmonic coefficients of the current consumption of the power supply network were obtained. Ref. 11, fig. 5, table.
