APPLICATION OF THE DIGITAL FILTERING METHOD FOR CORRECTING THE CURRENT WAVEFORM IN NETWORKS WITH ALTERNATIVE POWER SOURCES

<jats:p>It is proposed to use a digital notch filter to form a reference compensation signal for a parallel single-phase active current harmonic filter, which is simple and flexible compared to known methods in its technical implementation. Mathematical modelling of the digital filter was performed in Matlab, and the results of the practical implementation of the filter-compensating device are presented, confirming the main theoretical results of the study.
