A new approach to expanding the suppression band and reducing the power losses in a parallel active filter by incorporating an additional corrective linear link into its structure, taking into account a delay in the interface filter, and minimizing the switching frequency of inverter power keys is developed. An algorithm of controlling the corrective link that allows increasing the performance of AF and improving the suppression of higher harmonics is proposed.
