During the reporting period, scientific research work was carried out in accordance with the corresponding stage of the work plan for 2022. A comprehensive assessment of research methods was carried out and the technical means for performing the work were determined, taking into account the current state of development. A passive filter scheme has been developed, in which, due to a change in the structure, the value of the voltage on the load is limited in operating modes close to idling, which contributes to the reliable operation of the passive filter in a wide range of load changes. A comparative analysis of the developed device with known analogues shows that the filter is distinguished by the presence of new connections, which consist in the appropriate connection of circuit elements with each other and the introduction of new elements, namely: a current relay, a contactor, the second group of capacitors of a capacitor bank. The new elements and connections of this filter are designed for their practical implementation with the achievement of a new technical result, namely, the improvement of filtering properties and expansion of the filter's functionality due to the appropriate combination of filter elements and changes in the capacity of the capacitor bank in accordance with urgent technical needs. In addition, changing the connection scheme of the capacitor of the resonance branch of the filter significantly improves the filtering properties, which in turn allows reducing the size of the filter and its cost. In view of the above, effective use of the proposed filter is assumed under the conditions of a limited voltage level on the load and the need to have the functional ability to adapt the filter parameters depending on the spectrum of harmonics generated by the load.
