 The object of research is current harmonic filters as universal means of improving the electromagnetic compatibility of converting equipment devices with the power supply network. During the reporting period, scientific research work was carried out in accordance with the corresponding stage of the work plan for 2023. In particular, mathematical models were developed and simulations of new schemes of active, passive and hybrid filters were carried out, as well as their influence on the power quality indicators of the power supply network was investigated. Prototypes of passive and active filters with a capacity of 5 kW were manufactured to study their operation from the power supply network to improve the electromagnetic compatibility of converting equipment devices. A new three-phase current harmonic filter has been developed, having a magnetic core with one or more non-magnetic gaps, which includes three rods, each rod corresponding to one of the three phases of the power supply system, and two yokes placed at the ends of these rods, which close their magnetic fluxes. The operation of such a filter without and with the connection of an additional capacitor was analyzed and the load characteristics were obtained for both cases, as well as the dependence of the change in the current harmonic ratio (THDI) on the load power of the PH. Thus, it was found that with the inclusion of an additional capacitor in the presence of sensitive equipment in the load, which does not allow the voltage to exceed 600 V, its reliable and high-quality power supply is ensured. As the next step in the study of this filter, the authors plan to optimize its parameters for use in a hybrid structure as part of research work. The obtained results have scientific and practical value, meet international standards and can be used to improve the indicators of electromagnetic compatibility of converting equipment devices with an industrial power supply network of limited capacity.
