К ключевым параметрам фильтров относятся динамические потери мощности в вентилях, которые оказывают влияние на КПД преобразователя и соответственно определяют целесообразность применения указанных фильтров в каждой конкретной ситуации. Наряду с решением задачи обеспечения надлежащего качества электроэнергии в точках общего подключения к сети особую актуальность приобретает снижение динамических потерь в вентилях. Цель исследования – повышение эффективности активной фильтрации в части снижения динамических потерь в вентилях при обеспечении высокого качества напряжений в точках общего подключения к сети и потребляемых из сети токов. Для ее достижения предложено совместно использовать двухконверторный силовой активный фильтр, работающий в режиме с различными частотами преобразования и установленными мощностями конверторов, и интерфейсный LCL-фильтр. Выполнен синтез управления преобразователем. В качестве метода используется управление на скользящих режимах. Эффективность предложенной системы оценена посредством моделирования в пакете прикладных программ MATLAB-Simulink. Результаты имитационного моделирования подтверждают возможность организации режима работы, при котором частоты преобразования и установленные мощности конверторов силовых активных фильтров различны. При этом потребляемые из сети токи и напряжения в точках общего подключения к сети имеют практически идеальную гармоническую форму. Фазовый сдвиг сетевых токов относительно соответствующих напряжений пренебрежимо мал. Показано, что организация режима работы конверторов с различными частотами преобразования и установленными мощностями позволяет существенно снизить динамические потери в ключах силовых активных фильтров.</p></abstract><trans-abstract xml:lang="en"><p>Nowadays, active power filters represent one of the most efficient means to reduce inactive power components which provides proper quality of electricity at common network connectivity points. Dynamic power losses in the valves that have a significant impact on the efficiency of the converter and, accordingly, determine the feasibility of using these filters in each specific situation, are among their key parameters. Along with the solution of the problem of ensuring the proper quality of electricity at common network connectivity points, the task of reducing dynamic losses in the valves becomes especially relevant. The purpose of the study is to increase the efficiency of active filtration in terms of reducing dynamic losses in the valves while ensuring high-quality voltages at common network connectivity points and currents consumed from the network. To achieve the goal, it is proposed to jointly use a dual-converter active power filter operating in a mode with different conversion frequencies and rated converter capacities, and an interface LCL-filter. Synthesis of converter control is performed. As a control method, the sliding mode control has been used. The efficiency of the proposed system was assessed by modeling in the MATLAB-Simulink application software package. The simulation results confirm the possibility of organizing a mode of operation in which the conversion frequencies and rated capacities of the converters of active power filters are different. In such a case, the currents and voltages consumed from the network at common network connectivity points have an almost perfect harmonic shape; and the phase shift of the network currents relative to the corresponding voltages has a negligible value. It is shown that the organization of the operating mode of converters with different conversion frequencies and rated capacities can significantly reduce the dynamic losses in the switches of active power filters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полупроводниковый преобразователь</kwd><kwd>скользящий режим</kwd><kwd>управление</kwd><kwd>высшие гармоники</kwd><kwd>электромагнитная совместимость</kwd><kwd>неактивные составляющие мощности</kwd><kwd>качество электроэнергии</kwd><kwd>LCL-фильтр</kwd></kwd-group><kwd-group xml:lang="en"><kwd>semiconductor converter</kwd><kwd>sliding mode</kwd><kwd>control</kwd><kwd>higher harmonics</kwd><kwd>electromagnetic compatibility</kwd><kwd>inactive components of power</kwd><kwd>electric power quality</kwd><kwd>LCL-filter</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Шидловский, А.
