      <abstract xml:lang="ru">
        <p>Рассмотрены структуры систем с высоковольтными каскадными преобразователями частоты, содержащими многообмоточные трансформаторы и низковольтные маломощные блоки преобразования, соединенные по выходу последовательно в каждой фазе нагрузки. Низковольтные блоки содержат трехфазные диодные или активные выпрямители, конденсаторные фильтры выпрямленных напряжений, однофазные автономные инверторы напряжения и устройства отключения блоков в частичных режимах (при выходе из строя и отключении части блоков). Определены возможности работы каскадных преобразователей, даны уравнения для корректировки заданий блокам в частичных режимах, предложены таблицы корректировки заданий с оценками достижимых характеристик нагрузки. Приведены результаты экспериментов на макете мощной установки с каскадным преобразователем частоты, подтверждающие возможности обеспечения симметрии токов нагрузки при отключении части блоков и несимметрии схемы.</p>

        <p>The structures of systems with high-voltage cascade frequency converters containing multi-winding transformers and low-voltage low-power converters connected in series at each output phase of the load are considered. Low-voltage blocks contain three-phase diode or active rectifiers, DC capacitor filters, single-phase stand-alone voltage inverters and block disconnecting devices in partial modes (in case of failure when part of the blocks are disconnected). The possibilities of operation of cascade converters are determined, equations for correcting tasks to units in partial modes are given, tables of correction of tasks with estimates of achievable load characteristics are proposed. The results of experiments on the model of a powerful installation with a cascade frequency converter are presented, confirming the possibility of ensuring the symmetry of the load currents when disconnecting part of the blocks and the asymmetry of the circuit.</p>
