Rezumat

Novel three-stage algorithm of synchronous PWM control of five-phase inverter in the zone of overmodulation has been proposed and investigated. It provides smooth transition from linear modulation range to the ten-step operation mode of five-phase system at the maximum fundamental frequency, with full DC-bus voltage utilization. Simulations give the behavior of five-phase system during synchronous PWM control in the zone of overmodulation.

Este elaborat şi cercetat un algoritm original de reglare sincronă prin trei etape a invertorului cu cinci faze în zonă de supramodulare, ce asigură trecerea lentă de la zonă modulării lineare la tensiunea fazale de ieşire cu zece trepte a frecvenţei maximale de ieşire a invertorului. Sunt enumărate rezultatele modelarii regimurilor de bază ale funcţionării sistemelor de conversie cincifazate în zonă frecvenţelor majorate de ieşire.

Разработан и исследован оригинальный алгоритм синхронного трехэтапного регулирования пятифазного инвертора в зоне сверхмодуляции, обеспечивающий плавный переход от зоны линейной модуляции к десятиступенчатому выходному фазному напряжению на максимальной выходной частоте инвертора. Приведены результаты моделирования базовых режимов работы пятифазной преобразовательной системы в зоне повышенных выходных частот.
