Предмет изобретени Subject invention

Трехфазный самовозбуждающийс  инвертор , содержащий трехфазный мост транзисторов и три выходных трансформатора с дополнительными обмотками обратной св зи, отличающийс  тем, что, с целью упрощени , первичные обмотки трансформаторов соединены по схеме звезда, а обмотки обратной св зи в каждой фазе соединены с входом транзисторов данной фазы.A three-phase self-exciting inverter containing a three-phase transistor bridge and three output transformers with additional feedback windings, characterized in that, for the purpose of simplification, the primary windings of the transformers are connected in a star circuit, and the feedback windings in each phase are connected to the input transistors of this phase .
