Abstract

Многозонный преобразователь постоянного тока в переменный, содержащий источник тока и 3-фазную мостовую схему, в которой каждое плечо моста выполнено из 2 групп n-последовательно включенных управляемых однонаправленных вентилей, отличающийся тем, что к точкам соединения которых в каждое плечо моста вводят дополнительно две группы неуправляемых вентилей, причем одну группу n управляемых вентилей подключают катодом крайнего вентиля к нагрузке, а анодом другого крайнего вентиля группы - к «+» источника тока, вторую группу управляемых вентилей подключают анодом крайнего вентиля к нагрузке, а катодом - к «-» источника тока, при этом между анодами последовательно включенных управляемых вентилей первой группы и нагрузкой включают диоды первой дополнительной группы, катодами к нагрузке, аналогично, между катодами управляемых вентилей второй группы и нагрузкой также включают диоды второй дополнительной группы, анодами к нагрузке.A multi-zone DC to AC converter containing a current source and a 3-phase bridge circuit in which each bridge arm is made up of 2 groups of n-series connected controlled unidirectional valves, characterized in that two additional groups are introduced into the connection points of each bridge arm uncontrolled gates, and one group of n controlled gates is connected by the cathode of the extreme gate to the load, and the anode of the other extreme gate of the group is connected to the "+" current source, the second group of controlled gates it is connected with the anode of the extreme valve to the load, and the cathode is connected to the “-” of the current source, while the diodes of the first additional group are connected between the anodes of the series-controlled controlled valves of the first group and the cathodes are connected to the load, similarly, between the cathodes of the second group of controlled valves and the load also include diodes of the second additional group, anodes to the load.
