Hi dear friends i use 6 thyristor as switch in 3 phase like below:
i trigger each thyristor on zero time in its phase . (i use zero crosing). it work when neutral is connect on star center .but it don't work when the neutral wire is disconnected .
what is the problem ?
i think for example in first time when thyristor's R phase is triggered because other thyristors are off it can't turn on (there is no way for flow the current in load )
but when the neutral is connected there is a way to flow current in load.
now please help me to solve the problem . how must i trigger thyristors that work circuit with out neutral wire? thanks a lot . best regards.
@i am sorry because my english isn't good.
