hello ,

I've asked a question called "3phase transformer and bridge rectifier" in which I asked about connecting 2 rectifiers from one transformer , and if this is possible , now I have a different question in the same topic , can I connect the ground outputs of the two rectifiers ?

this is the ct I have

but when I tried this connection , the controller burned and the IGBT gat driver in one of the two channels burned , what is wrong with this connection ?

thanks

 

The same thing as in the other thread, is the simple answer.
