Hello Academia,
I've been trying to get information regarding these configuraitons in a 3 phase transformer. The first is a dual secondary consisting of a wye output and delta output. Both feed separate 3 phase bridges, which outputs are connected in parallel.
The second is a Wye output, which each leg feeds 3 more series windings, which are located on the adjacent core (phase shifted) on the same transformer, with only one 3 phase bridge for the output
I see there is a zigzag simulink but can't seem to get that loaded...
My question is, are these essentially identical in operation, or is the dual secondary what I should be using? (due to better harmonic rejection)
Thanks,
Bryan
