This paper centers to 3/9 stage auto-transformer with different windings per stage is controlled a 9-
stage AC to DC converter this kind of transformer has 40o stage move between the yield voltages, it is provided
from a three stage AC source with star or delta association, to utilize this sort of transformer in aviation the activity
recurrence ought to be at 400Hz notwithstanding lessen the current symphonious mutilation through a three stage
line reactor are associated after three stage AC source for this situation the current consonant twisting abatements
to esteem under 5% and it can be under 3% level by utilizing an extra concealment gadgets (Stifles) at the yield of
the converter, this autotransformer incorporates three segments each dispersed 120o electrically separated. Each
segment includes a fundamental winding and a couple of stage move windings, it is a primary component in 18 beat
converters, the multiphase amendment can be investigated by utilizing orca recreation programming, and
demonstrated the examinations between the odd stages so the 9 stages has a lower estimation of the swell factor
which is 0.763 %.
