hello all, i'm new here, and i'm currently investigating current harmonics on the primary side of the transformer in a typical 12/24 pulse rectifier system.
i wish to implement 12 pulse first, at -7.5 and 22.5 degrees (for 30 degree phase shift) so that it is easily extendable to 24 pulse (-7.5, +7.5, -22.5, +22.5)
the DC link output of a 12 pulse rectifier should follow:
(2)(1.35)(V line-to-line of output of secondary of transformer)
so for a 2.2kv output of transformer i should expect (2)(1.35)(2200) = 5940.
but my simulink shows a 1000V more (around 7000V)
can anyone shed light on this?
I'm sure my connections are correct in simulink.
