Considering that the total primary winding consists of n constituent primary windings, each of which includes one MIO 1200-33E10 module with the corresponding driver as IGBT switch, at n = 25 the commutators of the total primary winding are able to pass the current [I.
The voltage spikes are generated in the transformer primary winding during the second cycle.
End effects are therefore caused only by the finite length of the primary windings but not by the iron core.
