The inductive kick you see using spice is due to the Vsin supply turning
ON and changing from 0V to 15KVAC in a fraction of a second. change the
parameters and increase the turn-on time of the supply (Actually what you
should do is simulate the effect of slowly increasing the voltage. As if
you were using a variac.)
