I am currently designing a 5.5KW 3 phase induction motor soft starter board for my Project. I have developed it half way but I am facing problem in designing a pulse amplifier circuit for SCR gating circuit.

I have attached the simulation results from output of the comparator which is showing the soft starting and soft stopping pulses which are to be fed to the pulse amplifier.

How could I use these pulses to trigger the SCRs gates?
