I am looking to make a variable 0-700v 100 amp supply with a 3 phase 480vac input using a Zero Voltage switching method, A 0-5 v input, and gate drivers in one IC. I have researched methods and going to use 6 scr's, A line filter, Large cap, and isolation for the gate drive. We already use these for DC drives but firing boards are complex and not in my scope for this project. Can you suggest single IC's(or three) that handle this or is this such a thing that is not made. I realize support circuitry will be needed as you cannot put 700 volts into any chip. Any suggestions will be appreciated.
