Jeez, dude! Read a book or something!
No, you can not use an electrolytic cap for a snubber.
Analyze the circuit, and learn why.
Good Luck! (You're going to need a lot of it, at this rate.) Rich

This is in regards to my IGBT based TIG welder DC -> AC inverter project for a 200A welding machine.
Subject says it all. My new calculations suggest that I can have a snubber circuit with 8,000 uF of capacitance rated for
200V. That would limit voltage in my system to under 200V.Based on the following assumption:
Reactor inductance: 1.85 mH Highest continuous current 350 A Continuous Voltage 30V
(note that open circuit voltage is 85 V, but the current at that voltage is 0).
I already have 200V, 10,000 uF capacitors, in fact more than one. They are electrolytic. Also, I got myself some power diodes for the D part of RCD. I will parallel them.
