Yeah,, double post, sorry, sorry.
I have found the data sheet for the IGBTs I want to use here , It says that for Continuous Collector Current, it can withstand 55a and max forward current can withstand 220A!

Just be sure if you use a TO-247 or similar package (as opposed to the SOT-227 types with much more thermal mass and lower thermal impedance) that you ensure proper heatsinking AS WELL AS proper thermal path from the component to ground.
Also, buy lots of them, as you'll smoke much more of these trying to get working that a larger IGBT.

yeah, they are the TO-47 type, so they will be fan cooled and have medium size heat sinks each, while having minimum resistance between them. thank you EsterVoltResearch, more questions for you all later, plasma.

Okay, Plasma, I'll bite.
Lets assume you have built an electronic circuit before. Lets say that you built a simple light bulb circuit with a battery.
The red wire from your positive side went to feed the bulb. The black lead coming out of the bulb you fed back to the negative side of the battery. The black lead was your "Ground".
When you build a more complex electrical circuit, with both positive and negative voltages, your ground would be your zero volt reference.
Or, some good reading would be here. and here. . .
I would recommend that if you don't know what "ground" is, then it would be beneficial to learn a few basics of electricity before attempting to build a tesla coil.
I would go get a book, one of the best is the ARRL handbook.
another good read is. . . .
And still better is. . .
Don't take this the wrong way, but really, learn the basics.

Which IGBT?
