And he uses that same looped music in every single one of his videos. Oh, and the guy is Vietnamese, not American, making the channel name perplexing, too.

Vietnam. The same place those fake "restoration" videos come from...

No no no no. This is how you handle large current

switches over 1MW and costs around 120 EUR @ single piece. The bang per buck is insane in my opinion.

Well, I didn't really consider this metric. But yeah, if you have to get the same switching characteristics with a number of cascaded and paralleled MOSFETs, I guess this makes sense.
Just comparing some IXYS MOSFET I mentioned (600V/170A) which costs about 30 euros per one. By your metric, that would be about 111 kW. So, by this metric, the ratio "power" over cost is about 2.25 in favor of the IGBT. ;D
MadTux:
What's the point? I don't get it.
Youtube 2020, solder some fricking MOSFETs into a big package, make 17min video about it and collect youtube cash?
