You ever fry three $35 mosfets in one day?
Bleh.

Ouch. I've blown some expensive kit before, and it always stings. :(
@zetasyanthis this was on a project for work so it's not our money but still that's just. Bleh.
I hate how expensive these are and i wish we could find something that works just as well for not as much money

Oh, whether it's personal or work stuff, it still stings. Sometimes literally if you blow a part badly enough. XD
@zetasyanthis No, it was a different part entirely--one that survived--that we burned our finger on today.

Mmm. You're reminding me of good times, if occasionally painful ones. We used to have a big honking linear power supply we called the "Tracebreaker" for when an intern's board had a short to ground and they couldn't figure out why. :)
(As I recall, it was like a 15V, 30A absolute beast of a thing. Weighed a freaking ton.)
@zetasyanthis We get to use a 2000 V, 2 A power supply at work. It's a pretty scary thing to work with.

@zetasyanthis In general, when you need to get out the 3φ plug to power something, it's going to be a pretty scary thing to work with.

Oh yeah, definitely. I... don't know how it happened, but even 208V three phase is small to me today, and single phase a joke.
I've somehow involved in factory infrastructure (for testing lots and lots of servers), and to give you a wince, we're looking at upgrading our feed, as 7.5MVA isn't enough anymore...
It makes any breakers in my apartment feel like cheap toys. ;_;
SiC MOSFETs have an unpleasant combination of characteristics: very sensitive to even a tiny bit of overvoltage, very expensive, very fast (thus generating ringing pretty easily that can go over the rated voltage), and very much the only thing that can work in this circuit.
