How To Test an IGBT

Remember not to touch an IGBT or MOSFET with your hands due to potential damage from static!!!!

Thank you Sir, Extremely good video and very patiently expressed on how to test IGBT. I have seen this video almost 5 times as I am preparing for my marine ETO's oral examination and this video has helped me a lot. So my special thanks to you. Also I like your dog very much, reminds me of my darling Labrador Justus.

Thank you for explaining this so well for electrical ignorant ppl like me. I’ve spent 48 hours trying to figure these things out on my welding machine. At least I can test it properly now and understand what’s wrong if anything there. Maybe if someone sees this… primeweld TIG 225 made a pop noise from the ground clamp. Probably bad ground.. no burn marks inside the machine anywhere at all. Did not trip the initial mini breaker on the machine rated 60A. Did not trip the breaker in my building rated 40A. Did however trip the breaker in my main supply breaker box outside about 50 yards away from the building, supplying the building separately from my house….this breaker is rated 50A. There is no other appliances or lights connected to the 220 breaker in my building that the welder was hooked to but there were several other things running inside the building. There was “corrosion?” on the big boy breaker outside… the huge circuit breaker that power from the poles comes to first. Anyway, now the welder won’t even turn on… nothing. I hook my plasma cutter up to the power supply and seems to work fine. Power supply seems ok. Mini breaker on the welder allows power to pass through when switched on… I guess that means it’s ok too? Any help would be much appreciated. I dare not take it to a repair store and not know what’s wrong with it beforehand. Amazing welder other than this btw 🤗. I have a feeling it’s not even the welding machine’s fault that it’s broke. Oh the welder is like I said primeweld TIG 225 AC/DC P … not the newer version TIG 225X, but I’m like 80% sure the only difference there is the pedal it come with.

Like MOSFETs, it's usually the lower side one that's blown or short due to the back EMF from the inductive load.

Good afternoon engineer. I loved your video. Thanks to him I was able to get out of a problem with a Haas brand module., 🎩

Very good video. Great tip to ground out the trigger gate and emitter to prevent false reading of bad power circuit.
