Well, i do not have pictures because i usually do not blow my stuff up. But i have killed over 40 irfp460 mosfets, probably 10 or 20 other random mosfets, I purposely blew a microwave diode up by shorting it across a 12 volt battery, broken many flyback cores, fried 2 or 3 mots, blown up a few capacitors, over 50 ne555's(more like 100's), and just today i blew up two regulated power supplies. There has been much more stuff i have fried, but i cannot think as it is like 1am right now :).

I don't have any pics of the things I have killed because none of the failures were all that amazing. I have killed 2 IRFP250Ns in my ZVS flyback driver. 3-4 555s in my old iggy coil driver (that's when I decided I needed to get a better driver). One MOC because I was overrating the voltage with it resonating with 2 MOTs (connected so it only outputted 2kV). And one random MOSFET the first time I made the ZVS flyback driver (Vds rating was only 60V...)

Gah, bad I made no picture of the fun I had in the lab. I had to test an old Soviet AFC analizer (yeah-yeah, in Soviet Russia, the caps blow you :D). Of course I hit the switch with my very common and favorite "And now it's gonna go crraaack!" quote (came from the term of a thyristor invertor shoot-through lockup, which here is translated almost the same as "crack-through", so apparently we invented a term of "crack-out", which, of course, is a result of a transistor invertor shoot-through when they crack sending parts of the casing flying around). "Nah, why?" - my co-worker replied. The tube lighted up, I could see traces and things just felt even not to go wrong, excepting the trace slowly moving down (old capacitor leakage as I guess now) and some weird smell I thought to be dust etc (that device came from 60th iirc). After my second "How to get the goddamn trace back?!" question (the machine ignored my attempts to do it with the resistor handles) however the answer came loud and (un)clear - the blast was so loud it even rang in my ears for a while (couldn't scare me as I'm always ready for alike things). A bright shotgun-style flash, weird dense smoke with an even a bit enjoyable smell, a wasted fuse - and it's time to watch the aftermath. Was a sight to see - the floor had an oil mark of a few squares (the pattern of the ventilation grate it all was shot out through), and inside the box the huge el capacitor hull stood like a shotgun shell, with all the fill scattered all around. The biggest cap blow I ever seen!

I decided to not risk wrecking the rest of the case from another cap exploding, I was lucky it was only the end piece of plastic, a few hrs and some plastic and it should fix up fine. Instead, I ordered the real deal from general atomics energy products (once maxwel I believe). A big pulse cap, 11kv at 525 uF, 125,000 amp rating. It just came into Australia this week after patiently waiting for the last 14 or so weeks for it to be made, should have it on my doorstep in this comming week. 100 kg of capacitor, very excited .

Re: pics of blown Electronics.
Tom540, Fri Nov 28 2008, 10:23AM


Just curious, How much was it? General Atomics is right next door from where I work. I was thinking of getting a few things from them but everything looks so expensive so I never got any quotes.

Re: pics of blown Electronics.
Neil, Fri Nov 28 2008, 11:19AM


It was $9,913 USD which was about $12,000 AUD for me with the exchange rate at the time. If you buy 4 or more, this price just about halves. Unfortunately for me, it was another $3,800 AUD to import it and pay frieght, tax etc on it so I just bought one. They seem very easy to deal with and I had no problems importing it for anyone else considering something like that.

nope, not custom, part number 33943.
These are big expensive products, it makes no sense to have them in stock. How many people but these? when these are usually bought, its larger quantity (like the navy's rail gun, they used capacitors from this company). Stock would just age them.

Re: pics of blown Electronics.
LithiumLord, Fri Dec 05 2008, 12:25AM

Was messing around an old SF generator in the lab recently. I have no idea what happened (my guess is that someone... well, I even know who actually as he was arguing with me on that topic - well, he put the three fuses in the fusebox where only one was meant to be in place - the machine is really old, so they made a three-socket fusebox where you have to set the fuse in the proper socket in order to choose between 110, 120 and 220vac mains feed), so there was something shorting out the high voltage coming from anode feed circuit, maybe a cap failed or some tube got wasted. The picture below is the double kenotrone I placed instead of the one that was placed on the output - it's filament was damaged and I thought it was a result of a mechanical shock. How wrong I was - a few seconds after I let my eye away from the new one it instantly heated up to glow and it's filament blew off before I could switch it all off. So (yes, we have a virtually unlimited storage of those) I set up the third one just to make this pic and instantly cut the power before anything goes any worse - it was a success


ps also we have a virtually infinite number of ruined mobos on the scrapyeard, so I'll try out a tiny 12v CWDRSSTC on the fets from them - non-decoupled H-bridge with tantalum bypass, the signal will be fed from a CT through a schmitt gate to four UCCs with delay circuits rigged to enable pins in order to inject some deadtime - hope those things have P-FETs as well, or I'll have to use a GDT anyway.

klugesmith, Fri Apr 23 2010, 09:33PM

From long ago in this thread:

Looks like an inherently poor design, also known as a learning experience.
Power resistors normally get very hot, and are made of stuff that can tolerate it.
This style can exceed 100 degrees C at rated power, even with free air circulation (which is blocked by the capacitors).
Plastic film capacitors don't like it hot.

[edit] Also, the smaller R's should be derated or have more room between them. Resistors get just as hot as anything else of the same size, in the same place, dissipating the same power.

not to self dont go over max volts on a meter and leave it plug in to a trasformer

Re: pics of blown Electronics.
radiotech, Mon Sept 06 2010, 06:22PM

Meters have fuses and the fuses have voltage ratings and the best meters have fuses with interrupting capacity in kiloamps on the fuse.
But the reason for these fuses and the ratings on the meters is to guarantee they wont explode if used within the rated maximum voltage .
High voltage, especially high frequency high voltage is rated with a frequency/voltage derating curve.

But all this aside, spark voltages dont care about fuses.

If you arc-over a meter whether or not it will explode into bits, in you face depends on how much energy the circuit can furnish.

I have toasted my share of expensive instruments, happily most were not mine own property. I am also aware of a Scopemeter that died whilst measuring the trend on a big SCR drive, however I was not close enough to be blamed.

I didn't take pictures of the damage, but I've had a number of mosfets explode. I had a half bridge running when I turned the juice up too high and BANG, bits of plastic shrapnel whizzed by my face. I place a shield of some sort over such things now when in the testing phase.

I recently stuck a lytic in backwards by accident and didn't notice until it vented a jet of awful smelling smoke right in my face while I was hunched over it with a scope probe. Thankfully it didn't blow the can off, I've seen that happen before.

Got a microwave oven from the electronics recycling. Externally was in good condition and no electronic component inside had any visible damage. Until i decided to get the magnetron tube out:

Sigh..

Still unclear what happened. I wasn't even pushing the damn thing and one transistor let go.

No, it was a half bridge of 60n100 IGBT'S for my SSTC. I was trying an experiment with an arduino controlling a laser from across the room aimed at the fiber input on my driver. Was running an audio mod to the coil but when the arduino reset the laser went on 100% duty killing my bridge!!

oops...

Does a battery count as a component? I have a lithium cell here which ruptured spectacularly in storage, split the casing as well.
The two cells in parallel with it were history as it decided to short out.. grr.
