Re: [EVGRAY] charging a coil like a cap

Body

Hi Mick,

"Suddenly my bench supply started clicking and feeding all its current like there was a huge load on the output rather than the x10 scope probe.  The protection diodes smoked and cracked."

Make a SCR over voltage crowbar protection (http://dfwcgi.com/approach/white-papers/51-critical-power-systems-for-crowbar-protection-of-iot-s http://dfwcgi.com/approach/white-papers/51-critical-power-systems-for-crowbar-protection-of-iot-s) to short the voltage supply and blow a fuse before smoking other semiconductors.

Regards
Ole

 Warren, 

 it would be nice to get some more tutoring from the inventor of the thing but I suppose he has lost the inclination. I think Perez is Sephardic so it could be a tribal thing.  If we had been on a private server all the info that Hector insists we never read might still be available.
 

 I plan to build an RV some day, just if you saw the stack of projects here waiting for attention you would understand my delay.
 

 I would like the source for the Chinese switches though.
 

 Those 660/1500 volt caps are a bit pricey but I need a larger cap box anyways for other work so began pricing them yesterday.
 

   Just cooked my choice little 556 pulser with the comparator pulse width adjuster the other day sending harmonics into a 1kv ferro tranny.  Was documenting harmonic frequencies with the scope and left it on a harmonic for a few minutes when the phone rang.  The unit was drawing 24volts at 10 milliamps. Suddenly my bench supply started clicking and feeding all its current like there was a huge load on the output rather than the x10 scope probe.  The protection diodes smoked and cracked.  Surprized it sinked so much power so quickly, could have been a ground loop, I have no idea what it was, very fast and like a direct short.  The diodes are on back order at Mouser.
