Re: [TCML] Kick back voltage

No, Matt,

You want an ordinary 1N4007 silicon diode reversed biased across the output. The forward voltage across MWO diodes is in the range of 35 to 50 volts, which wouldn't give the power supply much protection.

However, such a diode won't protect against transients relative to ground. Some combination of resistors and capacitors might give a bit of protection, but in the long run, lead acid batteries are your best bet.

Switch mode supplies are delicate creatures, unsuited to the sort of application you are proposing. You need a good old vacuum tube supply. That would tolerate massive transients better than anything made of silicon.

I got a new 5V DC 20amp switching supply. If i put a 12KV (or 2) oven diode backwards across the +/- will that give me some spike protection?

I went to my local ax man today someone sold them a tesla coil but they wouldnt sell it to me :(

Thanks for any suggestions.
