ENERGY AMPLIFICATION

Well, they handle HV better, but the on resistance is high. That is a problem if the aim is to discharge a cap into a very low resistance primary. Most of the power will be dissipated in the transistor. You can put them in parallel, but were talking a lot to get down to very low mohm switching.

I have a few transistors that are as low as .0035 ohm typ.(Yes, 3.5mohm) Only 55v max, but 765A peak(forward and reverse)  BUK95   TO-220 case.  In Titios basic circuit there is only 24v in.

Im going to try some things with SIDAC's. The ones I have break over at about 230v and stay shorted till a min current is reached. So if a tiny cap is charged, that on period wont be long.

Thanks for the heads up Mags, I keep missing your post this is the second one Iv found reading back through the posts, we must be posting at the same time.

Maybe a mechanical short is best, definitely cheaper.

But mechanical switch burns up quick too, how to make it stronger?

Hmm.  Maybe some people think my question earlier about where to put the switching was silly.
In Daves post above, look at (K)  to the left and right of the coil. 2 separate wires as primary. Is it considered bifi? But the circuit shows the cap across the bottom ends of the 2 (K)'s and the switching at the other ends of the (K)'s. Ill check the pat to see what exactly the (K)'s are described as

Teets didnt answer that question for what ever reasons he has.

So the pic below, the first circuit is a way we have seen many times, many ways, in power supplies with normal coils. But the second circuit affords us another place to put the switching.  Dont know if there is an advantage to this yet. But there it is in the pic Dave posted. Perhaps having the 2 windings, each already precharged oppositely, affects the behavior when switched on.

Why is my cursor invisible?  Is anyone else having this issue while writing posts?

Doesn't it be the same when you close the switch? Current will flow same direction?

Eric dollard use his vibrator oscillator for 20 years and now f...d  up  and no more parts as he gave away the model years ago....
a split reed switch from a radio he says can replace the vibrator
