Kapanadze Cousin - DALLY FREE ENERGY

[NickZ]

High frequency diodes have low efficiency and large losses at equivalent noise spectrum above megahertz.
There is a special POWER HF  arsenide-gallium diodes, but such diodes are not sold on the market, or are very expensive.
In addition, it is necessary to match the source and load impedances. Usually this makes a special transformer.
Probably a suitable chip for measuring energy of chaotic pulses, but not high frequency:https://www.analog.com/media/en/technical-documentation/data-sheets/2947fa.pdf

   Sergh:
   If you are talking about the diodes used on the full diode bridge at the grenade's output, I used the U1560 high speed diodes, which don't get hot like some others do. There is a lot of power going through those diodes, and if the right diode is not used, the rectified voltage at the output will be lower, and any improper diodes will burn up. The U1560 do fine, without heating up, but the U1560 are higher voltage ones, and are better yet. So, the U1560 are the ones that I would recommended.

U1560 U = Ultra fast 60 ns (35), 15 = 15 amp 60 = 600v

the low forward voltage drop Average now you can get 1200v Ultrafast
but I'm sure Surgh can quote some better avalanche types

As with all modulated signal frequency RF needs demodulating down to a more usable frequency by heterodyning !!
only a reprobate/novice would try rectifying or using UHF RF as is as a power sauce directly and ignore phase shifting etc.
As I'm sure it's a puzzle where Mr. Henry T  Morey and others like D Smith obtained his devices you refer to from.

It is used mainly because it is easier to amplify a lower frequency narrowband signal.
In addition, a mixer is required. A mixer is a non-linear element for mixing frequencies.
Without it, the frequencies will not mix. The mixer is made with diodes or transistors. Again the diodes...

This diode has a reverse recovery time of 60 ns. But I think that it is inefficient to use it as a power rectifier above 100 - 200 kHz due to the transition capacity. Diodes with a reverse recovery time of 18 ns, HFA08TA60CPBF,  as power rectifiers <1 MHz. But super-fast diodes do not quite match the power diodes due to the higher forward voltage  at maximum current. Above 1 MHz, as power rectifiers, Schottky diodes are mainly used for not too big currents and low voltages. Or new SiC Schottky Diodes.

What do you think about such rare gallium arsenide power diodes from the Soviet Union times?
225 volts, 1 amp, 20 picofarads, reverse recovery 100 picoseconds (0.1 ns ), working frequency of rectification up to 1 GHz :

Probably have similar Western diodes. I have no idea where such power diodes could be used in ordinary electronics ..

What is the point of rectifying high-frequency voltage? Bulbs glow at high frequency as well as at low. The heat is the same. Only for powering the device itself?

   Sergh:   The point is that in order to have a use able feed back circuit, in order to self run, and not just light some bulbs, those diodes are used by me to rectify the HV and HV to be acceptable as an input source to the 24v power supply, which is the feed back circuit PS going back to the input.
   I am not trying to reinvent the circuit, and these diodes work for me.  You can chose what ever diodes that you think work better. Or no diodes or rectifier at all, if you think that that would be better, yet.
   I try follow the schematic, which shows the 12R06 are the normally recommended diodes for that purpose, but the 1560 diode should work just as well up to the needed 2MHz. My Kacher runs at around 1MHz, and my induction circuit runs at around 1.5KHz. And the 1530 diodes seam to do the job to rectify the needed voltages and currents, without heating up.

Anyway, if your really stuck you can wire up any MOSFET as any fast diode or MOSFET can operate  with any of the mos fets original limits !    so there.

Nickz  My Kacher runs at around 1MHz, and my induction circuit runs at around 1.5KHz. And the 1530 diodes seam to do the job to rectify the needed voltages and currents, without heating up.

'Can you get your Katcher up to 1.5mhz' it would then be a lot happier if your induction winding was 15khz
