You are using a push-pull configuration. When one of the output mos fets is saturated, the other is cut off. Then the voltage at the drain of the cut off fet will be double of the power supply, in your case it will be around 24Volts. The Zener diodes should be a little bit over that, let's say 26 to 28Volts.

Vortex1,

Hmmm,  obviously there seems to be a flaw in my understanding of toroid cores.
I thought they always are made of ferrite and therefor are suitable for higher then 50Hz frequencies.
Apparently not,  thanks.

Now i understand the reasoning from Hoppy.

So need to know if the generator needs to run on 50/100Hz or at 4.6Khz, then we either can use the route suggested by Hoppy (commercial toroid 50Hz), or we need to build one on ferrite suitable for 4.6Khz.

But the fact that my toroid get very hot in seconds when running on 220V 50Hz still points to a defect in it.


Black_Bird,  Vortex1,

Concerning the zeners; so that's clear then why they became hot :-)  i will try higher voltage rated zeners across each MOSFET if still needed after using a good toroid.

Thanks for your comments,    Regards Itsu

Hoppy,

the Dally generator to my understanding provides 2 functions, 1 as you said a 150/200V PSU for driving the nano pulser, but 2 to drive the L1 coil with around 4.6Khz square wave pulses at this 150/200V (supposedly the double of the 2.3Khz at which hydrogen atoms spin??!!)

So therefor the generator needs to run at around 4.6Khz, and not 100/50Hz.

Correct me if i am wrong.

Regards  Itsu.

Itsu,

The winding turns look wrong to me even for a ferrite core running at 4.6Kz and the transformer symbol does indicate an iron core, so its all a bit confusing and quite possible that errors have crept into the schematic.

I'm building the Dally circuit as at least for this we have good winding info and photos for the main coil and a fairly good indication that he used an iron cored transformer. I've currently completed the inverter and nano pulser co-ax driver and will start the VCO and nano pulser next.

The toroidal is not a must. You can use an EI or EE ferrite core to make the transformer for the voltage converter. I made one, myself, using an E424215 ferrite core, and used in the primary 4+4 turns of 4 wires in parallel AWG 26, to avoid losses and the secondaries used 70 turns each AWG 26. The difference is that it operates at a much higher frequency, around 60 KHz, and, in my case, I used a simple 2 transistor converter with base feedback coils. Output in each of the 70 turn windings is around 200V. Curent input at 12v is around 1.7A. AL for the core is 4000 nH/turn2.

Its interesting that one of the inverter windings is one leg down to earth ground, which according to Dally is essential for operation. This winding is also in series with the main coil winding L1, which in turn receives induced pulses from the nano-pulser. This arrangement is similar to the concept of 'chaos' introduced to a 50Hz transformer, as is being discussed in the other thread. I remember reading somewhere that TK uses a 50Hz transformer based inverter, so there could well be some similarity in the modus-operandi.
