Probably, instead of the 28v Zener diodes, you could add two snubbers to the drain circuits of the mosfets. See in here: http://www.ee.bgu.ac.il/~pel/links/DESIGN_OF_SNUBBERS_FOR_POWER_CIRCUITS.pdf

Hi Hoppy,

that looks like a TK/Naudin replication diagram, which as we know, did use 50Hz modulation.
Anyway, they are closely related (cousin).

Concerning the coupling between vco and nano-pulser, what is that (K)?  A switch?

Thanks BB,

intresting read; i will dive into the world of snubbers.

Yes, its a just a changeover switch.

Whilst on the subject of components, some if not all AT / ATX PSU's can be switched 115 / 230V AC input, so I'm wondering that as Dally had a 150V DC rail, which way was his PSU switched? The typical input current for a 200W PSU is 6A / 3.5A and 9A / 4.5A for a 300W PSU. Given that dally reported some PSU's he used burned-out, he was probably having trouble with the unregulated and spiking supply line, so a suitable rated DC transorb my help here.  Looking at the specified mosfets IRF 1010, these are rated at max 55V / 85A, so a large initial start-up current is available before the 150V rail voltage is pulled down by the load. However, the magic is switched on before the load is connected and the self-running loop hopefully established

Hoppy,

i wonder why the switch is there,  to switch what?


Concerning the ATX, the internal 150 DC rail, is just that, an internal 150 DC rail only to supply 150V DC to the nano-pulser.
It is not connected to the ATX ps.

This ATX PS is connected to the L4 output coil which suppose to supply about 200/250V DC after being rectified by the FWBR and the 3 Caps.
Most switched PS's will work ok, on 200V DC, and as they have good filtering on the input i doubt that those mentioned burned out PS are damaged by spikes, more probably because of too high (DC) voltage.
So a stabilizer (200V zener or so) might be good to implement.

I estimate that the whole internal Dally device is not drawing more then 1Amp at 12V.
The excess energy lightning the 220V 30W bulb suppose to come from the L4 coil "in combination with"/via the ground connection.

Anyway, this i my take on it.
