Magpwr,

thanks for your comments, but could you elaborate somewhat on  "The bi-directional TVS diode 54Volts is not applicable for mosfet rated 200volts"?

Obviously a 54V TVS would not work when switching the max. 200V, but as we only should switch 48V with this 200V rated MOSFET, is it still "not applicable"?

The both TVS stay cool so i guess they are happy.

regards Itsu

hi itsu,

What i was trying to say the 54volts is underrated for your 200volts mosfet.
Why not create a one PWM circuit that works all the way to mains voltage around 300volts.

The best way to know just disconnect the output to kapanadze winding and note the bare Amps reading should be below 1Amp better still below 0.3Amps with yoke or toroid in itself.

I can't comment on your snubber because i am just sticking with Akula snubber which work at high voltage.Akula snubber circuit tallied by visual snapshot uploaded by someone in the past.

I just hope you don't get stuck at PWM.
-----------------------------------------------
I am currently working on Oleg nanosecond generator(Position control) which is combined with a  75hc132 1Mhz+ duty cycle control  via a sk diode.Something similar interrupter circuit of Sergey.

Doing last few test/adjustment at 23volts before going high voltage around 150volts to 280volts using 1.2kv mosfet once more for my high 'Q' Tesla transponder coil with Water pipe as Earth.

Variable capacitor 20pf to 1nf 1kv rated is used to find out the what  capacitor value to use to derive a suitable waveform display.

Magpwr,

please forget about the efficiency for now, the bulb was just an indicator for resonance.

It does not matter what MOSFET/IGBT i use, they are not the cause of the amp draw, they are staying cool (19°C), but instead the
inductor coil / Wima caps series LC in resonance is causing the amp draw as there is about 750V @ 50 amps sloshing around there.

I could use 60V MOSFETs here as we only are on 24V (causing 48V to be switched) but the IRFP260's is what i had installed already.
With 60V MOSFETs the 54V TVS would be "applicable" then?

As i want to stay as close to the original plans as possible, i would not want to use a "PWM circuit that works all the way to mains voltage around 300volts"
Not sure what you mean by "kapanadze winding".


Thanks Itsu

hi itsu,

I meant do test yoke core in itself with nothing connect at it's output.

You should be getting <1Amps draw.If not you got to look for other alternative core or toroid or redesign circuit.

Time is running out i got to continue experiment then exercise then research to wrap up my day in the end.

Ok,   it draws 500mA when nothing connected to either the 3 turn or 28 turn secondaries.

Happy experimenting with the Sergey nanopulser.
