Chinese Oscillator and MOS FET Driver, Hardware experiment
« on: November 13, 2020, 10:37:08 PM »
Getting back to Chinese oscillator FET Driver circuit.
I striped down a XT power supply and re wound one of the smaller miniature long E core
'soft' ferrox former and re tested and it produces a perfect sine wave @62.5khz

This is the Device in thread tittle above !
Or is that something else ?

Chet it is the same thing. Chet we need some feed back from Stefan and a thread creating for me to copy
the series of instruction picks into with some sort of disclosure statement, it might be this the problem.

pinching bits of it is one thing we can do but the sauce now expect folk to pay them for it.

In that case Stefan might have another way of solving the problem

Not getting any reply from Stefan either


Honestly been hard  to reach him last year or more
Even worse since Covid


I will try to ring him

yes what ever you want to play it as!

there was another video where he goes out on location and uses it to cook his prawns and noodles
wow! great if it works like he shows.
wonder if any one else has any more of his vids from when any one could view FREE ?

Chet 'the cores he doesn't give any info on them the bar cores are the softer type not the ceramic type
the E cores looks like the ones out of old XP power supply.

The grenade style gr coil I think i would try a pile of rings end to end about 26mm dia the wire he used was Teflon coated
stuff out side dia is about 1,5 mm for the blue wire and the white is about 2mm outside dia to fit in the spaces.

I would have thought some bright spark would have got it going by now

Hasn't any one else got or down load's any of the old vids ?

Note the above scope shot is just the 13001 oscillator driver stage I was thinking it was much like the dally Ruslan circuit
L havent made one of them mu self the lock down came and that was that! but it has no high voltage katcher wound coil !

Thank you for some info


I am traveling / working ATM ...thru beautiful Covid capital
....NYC ( not a happy place ATM)


Will ask a few more questions when I get home
Tonight/tomorrow .


This topic has most info... a few key points need addressing


IMO


Respectfully

Guys, does anyone know how those machines work? It says 230V/50Hz but i feed it with alternating dc at 110KHz and seems that it works normally. What is the catch here? Are we talking about dc motors with a bridge at their input? ::)

In addition, i would like your help on the following.
We see at the china-kapa device that the 28T output of the zvs ferrite transformer, is in series with a cap and an output transformer. The input zvs inductors are of 5 turns each. So 24V/5T=4,8Volts per turn. So 28T X 4,8V equals 134V peak. My oscilloscope here shows almost 200V peak. Why is that? Is it due to accumulation of voltage cycle per cycle? And if this is true then do you think it is possible to raise voltage even more across the 28T coil without adding more turns to it? What the maximum voltage at this point depends of?

Thanks :)

Do you think you might be missing some thing ?  I think the fets are feeding a very loose coupled magnetic coupling across the ferrite core and also the cap isn't any old value it has to be tuned to match the two inductance's do that and see how far you can get. Lx = Cx the play ground swing perhaps.

Also when the guy was winding the coils I also noticed both sides of the wingdings were not equal or was it an illusion.

 One other thing the jig saw is inductive shouldn't it be a restive load ?

Hi AG
I don't understand what you mean about loose coupling. It doesn't look loose to me at all. Of course when it is in resonance, then Lx=Cx which gives rise to current. Shouldn't voltage have to follow the turns ratio thing?

About the Chineese's number of turns, there is only one turn difference between left and right coils. 50T and 49T. Not a big difference. The middle coils are of 48T each.

One other thing the jig saw is inductive shouldn't it be a restive load ?

Why to use only resistive loads and not inductive ones? It works with both kinds. But behaves better by using inductive loads. Meaning that COP is higher with inductive loads in this inverter.

Packing the PVC core with magnetite composit would be much simpler then shaping that rectangular job right?

There is really not much to this build; The coils are household wire! What kind of advantage would there be in building a ferrite core with blocks? Permeability can be controlled with particulate ratio.
