I found that the magnet dont cause mutch effect on this new transformer.. i believe that is because the primary winding is much wider than the other i tested before.. So the exact effect of the other transformer was having the primary about 3 cm wide and the magnet being 1cm  between north and pole...




I got the exact pulse wave form meyer showed... thru the water thought. Using the big green inductor connected the way i showed in that drawing... vic by sebosfato

now i just need to get into resonace...

I tried to attack on the 110 volts line but my dimmer burned in 5 seconds got also my irfp250 burned too... i will go buy a fuse and will connect straight to the line again=)... i will buy some of them...
And i need to go buy some more diodes and mosfets...

Is because i don't have a variac so im connecting straight to the line..

Alright  Fabio. Closer then ever.
Maybe a scopeshot?????

I went to the store to buy the diodes and the mosfet and i ended up buying some fuses and an igbt caled irgp30b120kd-e 1200v 30 amps


I was afraid that the irfp250 burned because a spike than i will find how to make a snubber well avoid burning this igbt witch was a bit expensive. .


I will solder everything up and i show you the scope


You will see the spikes... than


i need to add the second diode to create the step charging effect...


than is a matter of inputing voltage up to here the hydrogen will blow out of the bottle...


My friend engineer is going to make some tubes for me i think he will make three tubes sets with 1mm gap...


This way i can vary the capacitance...


The unipolar pulses are really interesting as seems full wave bridge rectified but the pulse is being generated by the collapse of the field in the coil.. as together with the spike...


shortly more to come


wish me luck

Seems like the sky is helping me. A lot of rain just arrived, i'm collecting the water...

I've got many problems and i'm not able to get the same wave forms anymore


my primary shorted


the irgp don't act like the 250


i'm going to buy some bidistiled water adn a irfp360 transistor

I just came back with 20 liters of bi distilled water and a certain resin that i can use for make more 200 liters of it...


The conduction is 3 micro siemens


Now i just need to rewound my primAry and substitute some diodes here


i think they got burned with the unipolar pulses they are 60 amps 600v ultra fast diodes and the one in the coil actually got really really hot

using 12v i made the ac voltage raise up to 250v


having about 5 v dc


I think now would be worth some of that dankie wire ...


I'm going to buy some wire tomorow


I don't have more..  Hum thinking a litle better
 


yes i have

Add a small computerfan on the hole VIC, Seb. If you are lack of those, then i can send you some....
