Nice point of view d3x0r. For sure, what ever frequency is being used it has to be in a harmonic relation with the other, and wiring has to follow the wavelength relations.

ps1. after viewing again Dally circuit, as MenofFather said 1.5uF is an indication of a low frequency component. So i will start from there.

ps2. Dally's TL494 is configured as to give an output frequency between 5-500Hz

hi everyone,

My latest  discovery was made using MC34063 pin 1,6,7,8 tied to positive, 2n2 capacitor at pin 3 & 4.The output is pin 2 used as high voltage sensor to shutdown PWM controller at the right high voltage via 330ohms to base of NPN transistor 2n2222 or 2n3904 with it's collector connected to shutdown pin of PWM controller and 12volt supply positive rail via 1k resistor.It's emitter and collector connected to 1nf capacitor to reduce superimpose noise coming from MC34063 with PWM controller and also to increase high voltage output.

I was successful in using MC34063 as adjustable high voltage controller using it's pin 5 via 20Mohms resistor(2 x 10MOhms in series) connected to positive of 450volts 220uf capacitor x 3 in series and another
22kohms...100kohms from pin 5 to ground which serve as adjustable high voltage controller and capacitor negative to supply negative.

We have encountered or seen members in forum whom experimented with ferrite core where both "ferrite cores" refuse to spilt apart while in operation.
I found out that ferrite core would be extremely hard to break apart if the low frequency around 2.5khz from MC34063 in my case is superimpose onto high frequency from PWM controller via it's shutdown pin.

This is something to think about on why ferrite core(Step up transformer used to charge capacitors in series for my case via hv diodes) are hard to break apart under certain conditions.

This is completely different from core saturation at high frequency where transformer output conversion becomes inefficient.

----------------------
I have attached my special step up transformer which the primary and secondary winding is nicely isolated which improve efficiency.Not many turns is required at the secondary windings(<130 turns) to get >1000volts using less than 100mA at 12volts.
This is the most easy step up transformer i have ever done winding on,no precision coil winding alignment steps is even required.
This transformer was delivered wrongly to me when i ordered ETD3X transformer.

I don't know what this design of transformer is called although i have seen similar mini isolated transformer  in BBQ spark coil(Where each step up stage/winding is isolated from each other)
Can anyone advise?


--------------------------------------------------------------------
Finally found the seller for this transformer.It's the same seller whom sent me the wrong stuff but end up being better than expected.

Im just wondering why no body use ferrite core in their tesla coil? Ferrite core greatly improve the coupling between the primary and secondary resulting in increased effeciency. Don smith said use frequency above 20khz in their tesla coil and ferrite have operating frequency more than 20khz.

hi Neo-x,

I have actually used ferrite toriod core and nanocrystalline toroid ore (both case 18 toroid stacked and taped) and placed it in the middle of mini Tesla coil.
Using oscilloscope probe placed nearby i noticed the oscillation frequency would be lowered to around 350khz depending which core used without having to use Aluminium air duct or etc in circular formation on top of Tesla coil in order to lower frequency.

Nothing much to report-Besides decrease in oscillation frequency AND the spark length produced is also little longer.

Hi magpwr

I think the frequency is lowered because of increased inductance in the primary coil. You need to retune the primary and secondary if that is happen.

high voltage transformer (google image search) reveals a lot of transformers with segmented construction....  (stanley meyers VIC for resonant HHO also... )


if you do it all in layers from top to bottom and back, then you end up with low voltage windings near high voltage, and can arc through the insulation... if you do a band and another band etc... then each band is progressively higher voltage but within a single section is a lower overall potential then back and forth methods.


This last transformer, I don't have separators, so I wound narrow sections of bundled 30 windings and then wrapped that with electrical tape; I under estimated how much space it was going to take, so I ended up making 3 layers of these... but on the transition went from end to start with half a turn... so each should only be 1/3 total voltage difference between each layer should soak the whole thing in wax or something too; but I guess I'm gonig to suffer with just a little over 2000V trasnformer...


but then the high inductance makes the current increase so slowly; the frequency is way down ... adding some 500nF it gets down from 10Khz to 139Hz though; so a little more and I could tune it to 60hz *shrug*
