hi everyone,

My latest  discovery was made using MC34063

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.

----------------------
Can anyone advise?

Well done Magpwr, i like when small changes out of the usual bring such results. I have never used MC34063, but i will keep it in mind!

I noticed this same effect of attracting each half of a split core,  in some mazilli experiments using tv yokes. For first time i noticed it in Lithuanian experiment. Indeed, this happens at low frequencies making the core to behave like an electromagnet.

This is so true! At step up transformers with many layers, is vital to start each layer from the start, so capacitance is more evenly applied and voltage difference also is more steady between neighbor wires of different layers avoiding this way arcs between layers!

Today i made my first tests in a Dally like circuit. I have to say that i am impressed of the result. Instead of pulse generator, i discharge a capacitor like in Tesla coils, through L3. L4 which is the output coil, is tuned to the low frequency, and can charge rapidly (and i mean rapidly) a 330uF capacitor at 80V. I am in the way to step it down and re-drive the input at 12V to feedback the hurt of the system which is a mazilli running at 12V/2A.

The most important in an arrangement like this is to make L3 which actually is a Tesla primary, to ring at HF. Even i had calculated it to ring by itself to the right frequency, in practice is very difficult. Unfortunately i had to go to work and i stopped my tries. I will continue at night.

Gosh!! OU is a drug like addiction!!!

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.

Because ferite core many cost. If you make big Tesla coil, you think how many cost ferite core?  And you can not use hight frenquencies (500 kiloherc an so on), because ferites best work usualy on about 35 kiloherc in 90 kiloherc for exaple, they can makes hot.

Hi MenofFather

Thanks for answering my question.. I really dont know the price of ferrite and maybe your right thats the best reason why no body use ferrite. I was thinking to make a tesla coil that doesnt need tuning and the only way i can think of to do that is making a tesla coil with ferrite core. Suppose I have a ferrite transformer, one of the secondary terminal is connected to the ground and the other is in the torus. Then I send a voltage to the primary coil and when the core reach its saturation, the voltage source is cutoff. Now the secondary will oscillate on its natural resonant frequency so no need for tuning. The frequency of oscillation depends on the inductance of the secondary coil and the capacitance of the ground and torus.

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.

Magpwr, approximately what are the dimensions of this transformer in the photo?

hi jeg,

It's estimated 4cm width and height.

I just modified the earlier post with this comment below in case you miss it.

I found out today the fastest way to charge 450volts 220uf x 4 capacitor in series using this transformer is to use (1200volts x 2 in series for each side) to form a 2400volts full bridge rectifier.Sticking with maximum 1600volts to charge 4 xcapacitor giving some buffer.
This is for my upcoming Don smith china replication project base on page 260 PJKBOOK.pdf.

The pcb design for isolated driver stage for 6 x CREE IGBT in series is nearly completed using TLP705 instead of FOD3180.Since it's able to maintain 20volts output with 20volts input compared to FOD3180 which the output is 4 volt lower at 10% duty cycle 8volts lower at 20% duty cycle at around 230khz at input.

TVS diode used to protect igbt gate is P6KE20CA (20.5volt bi suppressor base on test)

But won't be testing with cree igbt(the 2nd cheaper version at around $16USD each) for a start at lower frequency.

These are my scope shot from opto isolated IGBT driver TLP705.Noise is present only because long croc leads and using breadboard for PWM I/C:3825(produce better square waveform at 230khz) for testing stage instead of UC3525.

Currently waiting for nearly size of A4 pcb board to arrive and other missing items.
