@Yucca,
well done.

Now you need the right 50 or 60 Hz transformer resonance frequency LC circuit
to pulse this via your HV circuit.

Hi Jesus,
if you switch a coil via a transistor or MOSFET or other
electronic component you have to take care about the
BackEMF voltage of the coil,
when the transistor or MOSFET is switching off the circuit.

So you need a freewheel diode or a cap in parallel with the
coil, otherwise it will kill your electronic switch.

Better use a cap in this circuit and use a transistor or MOSFET
that can stand the high ringing voltage from the BACKEMF.

A freewheel diode will just kill the BACKEMF into heat and
will not have the ringing, that might be important over here
to energize the seondary transformer coil for higher output.

Pay attention, some MOSFETS and Power Transistors
already have a build in freewheel diode, so these
would probaly be not to good to use..

But never use just a coil alone without the cap !

Regards, Stefan.
P.S: I think it is much more important first to have
a good 50 or 60 Hz resonator circuit.

Thank you @hartiberlin !

I discovered that what stopped the circuit was that the collector pin got so hot that melted the breadboard plastic and hence no connection.
Maybe 10 turns is too much for the collector.

About the cap parallel with the coil.
The coil is three legs after joining two legs at the positive.
Where would be parallel the cap. I mean which two legs I should use.

Hi All,

Up until now I have been driving my flyback using a pulse circuit driving a FET, this has been terrible, blowing FETs despite protection and sometimes blowing other ICs too.

I believe I have found the perfect single transistor drive method, It is basically a Joule Thief, using two primary coils in the flyback, this site has a great tutorial:

http://www.angelfire.com/80s/sixmhz/flyback.html

I have built this driver using a 13005 power transistor, not all transistors are suited, you need a transistor designed for inductive switching, the 13005 works great!

I also swapped the resistors for a 1k Ohm and a 100 Ohm (0.25 Watt), the suggested ones were getting too hot at 12V input.

NOTES:
In the picture below of my driver the toroid is a twin choke on one core to stop high frequencies getting back to the PSU, it is not a Joule thief or anything like that, it's just for filtering, also the blue capacitor is across the PSU input for further filtering. Before I added these components my PSU digital readout was going haywire!

The LED is just fed with 470 Ohm resistor and it just shows when the input power is on.

Anyway the bare bones circuit is 1 transistor and 2 resistors and I can only recommend it, the transistor runs as cool as a cucumber and I get good strong HV output.

Congratulations @yucca !

Are you going to post that specific schematic of your flyback circuit configuration including the toroid filter connections?

One pin of the cap at the positive and the other at the collector ( at the
third pin of the coil)

The cap should be around 500 pF at 3000 Volts voltage rating.
YOu can also try 1 to 10 nF at the same voltage rating.

Depends a bit on the coil you are using, how many turns it has..

The coil has 2-10. Meaning 2 turns for the base and 10 turns for the collector. It worked so strong that it sparked around the piece of pc board left on the flyback.

If I have to get a cap with that high voltage, that means that the project will stop for a while.
