@ kings

think about that:
resistance of bulb. filement is very different in temeperature (brigthness.)  if hot (white) can be 1 Kohm
if dark (test ouf ! very low) if red ( half voltage , perhaps 500 or 700 ohm - so the power is in any way HIGHER @160V as you calculate it.


@comster.

never use  2N3055 as driver for 2N3055
take 2N3054 (if Load >12 Amps)
Take 2N3053 (If load approx 5 Amp was expected.

Hello Turbo,

I really want to know how your circuit works.

I tried to make out something by watching your latest videos.
Please would you confirm my presumptions about your driver circuit?

This is the picture I got from your circuit:
You use a basic adjustable sqaurewave generator which drives a MOS FET.
The generator and the FET are located right top on the circuit board, right?

Right at the bottom of the board we see the 3V lithium cell and the switch
for power on the generator.

The 15 big parts on the other side of the circuit board seems to be
a HT-cascade made of high voltage capacitors and diodes, but I am not
sure about that.
Here I need a little help, beacuse if this is really a HT-cascade, then the
wiring of the flat bifilar coil to the cascade seems to be strange for me.

The flat coil is wound as a bifilar coil. The two wires are connected together
in the centre of the coil, right? So it's a two layer bifilar flat coil.

The rest is 'normal' teslacoil stuff.

I made a ragged draw from your setup. Sorry for the low quality, but I am
at work at the moment and I used M$-Paint for it.
(So, I am on stress now, because I have to work instead of painting drawings
and writing messages ;-) )


The more I look at the video, the more I am unbelieving that it is a
HT-cascade. The flat coil is wired with both wires at two pins of the
"the top end" of the cascade. This is strange if it's a cascade... or
did you lay the gnd of the cascade to the top side?

I am not sure where the second wire from the flat coil is connected to.
(see drawing -???-)

Please would you explain what this 15 slant parts are doing if they are
not a cascade?

And I have a further question. In your very first video in this thread you used
a completely different circuit with 3 FETS and without any tesla coil stuff.
Why you changed your design so dramatically?

Sorry, if you already answerd such a question... It is hard for me to
understand some of the long english posts, so I skimmed most of them.

Thank you very much for all you gave away!
You will get standing waves -ups- standing ovations from me!

Hi Otto,
Perhaps you should look at a PWM chip like the TL494, TL594 or the more recent and for me, hard to get hold of TL598.
These are all 16 pin push-pull chips but can be set for push only and give you zero to 89% duty cycle and are suited for driving a MOSFET direct.
Low external component count, stable even when the duty cycle is changed, good output current and works up to 300Khz.

These are fairly cheap, 2 for 1 USD (TL494 & TL598) and just over 1 USD each for the TL598.
www.newark.com if you are in the US
or
www.farnell.com if you are in the UK.

There are 8 pin PWM chips around too, so it may be worth looking at these too, but I can comment from experimenting with the TL494 that it works well. I have used 555 timers in the past too and they OK to a point but are not really made for driving coils like the PWM chips are.
UC3843 chip is 8 pin, 200mA output,500kHz max. but I am not sure what the lower frequency limit is, this would need to be tested
(anyone already have this chip or know its lower limit?)
