hi NickZ,

Base on your attachment have you look into the L8 little to the right where there is a straight line drawn downwards which can be a "static collector" which assist to sustain power at around 1/4 load.

I have found a very interesting link on how to make a HV\static capacitor using aluminum foil and plastic sheet.
I'm gonna use the static approach to observe if there is any notable improvement in power output/power input.

Another known method is to use the coaxial cable as a capacitor which is charged with DC 70...90volts.I think this is also where the yoke\inverter also plays a role to step up voltage.
 
http://www.instructables.com/id/How-to-make-a-simple-High-Voltage-Capacitor-for-T/

I will release a video to demonstrate this static charge and how it effect the power output\efficiency to ou perhaps.
I think got this figured out in my virtual lab inside my head.

-----------------------------
I manage to find a interesting circuit on how to superimpose high frequency onto 50HZ\60HZ source.Please refer to attachment for knowledge purpose.
110v\220volt source can be 12v sine-wave inverter  to transformer or direct if circuit is modified to superimpose high frequency on 220volts without transformer.

Or using a 555 to opto-coupler to triac or maybe mains solid state relay to safely superimpose high frequency onto 50HZ\60HZ directly from portable sine-wave inverter.
Magpower  hi, can I just ask did you ever trap any rewards from any of these circuit ideas of superimposing HF onto AC mains ??????

I didn't test it this way but with secondary disconnected, it is clean without ringing. Do you think it will be better with 15V? Tomorow i hope i will test some more toroids, and probably i will go to less than 2uH.

Do you find a good idea at the output of 4420 to use a clamp with two diodes to limit it at the 12V level?

Good day Jeg

Do you mean 2 microHenries for the inductance of the of the Primary/Secondary windings?

If so, what frequency range are you driving it at? If I remember correctly, I used approx. 850uH @ 260Khz for the SSTC, gave very clean gate drive signal, no droop and no ringing (this has much to do with coupling capacitances & secondary side regenerative circuit).

I'm not sure what your board layout looks like, but from my experience you should get a very clean signal on the Secondary/Gate side of your GDT. 

Also not sure what size decoupling capacitor you have in series with your primary of the GDT, but if it is too small you will have problems with quality of the output on the secondary.  For a clean/Strong signal on the secondary of the GDT, I use about 500pf-1uf when dealing with nano-second duration pulses.  Pulses of longer duration require more capacitance in series with the primary of the GDT.

Also try driving the primary with a double-ended configuration. This gives a negative offset to the output and cleans up the signal over a single-ended drive.

I personally would not drive a mosfet with less than +15 to +16vdc and always float a negative offset to avoid spurious turn-on.  The configuration of the secondary side drive electronics before the MOSFET gate is important also, not sure what your using to *regenerate* the signal.

take care, peace

EDIT:  posted two very good options that are Single-ended drive configurations.  Used the second option in my Three Switch Flyback with regenerative clamping. This options floats a -4.7v at the gate.
Don't use the Tamura508 pulse XFRMR, it will over heat when used with large Duty Cycle.

Faster - yes, but it will not help with the ringing.

How much ringing is there without the GDT, anyway? ...with the TC4402 driving the gate directly (with minimal drain voltage) ?
Make a macro photo (or drawing) of the winding layout of your GDT if you want me to help you improve it.
Possibly
Hi Verpies
I never tested connecting it straight on my mosfet as I went for a gdt right from the start. But I can bypass the primary and connect a 4 Ohm resistance to see what is going on.

My previous driver behaves better as my trifiliar winding was placed as 12T forth all around the circumference and then again 12T back to the start with same winding direction. It is as you had described it again when winding the lossless clamp design. But my second driver's toroid was wounded as 15T only one layer. I will try it as 7+7T back and forth to see if there is any improvement. The layout in general is clean with short connection distances. I even use a micro-inductance for supplying tc4420.

Hi lost_bro

I did a mistake on the inductance values. I meant mH instead of uH. So my acoustics driver uses a 6mH, and the fast driver which is for use between 100-300Khz is 2mH.

By coincidence, as a layout I used the first schema of your attached files. Perhaps it is not so a coincidence as I also founded it a very nice single ended approach. See attachment. What resistance value in place of 10Kohm do you suggest for 100-300Khz operation? 10Kohm works nice at 20Khz. I intent to take it down to 5K for the fastest range. As a coupling capacitor I use a tantalum at 2uf for the acoustics range, and 1uF for the faster driver.

I think that I've got addicted by gdt's. I need to order some more Toroid's.

hi AlienGrey,

Looking back at what i posted jan 2014.I am having a good laugh because the answer to the Akula old kapanadze device related to the harmoncis was there in front of our eyes.
But i took a longer harder way to decode by looking at old Akula videos.

Please do ignore the superimpose circuit.It serve no purpose at all related to 50hz/100hz  and high frequency in kapanadze.

------------------------------------------------
I do wonder if anyone was observant enough to understand in old video Akula was using  high voltage dc from A/C 220volts inverter to power the
tesla coil(resonant at 3x the input frequency ~50khz.Input frequency is matematically related/follow tesla resonant frequency) and kapandze coil via the 3 turns from yoke.

The coil in yellow is  the tesla coil.Please refer to the attachment.The cylinder is the Antenna (Aluminum foil at the top spotted from old Akula outdoor video but can't see inner foil)
Static to current converter device.
Is static is called a ether back then.Classic English terminology?

If anyone experimented with pwm circuit using high voltage DC250volts for my case as shown in my older video.I have revealed at around 50second into video that output at 3 turns is around 192Vpp.

PWM Generator runs on 1xLi-ion battery and works with 250VDC
http://www.youtube.com/watch?v=cGRPKNhC_TE

Continue from above if you observe in Akula oldest video related to kapanadze he was using around 28turns from yoke instead of 3 turns from yoke to power the kapanadze coil using only
variable dc supply.
Using around 28turns from yoke to power kapanadze coil would give around 200Vpp as well.

Long story short-3 turns from yoke was used only provided if high voltage dc is available.28turns from yoke was used to power kapanadze if lower dc voltage is used.

Prove-This is the first Akula kapanadze video demostration before the outdoor self run video.The mini kapanadze coil is placed at the bottom in the middle of pvc for the outdoor video.Tesla coil was wound first and then the mini version of kapanadze coil wound over.

Akula0083 - Transformer in the air Video - Demonstration
http://www.youtube.com/watch?v=ccEX4H3D2IA

This the only video which reveal Akula was using 28turns yoke if  using low power supply instead of 3 turns from yoke to power the kapanadze coil.

----------------------------------------------------
Parametric oscillator is a requirement for the new device.Assemble yourself.No hints. ;D

Think about it why high voltage capacitor was used to power kapanade coil from yoke and why high voltage ceramic capacitor rated around 2.2kv was used as part of the snubber circuit for the IGBT.

"Please do not use TVS diode if we need to block high frequency from effecting the IGBT gates".It's the simple reason why Akula used dual Zener diodes for each IGBT since the zener got a poor response time compared to TVS diode.Harder to explain in one sentence. :D
But i find that ferrite beads at IGBT gates also does a good job at blocking high frequency noise.

That's all for 2016 from me.

Merry Christmas and a Happy new Year.

There is something about that circuit that doesn't make sense to me.  In the lower right there appears to be an inverter circuit that takes 12 volts DC and converts that to 220 volts AC and that is fed to a bridge rectifier that changes that to 310 volts DC.  What is confusing is then the 310 volts DC is apparently connected to the center tap of the transformer on the left of the drawing.  So what is powering the transformer?  Transformers don't work on steady DC power.  Is there something missing from the drawing?  What do the two outer legs of the transformer connect to?

I think  Grumage built this device I wonder if he will re-look at his device ?
Also the coils l5 to L9 I 'm not too sure how they are wound but won't they have to matched with a transmission line device ? is that what his spectrum analyzer is for ?

Hi Carroll.

No problem.

For any newcomers visiting here's my video.

I was creating so much RF that this video was the second attempt, it froze the above at the end, just the audio continued to work...

Cheers Graham.

Hi Grumage any idea what the value of the unmarked coil is and or what harmonic it resonates at ?

and what details have got on your advancement on the device, or any one else might have.

Dear Mr AlienGrey.

Are you referring to the schematic perchance?

The inner coil was a guesstimation...... I used 650 turns on a 50 mm plastic former in parallel with the special Aluminium plates that formed an LC circuit. The drive frequency was 9.7 KHz but the inner LC circuit resonated up in the 20.3 KHz area. I used a heavily insulated 10 turn pickup coil for the scope that was indicating nearly 10 KV P/P. I could smell Ozone regularly!

I stopped experimenting because of the expense.... those IGBT's were £13.00 each and I went through quite a few. Hoppy pointed out that my drive circuit had excessively long gate wires that were prone to false triggering, the lack of decent snubbers was another area of concern.

Kind regards, Graham. 

PS. Switch on your Skype !!   ;)

Good evening Jeg

Yes, 2uH would be a very very high frequency GDT ;D

Probably not a coincidence, I would tend to agree with you. I experimented with many different secondary side configurations also.  This design has decent response and a low parts count.  On my 3-switch-flyback, I modded the second scheme listed by placing a reverse parallel 1n4148 diode along side of the Gate resistor.  That helped speed up the *turn off* gate discharge time, but still used the 10Kohm resistor.

"What resistance value in place of 10Kohm do you suggest for 100-300Khz operation? 10Kohm works nice at 20Khz. I intent to take it down to 5K for the fastest range"

Actually I only have used this scheme and the second modded scheme for applications well below 100Khz.

I always use a Double-Ended drive topology (floating a neg. voltage) for any High-Speed, RF applications.
I seem to get faster Rise & Fall time and therefore a cleaner gate drive signal with the Double-Ended approach. I believe the results justify the extra parts count and board real estate for the Double-Ended topo.

If you add the inverted Zener diode (cathode-cathode) with the 1N4148, you can generate a negative voltage at the gate.  Only increases the parts count by one.  You will have to augment your Vcc to your driver IC, as your entire voltage range will be shifted negative by the voltage rating of your zener. So if you want to float -10 volts @ the gate, use a 10Volt Zener and increase your driver voltage by 10 volts to maintain the same Positive voltage.

I am surprised by the distortion on rising edge of your gate drive signal in your last post.  Using the first scheme, you should get a clean well formed rectangular pulse @ the gate.  Like Verpies said, the leakage inductance appears excessive and it could be the coupling between your primary & secondary windings is NOT sufficient.

Try using 30awg magnet wire,  twist or braid about 9-18 strands together to form a single multi-stranded litz-like cable.

Then using your multimeter, pair up the wire ends at both sides after after winding your GDT.  I have found using many pieces of fine, thin gauge wire which is tightly braided/twisted gives a very low leakage inductance and outperforms a single larger gauge every time, especially at RF and renders a very clean gate signal.  Of course this only works for a 1:1 drive ratio. You can configure the same braided/twisted group of wire into a 1:2 drive ratio, but you must set it up like a bifilar between two different pairs within the braid on the secondary.

Good luck.

take care, peace
lost_bro

EDIT: just looked back at your o-scope screenshots............. my bad, 650Khz!!!!!!!!!!!!!  I would definitely try a Double-Ended topology for those frequencies, and braided litz-wire (homemade of course). I would also use a pair of high power drivers with extra pin to pin decoupling and a ground plane (if possible) for the GDT primary.
