Hello All

Just wanted to note that in this video:    https://www.youtube.com/watch?v=RUEBzjiGLPs

The diameter of the secondary of the SSTC is 30awg, but the secondary is *apparently* pulling 2.7 amperes current through the earth/ground wire, (20-30 meters of 14awg).

Apparently the gauge of wire used to wind the secondary does not *directly* effect the  earth/ground current.

Forgot to mention that the PLL is locking in at about 260kHz.............which is just at the limit of current saturation/skin effect for 30awg wire.

take care, peace

hi lost_bro,

I am impressed upon seeing your youtube videos for the first time.

At least most of us would believe now there is indeed burst of current going to earth from the transmitter end without worrying about receiver coil for now.

Let's assume you get 2.7Amps from 180volts VDC but with huge tesla coil.But if this tesla coil is shrunk to the one used in Akula device.
Then the input DC voltage would have be around 5 times higher around 1000volts since there is lesser turns for the tesla coil in the Mhz range.To ensure there is high current transfer to Earth.

Last night i bumped into some random articles on "nanosecond pulse from tesla coil" which i found out the origin of the experiment somewhat originated from Russian Serbian research around 3 decades ago which were using special spark gaps which yield impressive 1khz repetition rate to generate high voltage nanosecond pulse.

Logically we don't expect nanosecond burst rate to be the Mhz range for tesla coil which means it would be pulsing in khz range which may tally with pwm generator 12khz to 37khz.


We know that Tariel was using spark gap to discharge capacitor bank in order to create high voltage pulse at below <100hz rate which we can easily hear those repetition burst in those old videos.

I am aware that PIO capacitors 2 in series can be charged to nearly 1000volts using 4xfast diodes full-bridge rectifier (1200volts each) from the output of kapanadze coil.Less than 10watt of power is needed to charge PIO capacitors which a 9volts battery did the job just for show.

Base on my observation in one of the vasmus device close up video i spotted 1kohms resistor around 2watt rated which was connected from bank of capacitors."No other useful information can be detected"
The purpose of the resistor is to merely limit the flow of current to the nanosecond generator circuit but not the voltage if it's charged to nearly 1000volts. :)
--------------------------------------------------------------------------
I have conducted 4 different experiments on Saturday alone after doing some pre planning in my head beforehand.

My pll base circuit and nanosecond generator circuit was  derived from this circuit PLL_sinhro_Tesla_v4 circuit.
But capacitor and resistor for 4046 need to be selected correctly so that it is able to lock from 12.8khz to 36.4khz.
Once that is done R8 pot still need to adjusted in order to achieve maximum power output to bulb with 0.1uf or 0.1uf x 2 capacitor connected in parallel with bulb."Experiment was conducted previously
without frequency divider 4017 in place yet which i will explain below"

I have decided to use IR2184 which produce around 48% duty at the dual output this will replace my 74HC132 dual channel pwm output circuit.

But unknown to the creator of the excellent circuit by ALLEGGA.
He needs to divide the frequency by 2 using 4017 I/C (Akula_30-06-2014-Edited) which clk in is to be connected to pll pin 4 and pin 3 of 4017 to R8 which was connected to pin 4 of pll.
This will allow 4046 IC to produce 2 times the L/C frequency.If for example i use 0.47uf x 2 capacitor i would only get 14.4khz L/C resonance which pll locks in.But after x 2 frequency multiplication.
The output at 4046 would be 14.4khz x 2 =28.8khz.

-----------------------------

It's best to just focus on the current transmission to earth for now.

  The Akula/Ruslan device is lighting the 220v AC bulbs with rectified DC, not AC. Why are they doing this?
 There must be a good reason.  I have not tried that yet, but I will. Especially once I can find some big 220v bulbs.  NO luck, so far...

  Hoppy had once mentioned that using the 220v AC bulbs would cause the circuit to only draw 1/2 of the amount of current from the source battery, (or from it's own looped output source), compared to using 110v bulbs. Can someone confirm this for me, please. 
  My device runs hotter and hotter, the more I tune it to run at it's best output.  I can't touch the fets after one minute run time, (with fans and heatsinks) when lighting 3 100 watt AC bulbs fairly bright.
  For me, more tuning caps are needed to obtain best output. I'm using 3 tuning caps on the 3 turns coil, and a single 0.1uf cap in parallel with the bulbs, but now have added two more caps at the bulbs for increased output. AS these caps are the only form of tuning that I can do. The magnetite magnets are also helping to adjust the running frequencies. 
   My kacher is still running at low output levels, so I'd like to see about how to run the Kacher off of either the 3 turns coil, or the 168 turns coils output, as it's input source.  Any ideas???

Good to hear that you enjoyed the videos.........

Want to take advantage of the moment and make a couple of comments on the schematic that you posted:
As we know it uses Pin#14 so it is TypeII PLL, which is different from TypeI PLL on Pin#2 in that (@ resonance) *EDIT should read* (through VCO range), both the signal and comparator input are in Phase = Zero shift.  Of course the draw back to Type II is that it is very much more sensitive to EMI and sloppy board layout than Type I.

I used TypeII PLL in my SSTC design also... All the other TC designs I have seen on the web use Type I exclusively for that very reason (EMI problems).  The type I really requires much more circuitry to implement because the phase shift is variable 180 degrees through the VCO range. (90 degrees @ center VCO). 

Type I will also lock onto *harmonics* or overtones of the principle frequency, Type II will NOT lock on *harmonics*.

I took the liberty to comment a couple of items on the schematic, please see attached *commented* schematic.

Take care, peace

OK, basically Power consumption is still the *same*

E x I=P:

where E=volts
          I=amps
          P=power; watts

then:   220v x 1amp = 220watts

and;    110v x 2amp = 220watts

so;      220watt/220v = 1amp consumed

and;    220watt/110v = 2amp consumed

We can see that for the *same* amount of power or WATTS, doubling the voltage will cut the amps consumption by 1/2.

take care, peace

Isn't that obvious ? If you have very high frequency the best l you can do is to rectify using diodes and store in capacitor.

   So, if I raise the input voltage from 12v to 24v, will the current draw be reduced by 1/2.  Or not? 
   I'm trying to find a solution to the fet overheating issue, still.  So, if by raising the voltage will not help the overheating, let me know. 
    The total power drawn may be the same, but the overheating may or may not be reduced.

 
   Forest:  Obvious, no.  As I don't rectify my grenade's output to run the AC 120v bulbs.
   I rectify the device's output only for the feed-back loop back to the input side.  Which by the way is now actually helping to raise the bulb's lumin levels, instead of dropping the output when I connect this feed back loop up, like before.
  So, I can say that the (rectified DC) feed back path is working now, and the higher the feed back loop's voltage/current, back to the input side, the brighter the bulbs become, while using the same fixed power input source. 
Not self running yet, but, I'm working on it.  Still a long road ahead...

will the current draw be reduced by 1/2.  Or not?    Yes, for the *same* size load............Total power consumption remains constant unless you have achieved O.U.

fet overheating issue  There are many causes related to MOSFET overheating issues:

Overstaying it's welcome at the *Miller Plateau* ie;  slow Tr on gate signal.........  increase decoupling capacitance on driver, use a more powerful driver. Speed-up/clean-up  Tr (rise time) on gate signal.

Not reaching the *full-on* voltage level necessary, ie; from spec. sheet.

Not turning Off completely; Check with scope

Voltage going *too far* below ground while switching off; check with scope.

Spurious oscillations on GATE due to feed back circuit; Check with scope.

To low of an inductance on primary coil/ to fast of a slew rate.

Too High a Frequency; check specs...... spec RF FETs available.......

Vds overvoltage, ie; usually burns up fast............

Over current conditions, ie; usually burns the FET.

Faulty Source to ground connection, not common.

Insufficient heat sinking.............

This list in not comprehensive,,,,,,,,,,,,,, just wanted to throw out some ideas for ya....

hi lost_bro,

The circuit at pin1 of 4046 is not required it is just visual indicator.I merely connected green led with resistor to ground.

However the inverter after LM393 or TLC272 output is required.

The current sensor i am using a blue toroid mounted on the thick wire from 3 turns from toroid/yoke after 0.47ufx2 WIMA capacitor.
The 10ohms resistor and 2 x 1n5818 diodes connected as bi-directional is connected in parallel from output of blue toroid using 20 turns.

The clock capacitor for 4046 needs to changed to 1nf and resistor at pin 11 and pin 12 needs to be changed to a 100k  pot or with suitable resistors.

---------------------------
My experiment with 4017 used as frequency divider was a failure with the multilayer coil it was just stuck at 36.4khz.

But final testing merely using breadboard late last night by changing clk capacitor from 1nf to 471pf for the pll solve the problem.

I would be available on Thursday onwards to commence experiment.


--------------------------------------------
Side track which is indirectly related to my project-

I have attached a image of the world smallest modified sine-wave 220volts 150watt inverter with 300watt surge capability.

I wonder how they managed to fit a 50hz transformer in there and tested to be electrically isolated from the 12volts supply and comes with 4 types of circuitry protection.

   Yet, the guys with ALL the proper test gear have not shown a higher bulb brightness (lumin) levels, nor have no fet overheating when drawing over 500 watts to 1000 watts from their device. 
   I've checked most of the things that you've mentioned already, and I've also exchanged most of the components in the circuit several times, but I'm still looking for a solution, if there is one, other than making a new push-pull driver.
The fets that I use, IRFP260N should handle 50A, and 200v.

Good evening NickZ

OK, the first thing I would do the scope-out the Gate-Source signal on both FETs.

Then:  scope-out the Drain-Source on each FET.

This information will give you 99% of the picture as far as the MOSFETs are concerned..........

You will find your answers there.

That much being said, from what I have seen it is normal for a Mazzilli circuit to heat up the FETs a bit.  Check out this on ebay:

    Bro:
   That's the kind of circuit that I'm looking for, both for the Kacher, as well as for the push-pull oscillator. Hopefully with adjustable frequency, etz...
   They don't ship to my country, but here is one that does, and is only $15, free shipping to my door.
   Can't beat those prices, just a matter of obtaining the right driver boards.
   I'm about to order a USB scope in the next day or two. Then wait for a month for it to get to me here, at least I hope that it gets here.

    "Not reaching the *full-on* voltage level necessary"

   May be one of my main problems now, as the voltage does go down quickly once I kick on the device, which can also cause the fets to fry. I'll look into it.
   Thanks.

You are already using that same circuit, or a close variant of it. It even uses the same mosfets. You can build it yourself for even less than the 15 dollars, and you won't have to wait for delivery.  Finding the appropriate capacitors will be the hardest part. The frequency is set by the tank circuit's L and C values -- that is, the C value of the big black capacitors on the board, and the L value of the winding you put on the yoke or flyback core. The circuit is "autoresonating" in the sense that it automatically operates at the resonant frequency of the tank circuit, which can be calculated easily:
http://www.1728.org/resfreq.htm

The Ebay circuit's capacitors are selected to provide a resonant frequency of 20-30 kHz when used with the typical 8-10 turn center-tapped primary that people will wind onto the exposed part of the core of a TV-CRT flyback transformer. This frequency will generally provide the highest voltage output from the flyback transformer.

The Ebay circuit will work better because it is designed with proper layout: short leads, symmetrical output section, proper heatsinking, etc: things I have recommended to you long ago. It is the same circuit that powers the primary side of my hybrid SS-SG TinselKoil VII:

The mosfets do not run hot in this application. Why not? Think about it.

The same circuit can be used for wireless power transmission, as I have demonstrated many times. The receivers of my system will indeed light up bulbs more brightly than they light up when powered by the straight DC supply to the transmitter, and the mosfets in the transmitter do not run excessively hot.

Your mosfets will handle the power levels you cite _only_ when in circuits that are properly laid out, properly supplied and switched, and properly heat-sinked with fan cooling. Lots of stray wiring all over the place will cause inductive and capacitive effects that will result in bad switching and wasted power that will only heat up the mosfets without doing anything useful.

As far as the USB scope goes... save your money and buy a real oscilloscope. You do yourself a disservice if your first scope is a cheap low-bandwidth USB digital scope. You may be able to find a used Rigol DS1052 in the 200 dollar range, but I recommend a good analog scope as the first scope, because you will learn a lot more by using the analog scope, and you can get a far superior product for the same money as you'd spend for a low-end DSO.

The image below shows the _same circuit_ built up for my TKVII. The capacitors give a total of about 1.5 uF at 500 V, and instead of a toroidal choke I used two cylindrical chokes (black ones). I only had one 3-Watt metal film 100R Base resistor so I used a carbon one for the other side; in the Ebay circuit you can see the big base resistors behind the heatsinks.

  The Akula/Ruslan device is lighting the 220v AC bulbs with rectified DC, not AC. Why are they doing this?
 There must be a good reason.  I have not tried that yet, but I will. Especially once I can find some big 220v bulbs.  NO luck, so far...
  Hoppy had once mentioned that using the 220v AC bulbs would cause the circuit to only draw 1/2 of the amount of current from the source battery, (or from it's own looped output source), compared to using 110v bulbs. Can someone confirm this for me, please. 

Hi Nick. Not sure about the pulsating DC (i.e. rectification using diodes or a diode bridge) being
important or not at the output. Ruslan has also shown using a filter capacitor as well in some circuits
to convert to pure DC. I don't really trust what Ruslan has shown however as being something to
base your circuits on. Ruslan was constantly showing different setups, and I personally have serious doubts
that anything Ruslan has said or shown is at all reliable.

When you use a 240V/220V bulb, it doesn't necessarily mean that you will reduce current draw at
the input, but a 240V/220V bulb will have a higher filament resistance than a 120V bulb for a given wattage rating.
How much load the driver circuit sees depends on impedance matching. Maximum power is transferred to the load
when the output impedance of the output transformer winding is equal to the impedance of the whole load that is connected.
Likewise, maximum power transfer occurs when the output impedance of the driver circuitry (ZVS driver or PWM driver)
equals the input impedance seen at the input of the transformer windings. The more light bulbs you are lighting with
your driver circuit, the hotter the driver FETs will get. If you are driving quite a high power load with your driver circuit,
your driver FETs are going to get very hot. This is normal and expected. The difference with what Akula and Ruslan are supposedly
doing, is they are supposed to be delivering a lot more power to the load than the driver circuit is supplying to the transformer windings,
thus they can (supposedly) light many hundreds of Watts of bulbs without massively overheating their driver FETs. If the driver circuitry
is supplying all the power to such a large load, the driver FETs would overheat very quickly.


So, if I raise the input voltage from 12v to 24v, will the current draw be reduced by 1/2.  Or not? 

No, it doesn't work that way at all. It is all about the impedance of the load, as compared to the
output impedance of the transformer windings which you are connecting the load to. The load the
driver circuitry sees depends on the impedance transformation ratio of the transformer windings.
Again, this is how it works for normal, non-overunity circuits. If you are getting extra power from
somewhere else other than what the driver circuitry is providing, then you can theoretically drive a larger
load without over-loading/over-heating the driver circuitry.


The fets that I use, IRFP260N should handle 50A, and 200v.

Not at the same time. :) Those ratings are max ratings of current and voltage individually,
which doesn't mean you can reach the max of both at the same time. The max power dissipation
for the IRFP260 is 280 Watts. It is not 46A x 200V = 9200 Watts !!!

Nick, what it boils down to is that with the Akula type circuits, or any over unity type circuit, you
are not designing and tuning to light as many light bulbs with the driver circuitry as you can.
The goal is to pull in extra energy from somewhere else and use that to power the load as
much as you can, while minimizing the amount of power that the driver circuitry has to provide.
This is a major difference in approach... assuming this really can actually be achieved. ;)

All the best...

  Ok, I get that. Just like SR showed in his video,  he disconnects his device from the power supply, when the draw on it had already dropped down to 0 volts , and is no longer providing any input power.

   TinselKoala:  Thanks for your thoughts.
   I believe that the modified Mazilli crt that I am currently working with has all the essential features that you've mentioned.
 Like short thick wire connections well soldered, with no cold solder joints, UF serie diodes, 18v 5watt zeners, three current chokes, etz... but it can't handle 24 to 30 volts without overheating. The commercial board posted previously can....  Maybe.
  But the voltage drops too quickly at my circuit, when the 12v car battery (which can still start a car) is used.  Even when the battery is also connected along with a 10 amp car battery charger, at the same time. However the Mazilli crt can still light several 100 watt bulbs with useable brightness.
   I think that using 24v feed-back loop, is what may be needed for my circuit to shine as it should.
   My feed-back loop's output, back to the input side, is dependent on the power levels from the 168 turns grenade coil. Which are now about 12v, and will also now add brightness to the bulbs when it's connected up as mentioned.
So, I'm working on this aspect still, to minimize the input draw on the battery.
   I take the output from the 168 turns coil at both sides of the inline diode, then that goes to the rectifier diodes at the flyback core, and to a filter cap, and back to the input side.

   I don't know if using 220v bulbs will make any difference, or not. Or even the rectification of the output power to DC.  But, I do know that if the bulbs aren't getting the required voltage, the fets can burn out quickly, as well as the driver circuit that's in the the CFL type bulbs. Which in my case, any ungutted CFL bulbs only lasts about 1 minute, and will go up in smoke, when connected to my Mazilli.   But, it looks great, until then... 

  Here's a pic of my current Mazilli crt.

Hi Nick. Nice job on your Mazilli driver circuit.
I don't know how much wattage of bulbs you are lighting in total,
but if it is up around 200 Watts or more of actual power being consumed by the bulbs,
your Mazilli driver is going to run very hot, even if the Mazilli driver is running optimally,
and even if you have really good heat sinking and fans. You may just be driving too much of a load.
All the best...
