Barbosa and Leal Devices - Info and Replication Details
It was several posts back where he says he is working in the kilohertz range, so it would be easy to overlook that part.
Yeah, forgot that. But he does say he ordered twelve 10 megohm resistors for the divider network. With regular electricity, that will limit the load to just several microamps. But BM claims this type of electricity likes resistors, and Clarence says he knows what he's doing, so I'll shut up and stand by.
I did not know the frequency and that was why I said "If 50-60Hz". And if he doesn't want or can't find a high frequency transformer, it would not be too difficult to wind an air core transformer, would it. But let him use the divider network. Maybe they'll get cold instead of hot and there will be no wasted power.

Transformers are used every day in radio transmitters all over the earth. They can easily be used up to gigahertz frequencies if designed properly. But a transformer for 60 hertz will quickly overheat at 400 hertz if loaded. The transformer has to be designed for the frequency. A bunch of resistors as a voltage divider is wasting most of the power in heating the resistors. A transformer allows you to use most of the power instead of wasting it.
Thanks Sis,

I have decided to use a more direct method to use the first TBC as a powered voltage source the keep the battery from its continued drawdown.
..........................................
I have already briefly used the assembled components and they work quite well.
I am now waiting for several more 10 Mohm resisters to drop the resultant DC voltage down a tad more. thought I needed only 8 of them but now I know it will take twelve of them to get the job done.
When finished and run I will give results as usual.
when I was briefly running this FWRB the total input was 120v @ .51 amp.
I said to myself , if that carries true all the way through into the battery circuit that will be amazing! that was driving the power supply , the ZVS
unit , the TPC , the TBC , the FWBR , the voltage divider , the smoothing capacitor --- awesome HUH1
Also note on the attached voltage divider circuit that the last resister seems unused ! however I believe it serves as a bleeder resister to keep discharging the smoothing capacitor, otherwise there would not be anything else to accomplish that? and also at the end of any run the capacitor would be left ready to kill you. notice the earth ground attached to the capacitor also!
during ALL this bouncing back and forth about a transformer it evidences a gigantic miscomprehension .
first of all, ALL of this information bandied about I have KNOWN for MANY -
MANY - MANY years! you are NOT teaching ME anything! Get a Grip!
the miscomprehension is the fact of having IGNORED from the start that the method I chose was due to overcome HIGH FREQUENCY KILOHERTZ!!!!!!
your supposed cure would FRY a transformer right off the bat!
it is KNOWN that resistors MAY (NOT surely) incur HEAT with usage.
SO WHAT! its called LIFE! GROW UP!

Well it looks like the fun is just beginning and the conventional thinkers
just can't seem to see some basic things. A simple regulator circuit in
conventional electronics is only good from 30v max input then only
leaving meager amounts of power at reduced voltages.
As you know other higher voltage regulators (With all of the complications)
are available if producing the most refined design right from the start
was the goal. We need to stick with the KISS formulas so we don't
lose all of our followers.
The goal of your project has been very clear to me from the start and
your practical side is so nice to get a hold of when building starts. Like
your diode cluster or other ideas that leave "STATE OF THE ART"?? designs
in the dust due to durability issues. Give me a basic design that steers
me clear of all of the endless digital toys and I feel better already.
You build things by industrial standards that are made more long lasting.
Dropping 170vdc to power a battery charger is unheard of and no one
can just walk up and buy one at the corner store, besides this kind of
energy loves resistors and might get cold instead. It's hard to
say what is going on there.
One thing i will tell you I found out, was that all circuits I ever saw
engineers design had to throw the diagram away after they ran tests
to finally alter it enough to get her going.
Looks like you are putting the petal to the metal here lately. I can't wait
to hear your shout of exclaim once again as the fruit of years of research
and testing are paying off.
Never mind all of the buzzing sounds of conventional wisdom.
You guys need to look here
Attention Dave and Marc B., Clarence wants you to see what he found
out about the divider with earth ground. This is not theory.
I don't think that will work too well on DC when there is a load.

While I agree with your post 110%, I am interested in the specs you have in mind for the transformer.
Hi Randy,
I don't know enough about his system to "spec out" components. But if it is 50-60Hz with 120V and .5A, then a 10:1 stepdown at 100VA or higher should be good for starters. I'd look for something used, maybe from an old battery charger. For that matter, why not try the complete battery charger?
Regards,
bi
BTW: The transformer will isolate the 12V side, if that is of any benefit.

Reason: added BTW
When you rectify AC, the DC voltage value will be the peak AC value at no load or if well filtered (capacitor). The given AC or the value read with an AC voltmeter is the RMS voltage value. To get the peak you need to multiply by 1.414. When you load the DC circuit, the voltage will drop depending on the load and on the filter.
Also, using a voltage divider for a power circuit results in much waste. In your case, about 90% wasted in heat in the resistors. It would be much to your advantage to use a transformer prior to the FWRB.

It seems that any FWRB circuit for some reason RAISES the input voltage to a greater value like a Voltage Multiplier wouldIn this particular case the
122 vac is raised to 170 volts.

This is an amazing post Clarence others are seeing this and this
subject of earth grounding is becoming more understood. Thanks so
much for your willingness to open your hand to the next man.
You are right the ground does play an important part in many Tesla
based devices and solves the freq/filter problem fast.
I have decided to use a more direct method to use the first TBC as a powered voltage source the keep the battery from its continued drawdown.
that method is simply to rectify the 122 vac from the TBC - then pass it through a PROPER voltage divider circuit to achieve a safe voltage level for the battery itself ( 14 vdc to 15 vdc - no more ) , then pass that through a DC smoothing capacitor and then straight to the battery circuit itself.
I said - why not? I already had available from prior art 4 each HUGE 4 amp
15KV power diodes. Vbid put me on to those years back.
so that is what I have been working towards and almost completed!
individual component photos attached!

Should have thought about all this with years of past history in mind.!

122 vac is raised to 170 volts. yes, you read it right! that's why I'm waiting for a couple more resistors from Mouser.
as a side note, this FWBR setup I have now is the same type Marc B and turion (dave) should be using.
The part # is 2CLG15KV/4A . Both Amazon and E-bay have the available
at around 24.99 each. make sure it's the large screw connect on each end!
the resistors are Mouser # MOX92021000FVE 10 Mohm - about 14 plus change .
When finished and run I will give results as usual.

Hi Clarence, my suggestion is to rectified the output and connect the DC output
to a grid tied invertor and that should cost you about 300$.
Hello seychelles,
I saw your post weeks back and made note that your information was valid
at that time.
I never intended to tye anything to an invertor since I already had an excellent one and that was the one that I have used with my CAPTOR unit from the get-go.
At the present time I was pissed at not being able to shake the high frequency made by the ZVS driver when it subsequently powered the TBC coils I have been using to produce an alternate voltage supply for the Captor set up to work with.
I first Intended to dump the voltage to ground and then retrieve it back through the earth ground also. all for the purpose to be able to supply power
to the battery charger to keep the battery from having a slow but continued
drawdown.
then I thought why to hell should I go to all that trouble to power a charger
when I can rectify all that voltage (blow the frequency to smithereens as ripples) and reduce the voltage to a safe Battery limit (around 14 v to 15v -
no more) and simply apply that DC voltage directly to the battery circuit it self- end of story.
that is what I am doing at present as you will see in the following post I make.
this made me mindful again of your post and it's valid nature. I do want to acknowledge your gracious thoughts and efforts in that direction. that's what valuable members do! Thanks again Sir and many kudos to You!
