Nice setup, keep posting for me a new video when you get time. I hear the singing up and down as the oscillator works to charge the capacitors.

A#1 Job

I will post more video, this is better than text.

BroMikeys Updated Oscillator

Here is my latest working upgrade for the 14awg 7 pound Bedini
wound coil for the solid state SG or SSSG.

Force oscillator without the magnet triggering My favorite.

With these updates you can easily charge a 90vdc dump or
run straight to the battery with double the efficiency. The
new fast recovery diodes save enormous amounts of
power from heat loss. Earth shattering difference.

The bigger high powered set of transistors make use of the
large AWG wire winding. Input tested from 12vdc to 40vdc
@24 amp Max.

[BroMikey]

Okay been waiting for parts and while
I have been doing that I have been using and
blowing single devices (MJL4281A) and diodes
to find their limits.

One transistor can only stand so much and to
find a place of usage and durability I have been
building a single channel Osc and Mini -Capacitor
discharge bank.

The capacitors are arranged two 63vdc in series
giving me a 10,000uf @126vdc rating that will be
filled to 60vdc.

This bank is a 50,000uF@126vdc and wow what
a crack it gives at 60volts melting metal.

A very compact design. These are the only caps I
see anywhere that fit the bill. Check it out when
you buy caps in bulk they are a good price for
many up to 50vdc and then it jumps to 220vdc.

I thought about using the 50vdc caps but for
another few bucks the 63vdc caps can be had
giving me a higher ceiling without much extra
space required to house them.

The transformer build you see is a core split into
sections from a microwave oven transformer.

The pre-wound coils come from the ice auger
from a Side by Side refrigerator freezer where
the ice machine uses a gear reduced motor
to crush ice. The 22awg wire is rated at 3 amps.

These coils and spools will slip right over a MOT
core perfectly. This way i can wind my own
transformer to get 12vdc to power the 555 timer
or 12vdc cooling fans and at the same time using
24vdc and 36vdc for a wide range of battery charging
applications. Transformers with a perfect amp
handling capacity with multi taps for your exact
voltages may be harder to find than you think.

This approach solves the practical issues.
I will give you the turn counts to get some
of you in the playing field. Typically these
particular 22awg spools are 140 foot running at
120vac so figure on measuring voltage every 25
turns or less to get the desired voltage.

For charging a scooter battery pack I use the
36vdc tap to feed the OSC that raises the voltage
to 45-65vdc that in-turn fills the capacitors for
discharging at a fast enough rate to accomplish
the task in a reasonable amount of time before the
sun goes down.



The air coil I just wound in 20 minutes was the
most pleasant wind I have ever made using the
big winding machine. Throw on a few tie wraps
and bang, you have your new coil to run tests on.

The first small one was 26 awg and to small for my needs.

My goal is to have a idiot proof design that will last
forever. This will require that I use the trigger wire
to stop the Osc from going above 60-70vdc. Plus
things like either voltage sensing or a timer circuit
to stop the charger before the battery explodes.

Also reverse connection circuits are very important
but this part I will admit could prove to be interesting.
Protection on all three stages as follows.

Stage 1 = Block transformer with external connections
coming to the outside of the box for trickle charging and
battery forming 1-4 amp max.

Stage 2 = Osc section reverse protection with separate
external connections coming to the outside of the box
for separate connections directly to a small battery needing
some cleaning

Stage 3 = Cap dump reverse connection protection.

Not really that sure how to do this. I want learn how so
when I finish the 800 watt unit I will already know what
is needed.

A few pictures.

Transformer Done

Finished my transformer build from scrap MOT core material
and frig auger motor spools of 22awg wire. The upper coil
is 20awg wire with all the voltage ranges I need.

This is great for my forced Oscillators to i can turn down
or up the voltage to best suit the battery pack being
charged.

For instances if I am charging a 6v kiddy car battery all
evening I would select the lowest voltage setting to
feed the Bedini forced Oscillator so my caps get
the good stuff bringing the dump up to 15vdc before
discharge takes place. 1 pulse every 5 seconds all
the way up to 3 pulses per second.

This is standard practice for charging battery banks
using these tools properly. A 24v battery pack would
require that I turn the voltage up close to 24v to feed
the Oscillator for reduced charge time and over
amp draws on the input of the oscillator.

The way I charge a 24v pack is to feed my
oscillator circuit 36volts so it can make radiant
to boost the voltage to 50-60vdc for the cap
dump.

If you wait long enough between pulses you
can let it hit the 24v battery with 60volts
all day without any heating. Or all night.

A 5-10 hour timer is good to for saving your
batteries for speedy charges, just in case.

This design runs at 50v @2.5amps MAX and only warm
to the touch with no fan. The reason I mention a fan is
because this tall and thin design leaves a place for air
to pass over all three spools during operation unlike
a standard transformer.

Very easy to take apart and rewind as needed.

e-cores

Hi Mike,

Do you have a simple diagram of what you have there with the 2 e cores and the 3 coils on them?

[BroMikey]

Hi Mike,

Do you have a simple diagram of what you have there with the 2 e cores and the 3 coils on them?

You mean like this?

[BroMikey]

This was the intention. Use the two 40 turn taps to run the low voltage controls and be unaffected by the load demands of the Oscillator section.

Even though regulators are used the supply voltage does not change.

The 15v+15v+15v tap voltages on the Oscillator side vary slightly during
loading.

[BroMikey]

The air core coil as shown was only good for very small inputs of say 100ma with excellent high
voltage production. This coil is good
for something like a solar panel out back
that does not give alot of power.

I need more sometimes so here is what i did.









I got out my winder after splitting this 140-150 f
oot coil into two halves.






So the above coil is gone now and looks like this.














The operation runs very cool up to 2 amps directly to a battery
not to be confused with running to a cap dump. No heat in the
coil this time and the transistor runs at
97 degrees @2amps X34.5vdc

So what you are looking at is a 6 strand wind all going to a
single MJL4281A SG oscillator circuit. And one trigger winding.

I pushed a set of completely dead scooter batteries up to full
over night running 1ampX34.5vdc. Batteries are 12ah each.

The Transistor ran at 89 degrees all night.

Here are a few more pictures of my E-Core transformer.
Who knows maybe I could just pulse this transformer and
have an additional meaning of powering experiments.

[BroMikey]

I decided to scope the secondary taps while they were connected to a fwbr running a load at 3 amps 50vac and 40vac @2 amps and 12vdc

I have a .025 gap in the ecore.

I will post the waveforms when i can get them processed, maybe this is normal but the 50vac looks like a square wave.

Coming soon

[BroMikey]

Here are the waveforms for my ball of wire secondary

Some of those windings are out of line but it works for now.

I have no idea what I am looking at but keep in mind I have a slight

gap between the E-Cores. The unloaded waveforms are all by

themselves and the double wave shots are loaded but scope shots

are all done on the secondary ac output taps 12vac, 30vac, 40vac,

50vac and as the voltage increases the waves get more erratic.

If anyone who runs a scope can tell me what this is, I would like that.

[BroMikey]

Here are a few more

[BroMikey]

It is very difficult to express these scope shots with words. The AC sinewaves are in fact almost square waves. I think the .025 air gap in the E-Cores change everything.

I am going to connect this to a FWBR and the circuit will never know the difference.

Progress report for industrial grade Oscillator and capacitor discharging unit.

I will enclose a few pictures.

Also first, I will show you this protection circuit from another site known as

the "CROWBAR"

Anyone building boost converter circuitry must have over voltage

protection to ensure the longevity of the device. My coming posts will

center around protecting your circuits to make them a practical tool.

The circuits I will employ will be simple and effective, step by step.


SCR Overvoltage protector, crowbar circuit, #1

[BroMikey]

I have built many
Bedini SG oscillators to date with most of the devices ending
up in a trash can at one time or another because a battery
had some anomaly that caused it to become
disconnected from the circuit for a few seconds.

This caused the voltage to rise and burn out my transistor.

In order to protect my oscillator I must add controls that
stop this from happening. Most of what we see and here
around the world wide web is how the builder burned out
all of his 10 pole devices in one shot for a variety
of reasons leaving the machine a wreak.

Generally a 10 pole is so expensive that you
would expect the builder to have some kind of
voltage protection other than neon's, but this is not
always the case.

A lot of builders have an aptitude for mechanical
machine building, while their electronic abilities
need more polishing.

I have burnt out dozens and dozens of devices as
well, during single transistor operation. It is time to
push forward.

The circuit below is intentionally made simple.
Pic controllers, Atmega's and the list go on.
This is another subject that leave many of you
behind because you may not have had the college
education and learned the code languages nor are
you interested.

I have noticed over a 40 year period that for
industrial applications corporations will chose non
computerized controls for many reasons.
Put in a nut shell a computerized controller is
much more vulnerable
and can not sustain much vibration, humility,
high heat, and other
conditions which cause
premature failure.

The question comes back like this
"How did we add before calculators"?
Or "how did we get any electronic control
on a circuit before computerized chips came"?

Well that is a good question and this is where we
can come together on a functional very basic
circuit that has done the job for decades just fine
WITHOUT a computer.

The circuit is not finished but gives you an idea
what to do. Each time the battery voltage rises
to the preset value, set by the variable resistors
shown in the circuit diagram, a resistor drops out.
This dropping out, raises the resistance in the trigger
circuit, slowing the charge rate down.

Then at the end of the cycle (when you are not looking)
and the battery reaches a full charge the trigger is
disconnected, effectively turning off the
ENERGIZER/CHARGING circuit.
