Potential difference

BrentA929,
Yes I see you over at the Earth Lights all the time. Look I will open the box and show you what is in it. This is an easy one for this group as they are more advanced. I do not run that big motor much as it barley fits in my shop and the Chinese keep asking to buy it, but it's like a tooth of which I knocked out.
If you look at these DC solid state switches you will find that you can hook them up to self trigger in reverse breakdown. That is all it is, you guys should be able to figure that one out, that is why you only see two wires coming out of the box. The capacitor charges from the Bedini/Cole switch and then the fet breaks down. But if you really think about it a sidac hooked up to this solid state relay will also work. Just put your thinking caps on about what I just said.
John

Well I don't have the answer but I bet it has something to do with the difference in potential between the capacitor and the charge battery.

Big Bedini Motor

Hey John,

I am still hanging around and do frequent the Earth Light thread. Not something that I am really into, but probably more for the shear purpose to read what you have to share. You are wealth of knowledge and are an inspiration to many people. My wife calls it a "man crush." I don't disagree with her, I would be a fool to. I love my wife very much!

Now with all the awkwardness out of the way...

I feel like I may have bitten off more than I can chew with my BFW build. There seems to be so many pieces to the puzzle that I just can't see and more important not sure if I would even know it if I did see it! I am fascinated by this technology, but it seems that so very few people actually know what it is or even know what they are looking for. That's me! Not even sure what I am looking for. I just know that there is something magical, maybe even mystical that draws me to this stuff. Maybe it is just the challenge of trying to figure out this riddle. I read as much as I can on the groups, attend the conferences and more importantly build as much as I can. I continue to learn and appreciate all that you do for this industry!!!


None of us would be here if it wasn't for you!!!

Thanks for all you do and share,

Brent


P.S. Hell yeah! I think I speak for everyone when I say that we would love for you to open the box and show us what is inside!!! Hooah!

John,
This is how I've been doing it for a while now.
although I like to use the MJL w/o the relay for my generator coil.

The BOX

I will try to remind John later about the box and take a picture or ? and post it or john will post it.

Inside the "Box"

Brent, I agree a peek inside the box would be worth a thousand words!

Thanks JB!

Patrick is that a hybrid SSR?

Whats up with our wifes and John B

Brent,

I have the same kind of thing with my wife and John. She doesn’t pay any attention to most the things I watch, read or build. But I put something of Johns on and she will come over and watch with me. She sz that he is a very intelligent man, you can tell by his sexy voice and dark eyes.

WHATS UP??? I guess john is some kind of Chick magnet. A wild and crazy guy.

All in fun. Thanks john for all you do

What is in the box

@ All,
You are going to be surprised when Chuck and I open that box as I told you all it is just an opto fet switch that just works by the breakdown of the fet. Easy one to do can be done with a sidac to fire the led in the opto fet switch. But I guess I must open the box for you all to believe me. Chuck and I will do it tomorrow for you all. You guys are smart here and should understand what I'm saying. The capacitor just charges to about 48 volts and the fet goes into negative breakdown and the energy is delivered to the secondary batteries as the coils fire. Come on guys the Sidac does this easy with an opto fet dc switch. no real power required.
John B

[BrentA929]

Can't wait

John B,

I'll be eager to see what you show us tomorrow!

48V? You didn't just say that!?! All this time I thought we were charging to double the battery voltage, which would be 72V. Its no wonder my hair is going grey...


Thanks, Brent


@Ed - BTW and I'm not sure why I am clarifying this, but my wife thinks I have the "man crush." Energy this, energy that and John Bedini this, John Bedini that. Sometimes its all she hears about. Oh well...

John,
This is how I've been doing it for a while now.

Patrick

Oops, I jumped the gun on my drawing. the way I've been doing it is w/ a mechanical relay as drawn. it fires the relay when the transistor breaks down, I have the second mjl EC backwards in the drawing.

the way I would like to do it is w/ a solid state relay minus the second mjl.

when I use the mechanical relay w/o the second mjl, the relay eventually freezes :-)

here is the corrected drawing, that is a mechanical relay.
also, on the lead in MJL I can add more in series to increase the target voltage.

I dont think so

Brent,
Remember what I said about the capacitor, it's rated at 65 volts 75 volts max serge so you can not wait for it to reach that voltage as the switch breaks down before that, But look in the box. The high voltage destroys that cap 72 volts would be double and that is too much for the switch at that current of 5.2 amps which is 374.4 watts. The machine was only using 1.5 amps at 36 volts or 54 watts Did you not watch the meters at the conference. When the meters were pegged after running the current was down on the secondary batteries to 3.3 amps at 48 volts or 158.4 watts float. and that makes the batteries standing at 16 volts

But your correct about doubling the voltage for a battery. So why would you have gray hair over this as that is where the machine was running. I ran this machine two times and it was at the same power level both times. This is what I have in my notes on this machine. I would have liked to have double the voltage as I have always said, not with that switch. You only need to be two to three volts over the battery to charge them but you really want to push them to 15.5 to 16 volts max or the power is just being wasted in heat in the battery. Even Ricks SG 30 coiler was only pushing the batteries to 16 volts. John K even turned it down to not over boil the batteries.
But just look in the box and you will see, go get your hair dyed your wife will love you as a new man.
Damn I should have opened the box for John K when you were here.

The Box

Brent,
Ok here is what is in the box just as I told you.

http://www.johnbedini.net/john34/thebox.wmv

Anything else here?. As I said your machine should work with a number of variations. You just need to stop looking at things one way as if this thing came out of some text book. Back to my Crystal Batteries Now

FET Switching

Thank you John for giving us a look inside the box. We've all been very curious! Using the opto-coupled SSR package makes for very covenient mounting inside the box. Saves having to heatsink and mount a seperate FET plus you already have screw terminals for connecting to the cap and meter.

As usual an elegant design!

Thanks again,

Ron

Hey John,

Could you please post the part number of the SSR? The video didn't quite focus on it. I want to go look at what the breakdown voltage is. I'm betting it will be about 12v.

I tried a different way of doing this with an opto (H11D1) and a FET last night, but not in breakdown mode as the BVdss was too high on the FET. I could get it to switch on no problem at about 12v over the battery voltage but had problems getting it to switch off. But you had me thinking.

Also looked at SIDACs but most of the ones I found had a voltage range of say, 100v - 125v. Couldn't find one in the range we are switching.


John K.

P.S. You were right again with the FETs on the SSG. Great if you want torque with recovery, but the MJLs gave better charging but less torque. Will give you a call about it.

John K,

It looks like a Douglas Randall Model K08A or K12A. Its hard to tell. The K08A is rated 8A and 32VDC on the load side and the K12A at 12A. Each is described as a bipolar transistor switch. Not much more information available.
