Double pulse

Thanks John,

I know this is not about "whats in the box", but I started the mini wheel up the
other day and since I made a few small adjustments. I picked up this scope shot
while I was slowing down the wheel with my finger, and am not sure as to what
is happening. Looks like two, pulses. I did put slightly large neo's behind the
ceramic's than the ones I had in there.
Also there is no sound.. don't know what is going on. But if any one can shed
some light on this, thanks.
That's a 63V 22000uf cap and the input was at 30 v and .23 amps.
You can see how fast the cap is dumping.

Box

John B,

Very NICE!!!

Just so you know, I am not here questioning the truth of what you say about your lifes work, I am merely trying to better my understanding. I get the impression that you think we don't belive you. It is that you are light years ahead of most of us. Doing my best to try and keep up!


Many thanks, Brent

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

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

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.

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.

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

I dont think so

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...

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.

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 :-)

Patrick

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.

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.

@ 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.

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?

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.
