Solid State Bedini

[Druide]

Michel

I do not use neons because I have not found them very effective at high power when using multi power strand chargers. I use transient voltage suppresors (TVS diodes) rated at around 188V (4 x 47V devices in series) directly across the charger output to ground. The thermal switch is bonded onto two of these diodes. See attached schematic which shows how the TVS diodes are connected to the charger output.

On power-up the transistor is biased hard on via the trigger winding, VR1, R1 & R2 to start oscillation. This gives the necessary very fast leading edge pulse every time the transistor switches on. This is a blocking oscillator and works differently from the solid state energiser shown in the FEG book.

The junction of R1/R2 (trigger bus line) is extended to feed the trigger to additional power transistors / strands. These are termed 'slave' transistors. The first transistor shown in the schematic is the 'master'. The base of each slave transistor is connected to the trigger bus line via a current limiting resistor the same value as chosen for R2.

Hoppy,

Would'nt it be easier to use one big TVS, 200 V or so, instead of four smaller ones or is there a particular reason to use four ?

Thanks !

I don't mean to be rude or anything, but why is it that every time someone with a decent working device, for some reason can't show us the schematic. I understand wanting to protect copyrights and stuff, but isn't this forum suppossed to be a place where people help each other and not just say "I know how to do it, but I'm not telling you."

There are lots of very helpfull people here, but sometimes I just get frustrated with all this rubbish.

Sorry for my rant.

I know its frustrating but you need to realise that people have received warnings about posting patented Bedini circuit schematics on forums not controlled by JB and his colleagues.

No problem with a 200V device. I used 4 x 47V diodes just because I had plenty of them surplus. The collector / emitter breakdown voltage for the MJ21194 is around 250V, so I would not go much over 200V.

I thought if something was patent that you could post and make it as long as you dont sell it in any way. But what do I know.

Hi Hoppy , your writing style is similar to a person named Clive i know is that you?

Now Rick and John don't mind if the patent drawing is being shown, just don't post a schematic that is copyrighted from the FEG book

Exactly my thought. You can build one for yourself, but not for commercial use. Besides, the reason these techs are not in wide spread developement and in use by the public is because everyone is thinking "how much money can I make" and not "how can I help the planet". The very reason why Stan Mayer failed to get his tech developed.

Anyway enough of the off topic. I am gratefull for what info we have been given.

Hi Ash

Yes that's me.

Thanks for your comments. I received a personal warning for just talking about the FEG Page 46 circuit in a technical manner and did not even post the schematic, so you will understand why I'm reluctant to post a schematic containing any complete Bedini circuit and discussing it in detail.

Clive

[Mark]

Wow, It seems like I talked about it more in detail than you did and no said anything to me.

[Druide]

Thanks again Hoppy, your explanations are realy clear, even though I don't know much about electronics, I'm pretty sure I get it.

One more thing, what about the bus that comes down from the "X" mark and crosses the ground bus, does it connect somewhere else ?

I have 16 power strands in 4 groups of 4. The 22R resistor shown serves 4 transistors, so the trigger bus line connects to 3 further 22R resistors to serve the other 3 groups of 4 transistors.

Clive

Thanks Clive ! It becomes more and more clear.

OK, then, I guess the (-) side of the charging battery and the other ends of the power / slave strands are connected to the (+) drive bus.

I have a 37000 MFD 75 VDC electrolytic capacitor, is it suitable for the PSU lines ?

Thanks again

Yes, just as per a normal SG monopole configuration.

Your cap is ideal for the power lines. I suggest you fuse your drive PSU / battery at about 10 Amps on the output side if you run at 24V with over 16 strands. Don't neglect this fuse as it could save you from a melt down if a transistor short circuits. This happened to me so I know the mess it can cause!

Make sure you have some big batteries if you use a lot of power strands. Golf cart types with 'wet' cells are better than big gel types but you probably already know this.

I can figure out what a mess a shorting transistor could cause with such high power !

I have four 100 A/h marine and three car starting batteries. I know that the car batteries won't last very long if I use them to feed an inverter but I've got them for free.

With all the information you have given us, I think I've been able to reconstitute a complete circuit schematic of your energizer. However, I hesitate to post it on this forum as I don't want to be harassed, sued, abducted, jailed, tortured and killed , unless you an other concerned persons give me the authorization to do so.

Once again, thanks alot !

Go for it! You will learn a lot by building and fine tuning to your specific batteries. I've spent the last two years experimenting with Bedini energisers adding all sorts of exotic add-ons and modifications but in the end its hard to beat John Bedini's basic SG monopole in a scaled up single coil multi-strand configuration, either rotor or solid state.

Your batteries may need a lot of conditioning charge / discharge cycling to lower their impedance in order to increase capacity, so once you have built the energiser think about how you can automate a charge / discharge routine using a C20 load (1/20th of the battery bank ampere hour capacity).

It will take a few weeks before I can get to town (have to drive 100 km for electronic parts !) to gather all the stuff, but until then, for those (if there are) who haven't figured it out, here's my schematic of Clive's solid state energizer. All the parts numbers and values are detailed in this thread. If I have it wrong, please correct me.

Michel

Correction : all the emiters should be connected to the drive battery negative.
Thanks Jetijs for noticing this mistake.
