Use for the Tesla Switch

[rosehillworks]

At all
here is the diagram for my build.

No the cap just needs to be regular capacitor, 1 farad stereo type caps are nice cause they have some holding power with little to no resistance.
Those big caps aren't what you want. They are hard to charge and discharge cause of the High ESR on them.

Rockford Fosgate RFC1D Capacitor | eBay

I use an older equivalent.

The schematic is this one http://www.matthewcjones.com/power/SimpleSwitch.jpg.
Don't read to much into it its just an outline.

@all
The drawings of the switch's are taking some time so as soon as they are done I will finish up and compile the whole article.

Thanks Matt, looking forward to learning more on your experiments. Was there a video posted? What what the maximum output power on the large design?

Back in 1983 Ron Brandt claimed to run his car on his Tesla switch and up to 60 mph.

THE TESLA SWITCH

BTW the Maxwell Ultracapacitors have extremely low internal resistance (ESR) and consequent high cycle efficiency (95% or more) and extremely low heating levels. The biggest downside is the price, as to get 16V to 20V peak in the Maxwell ultracaps would be 5 to 10X more than that $70 Rockford-Fosgate-RFC1D-Capacitor.

How many of the Rockford capacitors needed? That one photo (see below) showed 7 capacitors?



Keep up the good work

Thanks to Matt it works

That build is mine. The out put is 3000watts. Matt was vary kind in helping me getting it to work!!! I hope to post some test soon. I did not used the right wire so I have to wind it again with #6 transformer wire. Matt is right about the heat in the transformer so use what he said to use.

The caps I used are 18,000 uf x 7=126000uf

Thank you William for sharing your research and results

Matt wrote that there are 2 transformers A & B below?

A- Transformer. 1 -3 KVA or 1000 to 3000 watts. BIGGER IS BETTER.
3000 Watts Step Down Voltage Converter

B- #6 AWG Square magnetic wire at 150 ft, OR #14 awg magnetic wire at 300 ft. Now you can use anything in between the 2 listed wire. But do not go smaller than 14 awg, and DO NOT THINK you can wrap 5 strand of 20 awg together to come up with that size. This a recipe for HEAT and does not work well. You cannot use insulated wire either, this is also a recipe for poor inductance.

Or you can use A or B?

If you need both, what do you wrap the 6 AWG square wire on, iron core or ferrite core? Toroidal core for high frequency? What is the frequency of the operation of switching?

I used a 3 KVA 3000 watt transformer with an iron core. Use the 6 AWG square wire on L1 L2 and L3. The transformer is the one that Matt has posted in his list

What type of core do you use for L1, L2 & L3?

This is it 3000 Watts Step Down Voltage Converter Get it disassemble it and rewind it with #6 AWG wire.

I gave you link to both the transformers I recommend. One is for a large setup one is for a small setup.
Stop drinking so much coffee and slow down when you read the shopping list.

NO FERRITE, NO TOROID.... Just plain old iron plate cores, for starters.

Hi Matt, the instructions didn't mention stripping out the wiridings on that 3kw transformer and winding the L1 to L3 coils on it with the 6 AWG square wire.

How many turns/length of feet of wire are for the L1 to L3 coils?

Cheers Mike

[Matthew Jones]

Thats because I haven't given the instructions out yet... Just a shopping list of parts.

Its all coming.

Matt,
I have been looking for some good switches for this project. What do you think about these

If they are a go, I found them here Powerex Result

Hi there Rosehillworks , Matthew , Bits and others ,
Nice work there fellas , Keep up the brilliant work . cheers Jason

Ya David those will work but you have to get the powerex driver kits for them. And don't fool yourself they'll burn up if you do not set them up right.

I will have literature to cover the wiring with those switch's,in general.

But before you run out and buy those you may want to just get a few small relays 50 amp or something to make sure you can get the thing wired up and running. Those big switch's with the driver are expensive and if you make even little mistake they go. Ask Rosehill
