Pulse Transformation

02/20/2014 5:23 PM

I have been building and testing these schematics with the supplied parts Although I'm finding none of the circuits are working whatsoever. The aim was to achieve 50kv at 2.5 amps the three transformers given are 80kv 110kv and 115kv. Are there any persons who have build this or have tried similar. http://xrsdesignsystems.com/page48.html

You should have read this:

Free Support :

If you get stuck when trying to build your free schematic a basic level of support is given to beginners if required. This is a very simple circuit design to build but a basic level of electronics knowledge is required building or using High voltage.

and you should e-mail them: xrssystems@gmail.com <xrssystems@gmail.com>.

50 Kv at 2.5 amps?

The page you referenced doesn't appear to have anything capable of that.

I think it may be just as well that OP can't make it work.

How so ?? the lowest transformer is 80000 Volts With 3-5 amp input which takes volts 18^ The spark gap voltage should be 50000 Understand that I have no equipment to test the Emf. Theoretically this should be achievable with 7.2 Volt 5amp supply Step ups maybe and then a smart driver that produces the ignition On it's pulsed time while still charging the storage for the next cycle

Maybe you are right. Just off the cuff guess on my part; 125kW seemed excessive for what was pictured.

.

How long and how frequent are the pulses supposed to be?

Your link indicates:

Circuit Input power : 9v to 18v 3A to 5 Amp

Max input power 50 Watts

50 Watts divided by 18 Volts gives a maximum INPUT current of 2.77 Amps.

With all transformers, as the output voltage increases, the output current MUST decrease. (You can't get more power out than was put in). If there were no losses, the maximum output power would be 50 Watts. 50 Watts divided by 50,000 Volts gives a current of 1/1000 of an Amp (1mA). Since there are always losses, you can expect an output of something less than 1mA.

Now the last two paragraphs are presumably average power values. Since this is a pulsed system, the instantaneous currents can be significantly higher, but the rules of transformers still apply. 50kV * 2.5A = 125 kW (125,000W). Again, ignoring losses, the input power would have to be 125kW. 125kW/18V = 6,940 Amperes of input current. That's a humdinger of a battery!

A standard transformer capable of handling 125 kw weighs around 600-1000 pounds and occupies 10-15 cubic feet of space. I don't believe that is what you have purchased.

GA!,

It is nice to see that there are people who understand the laws of conservation of energy...

I have been building and testing these schematics with the supplied parts Although I'm finding none of the circuits are working whatsoever.

Based on the above statement, it seems you lack the knowledge nor the understanding of electronics? It is kind of dangerous way of learning, so what I would do if I were in your shoes since the pc board is not included in the kit is to first learn how to translate the schematic diagram that comes with your kit into a PCB form. When you successfully able to translate and layout the circuit components into the board level properly, you may find the completed printed circuit board may help start your kit to function...

Presumably the pulse is created by slow charge and fast discharge of a capacitor? And voltage multiplication?
