RESONANCE EFFECTS FOR EVERYONE TO SHARE

[Groundloop]

@wattsup,

I will help you out with a circuit for your swing generator.

The output is reversing polarity. You explained it right.
The input DC voltage will be on the output connector
with a alternating polarity at each pulse to the switch.
(Or half the frequency in the first version.)

The voltage rating depends on the transistors used. For the first circuit the IR2103
can take 600 volt at maximum. So if the transistors can take the same then this is the maximum.
The current can be high at low voltages but not at high voltages.
The transistors used will set the maximums. The data sheets for the types used
will explain how much current you can draw at a selected voltage level.

For the newest switch with optocouplers then the maximum voltage the switch can handle is 300 volt.
This because the H11D1 can take maximum 300 volts. The current can be high at low voltages but not at high voltages.
The transistors used will set the maximums. The data sheets for the types used will explain how much current you
can draw at a selected voltage level.

I will never recommend using the maximum voltages. The newest switch will be happy at up to 250 volt.
Above that, there is no way to tell when things blow up.
At maximum voltage the transistor used in this circuit can handle 0,1 ampere.
At 12 volt the transistors can handle several amperes. It all depend on what type
transistors you select to use.

The switch will produce an alternating DC output. The output is not a sinus wave
but square pulses. The pulses is even looking at low frequencies but "nasty"
looking at near the maximum frequency. The estimated maximum frequency is set
by the switch time for the optocouplers, in this case approx. 250 KHz.

The function generator looks OK to me.

Attached is the HW design files for both boards. I have included the gerber files but
the drill files are in millimeters. You can download the free Cadsoft Eagle CAD and
redo the drill files for inches if you like.

I'm not electronic engineer so please bear with me.I think we need more then 300V.Maybe 600V is even too low.Personally I would like to test an LC oscillator with 1000V and really microamps.The problem is with switches, there should be kind of intelligent spark gap (=transistor) to handle it.In other words : something which charge capacitor and then when fully charged cut power source and allow for freely oscillate the LC circuit.
There is one more problem I think. To cut all lower frequencies charge to capacitor must be flowing when capacitor is disconnected from coil or when capacitors are in special configuration. That's how I think about it but I may be wrong. I just use the water pump analogy - if capacitor is a water storage device then the size of it and the speed of water flow determine if water is slowly filling container or a part of water is flowing above container inlet due to speed.

Hi everyone,

I was away since last evening and just now cough up with the new posts.

WOW Grounddloop!!! ... thank you ever so much for taking so much of your time to reply and explain with such excellent details

You even went past the technical stuff and spoke from your heart ... you are a great soul and I thank you from the bottom of my heart.

I have truly been blessed to have all your help, since without your circuit I only had mechanical relays and could not confirm an effect like the one we have now.

Thank you also for continuing to develop the circuit to the next level.

I've been blessed with a financial donation to which was just enough to ordered the supplies needed to build a multiple coils and batteries self charging setup as you proposed.

I am truly thankful and humbled by all this great help

Hi forest, thanks for your post ... you are understanding well    The usable power output (Watts) gets higher as the polarity switched voltage goes higher ... and at a fraction (if any) to amp consumption.

It can also work the other way I demonstrated by using a fixed voltage output and adding more coils and pickups.

I do agree that the way to go is more voltage and I am sure as we share test results and develop the switch we will get there but to do this we need builders and developers.

Hi Luc,

I got a PM from "najman100" and I have proposed a deal with him. If everything works out
then there will be PCBs for both the new circuit drawings. Since I'm in the xmas mode
right now, there will be a fully soldered and tested PCB for the micro controller version
for you next year, for free. I will have the new PCBs and parts by January 16 next year.
If "najman100" agree to my proposal then there will be a PCB for you for the non micro
version also. :-) I have ordered enough boards so "Wattsup" and "TinselKoala" can have
a PCB for free also (the micro controller version).
