SvenIt may be that Hector has found local electrical work as there is still not much electricity in his country. People are desperate in places with no light, or refrigeration, according to information that leaks out, here to Canada.I have used 300 volt DC spikes to charge 12 volt lead acid batteries directly.However, the spikes were nearly zero amps.Do you have a voltage reading of how much voltage the spikes are delivering?You know my preferance for rectifying to dc, then causing motors to turn. If the voltage is too high, put more motors in series. To test amperage put loads on motors, such as belt drive them to other motors.If all of this seems awkward, remember this is just an experiment, and the motors are in effect, instruments, very sturdy instruments.If you can light light bulbs, you can heat water. Hot water is like a battery, and very predictable.Don't use led light bulbs. Use old fashioned energy killing clear incandescent types, if you can find any in Germany.I buy mine at the cheap little corner stores while they are available. Soon there may be import restrictions, and they may be unavailable.The beauty of using them, while so cheap, is you don't cry when you pop them like fuses.( if they "pop" you have been successful hah!)Again series and parallel these resisters.The nice thing about the tungsten filiments in them, they can give some cushion to pulses which when slower, you can see, and faster, well it can be useful as a poor man's oscilloscope.With such simple apparatus, it is not a big jump to practical devices for the home, or vehicle.I hope this is some helpCheers Warren

Hello Ole, Warren, Douglas and all,
Yesterday I experimented again with the Tranverter and found that you can watch the diode plug well synonymous of the input sine on the coupling capacitors on the diode connector page well.
The thyristors discharge very fast because there is nothing to improve even with 500 watts of load purely resistive load as a light bulb.
But you can modulate the signal from there as a sine well with the adjustable ignition of the thyristors. So that one receives short empty steps and lo and behold the input power decreases despite full luminosity at the output.
I wonder, can you load these spikes of the Pushpull transformer via a FWBR directly into a battery?
I tried to connect a 2 transformer in parallel but the impedance is so high despite a short circuited secondary that the thyristors can not turn off.
Then I switched 2 of the transformers on the primary side in parallel, then it just happened. It's pretty hard to work that way, it would be nicer if you can shut down the SCR appropriately, but they are almost indestructible to an IGBT or Mosfet. I also do not think that an IGBT can stand the high current increase unless it is pulsing fast.
What about Hector, is he swallowed up from the ground?
I feel that general topics are being relayed and project related information is not arriving. Somehow I have the feeling there is already method behind it.
regards
Sven
