Reactive power - Reactive Generator research from GotoLuc - discussion thread

I've found I can run an incandescent bulb on the output of a car ignition coil (maybe 5000v, 1000Hz) at 40w, or an MOT (2000v ish), and it's exactly as bright as it is with 40w mains (at 240v AC, 50Hz). Just the same...

I was talking about a circuit with only the bulb in it, and maybe a spark-gap... Maybe I missed the finer points of the argument... Apologies...

Luc,

This online calculator yields 40nH for a 2" length of .05" diameter copper wire and a whopping 1440nH for the same length/diameter of nickel wire.

As your nichrome is a nickel chromium alloy, the inductance is likely different than that of a pure nickel wire, but it is very likely that your 2" of nichrome wire has a much higher inductance than the 40nH of a 2" copper wire.

Hi PW and poynt99

I'm away for a day, so can't do more tests.
@ poynt, I'm quite positive the probes are correct and I had just calibrated the probe and scope.
I think PW has possibly found what could cause this anomaly. Thanks for looking into this PW
I didn't think it was real, I was just trying to find out what could cause this.

Is there a test I can do just to test my nichrome wire?... like if I remove the coil would that do it?

Thanks

Luc

Hook up something that makes pulses with reasonably fast edges through a 100 Ohm resistor and look at the response.

Luc,

Before you change anything I would suggest one very simple test to prove if the 180º phase shift is due to the nichrome wire inductance or not, and that is to perform the same test at a frequency of 1kHz.

If the phase shift is still there, then there is a signal inversion somewhere. If the phase shift changes to what we would normally expect, then it is most likely due to the inductance in your nichrome wire CSR.

Sorry Tim. I thought you were talking in reference to Verpies video.
Ofcourse there is no rocket science involved with the schematic i posted-it was just a simple way to show that what verpies showed in his video,can be achieved in many way's. Ofcourse we know that G1 only has the potential difference in voltage from B+ to C1+,so the voltage is very low,but the current remains the same across the input side of the system as a whole.My questions wernt me asking for answers,they were directed at those who may have wanted answers them self. It's realy nothing more than a buck boost converter with a mechanical/electromagnetic trigger.
