Kapanadze Cousin - DALLY FREE ENERGY

Yes, but I didn't notice any effect, just the strong current vibrating the core (NMR, oh no!),

That's just magnetostriction or the slapping of two yoke halves and it does not have to be a bad thing.

Can the 18v Zener be replaced by a certain value capacitor, or another type of diode, instead.

Perhaps by a string of lower voltage Zeners or a low voltage TVS diode.

  Yes, but I didn't notice any effect, just the strong current vibrating the core (NMR, oh no!), was just probably caused by a short circuit just before the circuit died.
  Can the 18v zener be replaced by a certain value capacitor, or another type of diode, instead. As I'm out of those zeners, for now.
I think that the fets may be ok.
  Or, maybe I can run the system on my 12v battery, like I did previously, using just the 12v zeners on the Mazilli, until I can order some more parts.
  I'd like to look into the effect that I showed on one of my videos, when lighting the 25w and 50w bulbs, just off of the Kacher circuit output, while running from a 12v, 2.5A wall adapter.

Nick,

You would need to replace the zeners with zeners, or alternatively switch back to your 12V battery driven setup. If your mosfets are short circuit, you can confirm this using your meter.

Was it at 30V? Did it suppress High voltage successfully? Sometimes HV strikes me when i touch my metal pots for altering frequency and duty cycle. Even they are grounded!!! So i ordered some tvs at 30V@ 600W

Hi Jeg,

I used a 30V TVS to provide protection for my PSU, so that there was a good margin above the nominal 24V supply voltage. When subjected to a series of high voltage transients, the pulse currents can quite easily destroy even a 600W rated TVS, so a low value power resistor can be used in series with the TVS to limit the pulse current to a safe level, whilst clamping the peak transient voltage to a level that is within the max rating of the components being protected. If the TVS diode(s) are protecting transistors or mosfets then the TVS clamping voltage needs to be chosen at a good margin under the safe maximum voltage rating of the component(s) being protected.

Thanks Hoppy. I hope this will solve my problems permanently. Do you have any suggestion on what value resistance to begin with?

Jeg,

This is best practically done by using a few hundred ohms and then monitoring the temperature of both the TVS and resistor to ensure that it stays well within their ratings. However, the resistor may not be needed, so first just monitor the temperature of the TVS without a series resistor.
