One man in one forum made selrunner, but with 3 w led bulb 220 volts, but it light on 100 volts. He say that most inportant is LC circuit and generator. And that very hard find exatly needed frenquency. Need with two potiontiometers for example 200 kiloom and 20 kiloom for tune. But very hard find needed frenquency.

  Many of the 220v 3watt bulbs can be lit on 110v.  The car 12v potentiometers can also be used when working with 12v input sources. They don't burn out as easily as the smaller trim-pots can. Small variable capacitors can also easily fry, and may be hard to replace when looking for the heavy duty ones for higher outputs.
  But, if the guy had a self runner, that is unusual. And, that it's not easy to find the right frequency, is also becoming more known each day, which is not making it any easier to obtain the needed results.

    MenofFather:
   Might be a zener diode, but might not be, also. Why are they facing towards each other? Is this really a common way to protect the Fets?  I don't use Fets, so I don't know...  As they can easily fry out, especially when allowing  them to get the high current back emf pulses 1:10 to deal with, as Ismael is mentioning. They are fast switching, but are also weak. Seams to me that special high current and high voltage diodes are what is needed.  No?

Nick,

A typical max mosfet gate voltage is 20V, so zeners are used to protect from transients in either direction that could damage the mosfet. These are typically rated at 12V, 15V or 18V breakdown.

  Yes, thank you.  But my question is why are the diodes facing each other? Is this typical, or not?  And if not, then what does that mean? Are they helping to make the charges buck each other, or just to protect the Fets?
Because, if there are not opposing primary coils, then this may be another way to obtain the bucking mode objective. Or not?

Evening Hoppy.

How do you think a Zenner would stand up to crowbaring for the Ismael device? If you were able to bring up the voltage to just around the threshold of reverse it would conduct for a short period of time before going back to blocking as the sine wave decreased. Just a thought

Cheers Grum.

Take a look at page 2 of this link to this data sheet of a mosfet that has an inbuilt back-to-back zeners plus an explanation of their purpose.
