Anyone try to collect the BEMF froman inverter?

Hi Gyulasun

I was thinking of using a small AC current driven through a NE2 rather than a filament type bulb to switch the circuit, but after reading more on the circuit in the patent and blog notes which mention using a FET capable of a couple of Amps the NE2 probably wouldn't be the best option either.

"I ran across a statement somewhere on the web where it mentioned using the circuit with AC to make it more efficient so I looked at it earlier today and was wondering if we couldn't replace the FET in the diagram with AC for switching the transformer and using the BEMF."

>>Having a variable frequency AC input across where the transistor would have been would probably allow the experimenter to tune the circuit at the resonant point.  A square wave generator may also work, if the circuit resonds predictably and reasonably.

But I remember seeing on a European experimenter's site awhile (several years) ago that if a circuit cannot charge up or recharge the power source that powers it, then it's not overunity.  Does the inventor claim this circuit does that?


 

"If one was to place a light bulb driven by AC input where Q1 is wouldn't that act as a switch at 60 HZ?"

>>Electrically, the concept seems sound to me.  A sine wave or square wave would seem the same to a resistive filament.  There's also the safety factor of having a visual indication that the circuit is behaving in a fairly normal way.
