Volts on the caps attached to the output -- right, Harry? But the signal generator is still hooked up, and it's coupled to the output (at least) through the gate capacitance of the FET and the linked inductors of the "transformer", and the signal generator's output power hasn't been measured or even estimated. So, there's no reason to believe this rig is doing anything other than transforming and rectifying the output of the SG. As I've already said a boringly large number of times, this is the same general sort of system as Stiffler's circuit, where he had a signal generator capacitively coupled to the system, and it was driving a handful of LEDs. The main innovation here comes from Naudin, and it's the use of a toroidal coil as the primary with a neo magnet on the outside of the coil which "twists" the core's field to allow the toroidal coil to "couple" to the pickup coil. > > 2010/3/20, Harry Veeder <[email protected]>: >> yes. >> You are aware that the the voltage keeps rises even after the battery is >> disconnected. >> >> harry >> >> >> >> >> ----- Original Message ---- >>> From: Michel Jullian <[email protected]> >>> To: [email protected] >>> Sent: Sat, March 20, 2010 3:59:08 AM >>> Subject: Re: [Vo]:circuit diagram >>> >>> What do you mean, the inductor (10 turns of wire on a core) >>> is >> connected between the positive end of the supply and one end of >>> the >> switch (drain of the MOSFET) isn't it? >> >> 2010/3/20 Harry Veeder >>> < >>> href="mailto:[email protected]";>[email protected]>: >>> The toroid >>> is also wired in differently from the inductor in the wiki diagram, but I >>> suppose that doesn't matter either? >>> >>> >>> >>> harry >>> >>> >>> >>> >>> ----- Original Message >>> ---- >>>> From: Michel Jullian < >>> ymailto="mailto:[email protected]"; >>> href="mailto:[email protected]";>[email protected]> >>>> To: >>> >>> href="mailto:[email protected]";>[email protected] >>>> Sent: Fri, >>> March 19, 2010 1:42:52 PM >>>> Subject: Re: [Vo]:circuit >>> diagram >>>> >>>> The capacitor on your photo 2 is in parallel >>> with the battery so it's >>> part of >>>> the converter's input >>> supply.
