Thanks Vortex1,  thanks verpies   

for your feedback, its much appreciated.

I will have to do some work/learning and try to incorporate your advices.

Regards Itsu.

Page 26 and 27 of theTL494 data sheet/application note that verpies posted shows a single ended design example running at 20 kHz and requiring 140 uH of inductance.

Granted, this is not the same circuit configuration as a forward converter, but should give some idea of where you need to be with inductance.

When he first turns on the machine  0:30 (  http://www.liveinternet.ru/users/edward_lee/post235237573/play ) the frequency is higher, then at the dotted line the frequency shifts when he turns on the nanopulser.

At some point he switches on the light at the power output , but there is no detectable change so I'm not sure where that is.

That is unusual because loading most types of pulsed inductive circuits increases their frequency since current in inductors rises quicker under load.

I've been away for a few days but will be finishing off the coil I started as close as possible to the Dally version. I'm fairly sure his 'green' transformer was a 50Hz mains type around 15VA, so this is how I will proceed with the build of the inverter. I already have a few home brewed transformer based inverters but I will try to keep as close as possible to his schematic. Between us, we should be able to discover if there is any unusual activity to be had from the two versions. It appears that Dally's coil winds are around half the length of the more sophisticated looking version.

That’s also my doubt why I asked the used of an ordinary rectifier diode on that green transformer’s output as well as the other rectifier connected to the output of them main transformer going to the 3 paralleled capacitors.
