Posted by Bert Hickman on 7/27/2006, 9:13 am, in reply to "Re: slovac tesla coil page" Oops - I went back and looked at the schematic and drawing for the bjt1, so I can now see that the inductors are actually driver and feedback windings that are also magnetically coupled to the secondary. This wasn't obvious when I looked just the bjt2 schematic before. This is why an English translation would have been useful... :^) Best wishes and play safely, Bert

The voltage feedback/phase-shift technique that you use on the bjt2 is interesting. Does the text explain the theory of operation? It looks like you are using a phase shifting circuit to provide feedback and support oscillation, but I'm not sure I understand why some components are in the circuit (such as the inductor connected to the base of the transistor and the diode to the left of this inductor that goes to ground). Does the transistor operate in the linear region instead of between saturation and cutoff? Best regards, Bert
