One is made with a 555, one is made with a single transistor, and one uses zero volt switching ? Give us a clue !What do you mean by "what's the difference ?"Steve
okay maybe a stated my question wrong, I know what the difference between them are and I have tested it. The question rather should be: Why are ZVS driver arcs hotter and able to be extended much further? also the colour differs. I have noticed that the single transistor produces alot of ozone and a long spark which starts out from further away than the ZVS. The 555 is a bit better if you get the frequency right and again its thin blue arcs that make a cracking sound. The ZVS only makes a high pitched whine when the gap becomes close to point where it will not be stretched anymore, appart from that its relatively quite. So again, whats the difference between them that they cause such different arcs?
+1 Hint, afaik, Steve is suggesting that you provide us with schematics.
Didn't you notice any difference? That would be the point in testing them wouldn't it? L
