Class-E and HFSSTC testing

[@Magneticitist]

Man I been so busy I need to catch up on this. That class E looks great though. I've been trying micro coils like crazy.. Winding, testing, recording. Then I lost a lot of footage. I must have wound 10 different micros. I did notice over time that some setups will run with the feedback winding flipped either way. One way seems to pull upwards of 2A then even more when pulling a beefy arc. The other way would run it at the preferred 100mA or so but the good arcs can still be pulled with the perfect primary location. I didn't realize this til testing too many coils with no luck.

well i got the hf circuit on hold till i can wind a coil for it, im getting my class E put together now but probably wont get it finished till sunday, its a real good, efficient circuit

@@dirkk82 I need to try to replicate that one too, where can I find the circuit for it? As for the other HF circuit I did notice something cool last night before passing out. One of my problems was heat mitigation at the micro size but I learned I can just jump from the topload of a main L1/L2 down into an 'auxiliary' coil and it doesn't make the circuit wonky. So basically I could house everything in a box with a fan on it and just run a wire out to the coil which would just be a plain coil at that point with no primary or feedback on it.

When you get close to the coil, you change the capacitance, that will change the resonance

[@dirkk82]

I know but it shouldn't throw the resonance so far out that the coil stops producing breakout, then again with this circuit, the frequency variation is only a 200 Khz difference so I must be adding quite a bit of capacitance to drive it way out of resonance 😕 not to mention this is a poor mans version of a class e coil, they usually have a fixed frequency but are very complicated to get tuned just right
