Solid state tesla coil design? Answered
Well, I am planning to build a solid state tesla coil. I've already build a spark gap one, but the amount of control over the output offered by sstcs looks more enticing. I have been looking at many different designs, but I think I want to go with a design based off of Richie Burnett's sstc.
Those are the schematcs. The first problem I'm running into is that he is running off UK mains, which are double the voltage from the US mains. Will the output of the tesla coil still be good if I am switching ~120v through the primary as opposed to the ~240v in the drawing?
Would this mosfet (https://www.onsemi.com/PowerSolutions/product.do?id=MTW32N20EG) work in the power stage, or should i get a higher voltage/lower current mosfet? I also need a substitute for the mosfet in the logic stage. Does it even need to be a mosfet? Could I replace it with a transistor?
The regulation circuit also worries me. Doesn't a linear regulator need to be fed a voltage of at least 2 volts higher than the output in order to function correctly?
I just realized how many questions I really had about it. Wow.
EDIT: I uploaded the pics for the sstc. The first two are the ones that I linked to, the third is Steve Ward's mini sstc. I was deciding between which one to use, but chose Richie's because Steve's has so many ICs and seems to be over-complicated.
