How to maximise SSTC efficiency?
« on: May 07, 2020, 03:49:56 PM »
I want to make a (DR)SSTC powered solely through a USB C port (Capable of delivering up to 20V at 5A), and with a secondary coil no larger than 10cm x 10cm. How could you maximise spark length given these parameters? The coil doesn't have to be operating in CW mode, but it does need to have a break rate higher than 100 Hz.

I would think I should use a DRSSTC with a full bridge of GaNFETs or SiCFETS. To power the bridge, a boost converter could be used to step up 20VDC to 200VDC. What other techniques could I use to maximize spark length for a given wattage? Maybe I could utilize a 3 coil Tesla magnifier topology.
Anything can be a conductor if you pass enough voltage through it!

To get the biggest sparks, you can build a large TC then instead of using mains to charge up the capacitors use a boost converter. Not sure if you can run it off a 100W supply though.

100 Hz break rate and only 20V/5A will not give you any remarkable spark length.

If you took it down to something like 1-5 Hz break rate, you might be able to get a decent spark length by a boost converter into a regular mains powered circuit for a SSTC or DRSSTC.
