For DS8, and any other members who are interested in the schematic and some photo details.
For the tank Capacitors it is better to use a lot of Capacitors in parrallel, better with current sharing and heat dissipation. ( I used here 1 x 470 nF and 8 x 47 nF in Parrallel ) The 470 nF gets hot when run at 24 Volts for a longer time.
Keep the leads short between this Cap and the LOPT 5 + 5 or 6 + 6 coils.
The coils are wound in the same direction with a centre tap. e.g. 10 turns with centre tap makes 5 + 5.
Wire size I used here was 1 mil². running current about 5 Amps at 24 Volts.
The red LED is an indication, so I know the coil is oscillating. just 2 turns a LED and 1 k.Ohm R in series.
I use this driver now to power a simple Tesla Coil which works very well.
( I will make up an other thread with more details if members are interested. )
During testing, especially first test run, put a 12 V 50 or 100 Watt car head light in series. saves blowing up the mosfets in case of a wiring error.
A 10 or 16 Amp HRC fuse is also good to fit in the positive line.
