Radiant power from Solid state Tesla hairpin circuit

[evostars]

C1=C3=1Uf they provide the fast current needed to run it. wima mkp10 or fkp1 or something like that but not elco (to slow)
voltage rating for power supply, 100Vdc

C2 is the series resonant tuning capacitor. it depends on which frequency you use. I have it from 35nF to 61nF
Wima fkp1 2000Vdc series. for L2
caps can be bought at reichelt.de

I actually use 4 coils.
L2 is the primary impulsed series resonant coil

L3 is the secondary coil, loose coupled to L2.
L3 can be untuned, or parallel tuned.

L4 generates output (depending on tuning)
L4 is close coupled to L3. L4 is not resonant
L4 can be rectified into dc cap for resistive load power measurements

L1 and L2 are also close coupled they are a feedback loop.

Im still playing with it. not fine tuned it fully yet, as it also depends on L2 L3 coupling (distance)

today I tested the halfbridge isolated gate driver pcb, without batteries or pulse transformers, and it works!

If the half bridge circuit has been tested, it will be made available

you will also need a symmetrical power supply, I use a 2 channel series connected powersupply for that.

and a dual signal generator, for out of phase square waves 49% duty cycle.

Oh and use the Mur8100e diodes, not the others they burn out,( due to soft recovery problems ) stth1210 are bad

still testing... still learning,
Kind regards

and to protect the mur8100e from over voltage, use a 900V SiC mosfet, so its 900 avalanche mode body diode will protect the 1000V diode

mosfet 900V

Video will be watchable from november 21 2020; 0:00 AM GMT

It shows my Radiant half bridge circuit. explained into detail, and working.

Hi peolpe!
I'm amazed by this work, so I've decided to build it and make some tests myself. I've designed a driver pcb for my taste, but the schematic is the same as Ivo made in the first turn.
The pcb was designed with diptrace, a very nice software for small hobby projects. Please take and use it! My only wish is if you notice some errors please let me know!
Thanks!

I found meanwhile a very useful description of the driver circuit design (see picture), so I revised my work, and corrected some errors too!
These will be manufactured probably...
