Anther one of John Larkin's pencil sketches - no resistances, no
inductances or capacitances and part numbers only for the transistors.

And you get some hint at the switching spikes, which can be nasty.
It's an idea. If you want a finished design, write me a purchase
order.
The guy who contacted me already had an idea the Baxandall inverter would work. I'm still waiting for Infineon to come back to me with the Spice model of their IMWH170R450M1 so that I can send him a simulation.
I won't charge him for it. If Infineon doesn't come through soon I'll see if I can bodge an existing MOSFET model to match the SiC datasheet.
Whacky ideas including a Diac aren't going to open anybody sensible's wallet. The kind of gullible sucker who would vote for Trump might go for it.
