Tesla inspired. I believe it.
Please confirm, you're producing 160 kW?
8000 V x 20 A?
That's enough to power 160 homes.
Waveforms greater than 11 kV peak. Don't know about components surviving that.
You might rectify your 35 k AC in an alternating manner at 60 hz.
146 pulses positive, 146 pulses negative. Tailor pulse amplitudes to resemble a sine wave.
More stages may be required until...
To step it down to 120 VAC you'll need a large transformer. Or two transformers. Big as a refrigerator. Just like the electric company uses.
You might find the electric company is willing to buy juice from you. They could tell you what voltage, and where, etc., they would hook you up to their transmission lines.
