In the quest to find a cheap or zero cost choke I tried one of these
from a 400W bay light. I rewound it with 8 1/2 turns, giving 50uH.
here is the inductance test.
Conditions have changed. 17V supply, 10.2mV /5.5A = about 2mv/Amp
yellow is gate drive, purple is supply, light blue is current
It seems to be good for about 75A
The inverter power I am interested in is 700-1200W power levels with peak efficiency
and capability to go to 3000W for short times. See following post for my rationale.
