The power board has been tested to start the air compressor.
11kW peak power for 1/4 second.
It passed easily.

3 FETS on the 4 legs of the full bridge.
No RC snubbers fitted yet. (I want to see the difference
they make, if any)

2 x 10,000uF 100V and 2 x 3900uF 80V caps on the DC supply rail.
This is not enough but good enough for me.

Errors fixed on the PCB already so we are ready to go.







I will do further testing then post the PCB files.
And basic build information for the inverter.
And the code and PCB files for the nanoverter.

Eventually I willpost here the complete information and files needed to
do what I have done.

I think it might be time to work on a simplified version of the nanoverter.
It will use only one nano, and have zero communication with the outside world.
We define the heatsink and toroid temperature limits for the fan and overtemp stop,
a low voltage cutout and away we go. Just ground a pin to run it.
I will call it the picoverter.
