Single-phase to 3-phase conversion
$begingroup$ You may want to also add that almost any inverter can be used as a single-phase to three-phase converter if you derate the inverter to 67% of its nominal rating. The derating is required because your rectifier diodes on the front end will be sourcing significantly more current than they would if three phases were present on the input, and also your capacitor bank will …
How to run a 3 phase motor in a single phase line using a capacitor
