I am needing to convert either 240 V or 120 V single-phase into 120/208 V three-phase 4-wire. The load needed is 30 A. My panel can supply up to 100 amps, so the amperage isn't an issue.
I've looked into static inverters, but then I'm going to need a step-down transformer which just adds to cost.
I'm considering a VFD rated for 120 V single-phase input, 208 V three-phase output. Yes, I know VFDs are used almost exclusively for motors. I will not be running a motor, there is already a VFD in my unit for a motor.
What is the best way to accomplish this? Can a VFD supply three-phase AC for something other than a motor?
