Why Single Phase to Three Phase VFDs are used?
In the condition when you want to control three phase motors (220/230/240V rating) speed with single phase 220V / 230V / 240V power supply.

Can I use single phase 220V VFD to control three phase 380V, 400V or 415V motor?
No. VFD can output variable frequency (0 to 400Hz), and variable voltage (maximum output value equal to input value). But can't boost voltage from 220V to 380V.
