Voltage unbalance can be troublesome for motor circuits especially motors that are fed across the line. Voltage unbalance in VFD fed motors also lead to current unbalance but the difference is that phase with largest voltage will carry the most current hence the VFD load has a tendency to slightly mitigate the voltage unbalance.

VFDs, when fed from three-phase input voltage, convert three-phase AC line input voltage to a DC bus voltage, then take the DC voltage and convert it back into an AC waveform for the motor. In the event of a single-phase application, the high-level process is still the same, with the VFD converting AC to DC and then back to AC.
