Do VFDs really improve the power factor of AC motors?

When the motor is lightly loaded (bottom) the wave forms are out of phase (large displacement) and power factor is low Image credit Yaskawa America There are several methods of improving power factor in an industrial facility but when the main culprits are induction motors — especially induction motors not operating at full load — applying variable frequency drives (VFDs) is often the
