i think VFDs are next version of soft starters. In VFD we
can varry the speed from zero RPM to Full load RPM. and
come back from Full load RPM to zero speed very smoothly.
But in Soft starters starting will be smoothly but after
reaching the full load speed the Soft starter shall be by
passed and soft starter cannot be controlled the speed.
Cost wise VFD is more costlier than VFD. In reliability
point of vied VFD is better
