what is the working principle of soft-starter & how it
diff. from VFD ?????????

Answer Posted / mehul.soni

A soft starter is similury of DOL & Star-Delta starter.
A soft starter does control for starting current.
Where as by using VFD,we can control both voltage and
frequency,so speed control is possible above and below Ns.
