Soft Starter for 3 Phase Induction Motors- full lecture!

The soft starter serves as a start-up aid for 3-phase induction motors. Based on the principle of Phase Control, which is a method for power limiting, applied to AC voltage, also known as “Phase-fired control” or “Phase Cutting”, the power of 3-phase induction motors can be reduced to get a soft start or also a soft stop.
