This paper, present a soft starting of induction motor. At the time of starting three phase induction motor takes very large current and have low power factor. Due to high current, motor torque content ripples and transients. Due to transients and torque pulsation shaft of motor experiences jerk hence mechanical life of rotor reduces. In order to mitigate this adverse effect if starting current and torque pulsation in induction motor, a popular method is used which is electronically controlled soft starting of induction motor. Normally soft starters are used for avoiding this problems and soft start is achieved by increasing stator frequency. By using soft starter performance of induction motor is improved and also improved load torque characteristics.
