Soft starters of induction motors are used in large number of applications such as blowers, fans, mixers, crushers, grinders, pumps and many other modern industrial applications. Voltage controller is the basic part of soft starter which is controlled to adjust the inrush current and developed torque. This paper presents a soft starter which is based upon soft starter of induction motor by AC pulse width modulation method the presented implementation gives satisfactory and promising results with PWM based controller. The presented approach can be used with off-line training as well as with on-line training and hence can solve the problem of on-line computation of firing angle.
