A soft starter is a solid state motor starter that is used to start or stop a motor by notching the voltage waveform, thereby, reducing
the voltage to each phase of a motor and gradually increasing the voltage until the motor gets up to full voltage/speed all at a fixed frequency. The profile of the increase of voltage depends on the application. The voltage is reduced and controlled by 3 pairs of back-to-back , which are a type of high speed .Yaskawa ac drives A soft starter takes the place of a contactor and can also take the place of an overload relay in a standard motor starting application.
