Contents I. Introduction
The SPIM is the motor which is powered by single-phase supply. Supply is eagerly available to use but the motor cause inconvenience to produce rotating magnetic field, therefore, the motor is not self-started. For this SPIM has the auxiliary winding which has maximum inductance as compared to main winding and also has some phase difference to produce the phase shift of fairly accurate to 90°. And this phase shift is achieved with the capacitor/inductance in auxiliary winding. Using, this we shift the motor on two-phase for a while and then disconnect the auxiliary winding from the circuit. Then SPIM has actually come into action. This work is used globally with drawbacks. To improve these drawbacks of this motor firstly the two-phase supply is obtained from the various techniques. The Scott-T connection is one of them which then used to supply two-phase induction motor. As the supply purely has the phase shift of 90° the rotating magnetic field is produced in the stator core of the motor and motor is a self-started [1]. Another method is matrix converter which produced the 90° phase shifted supply for the two-induction motor from single-phase supply [2]. And the last method is by using an inverter. There are the different type of inverter like SVPWM and another is a carrier-based PWM i.e.
