This paper presents a simulation, implementation and simplified implementation of the study and development of an induction motor equipped with a built-in sine pulse width SPWM inverter. PSIM software is used to simulate PWM switching strategies as well as basic problems that are less than THD, efficient use of DC bus, etc. Simulation is also concerned with minor problems like EMI reduction, switching loss, and fine harmonics distribution with optimum battery. The results used experimentally and in implementation proved the superior performance and effectiveness of the filter in reducing and obviously unwanted distortions.
