Abstract: “This paper presents hardware comparative evaluation of different PWM schemes of three phase Z-source inverter by feeding to an induction motor. For purpose of comparison, all PWM controls are evaluated at same input DC voltage, same value of shoot through duty ratio, switching frequency. The comparison shows that the maximum constant boost control is the most suitable PWM control scheme for Z-source inverter.”
