Development of performance characterization in VSI fed induction motor drives using random PWM

Any industrial or power sector application requires a pulse width modulation (PWM) inverter. Industrial drives in particular are highly concerned with standards. To satisfy the voltage source inverter (VSI) objects, variety of PWM approaches used, including DC input utilizations, suppression higher and lower order harmonics, as well spreading acoustic noise reduction, among others PWMs. One better for minimizing on threephase fed is random palse (RPWM). Despite fact that these described RPWM superior terms harmonic mitigation, methods unable to achieve target DC-link utilizations. As result, focus this paper combining multicarrier principles space vector (SVPWM) produce multi-carrier SVPWM (MCRSVPWM). The suggested generates unsystematic triangle carrier (5 kHz, 2.5 1.25 1 kHz) based pulses, whereas traditional techniques uses fixed frequency triangular generate positions. Asynchronous induction motor driving simulation carried out using MATLAB/Simulink. proposed MCRSVPWM put test 2kW six-switch VSI-fed drive system.
