Hybrid Multicarrier Random Space Vector PWM for the Mitigation of Acoustic Noise

The pulse width modulation (PWM) inverter is an obvious choice for any industrial and power sector application. Particularly, drives benefit from the higher DC-link utilization, acoustic noise, vibration standards. Many PWM techniques have been proposed to meet drives’ demand utilization lower harmonics suppression noise reductions. Still, random (RPWM) best candidate reducing noises. Few RPWM methods developed investigated AC drive’s inverter. However, due randomness of multiple frequency spectrum, drive still challenging. These PWMs dealt with spreading harmonics, thereby decreasing harmonic effects on system. these are unsuccessful at maintaining utilizations. Existing less need complex digital circuitry. Therefore, this paper mainly deals a combined principle in space vector (SVPWM) generate generation using asymmetric multicarrier called (MCRSVPWM). he SVPWM switching vectors different carrier chosen aid bi-nary bit generator. MCRSVPWM generates pulses randomized triangular (1 4 kHz), while conventional method contains position fixed carrier. capable eradicating high-frequency unpleasant more effectually than shorter range. simulation study performed through MATLAB/Simulink 2 kW asynchronous induction motor drive.
