Abstract

The prime gain of this non-deterministic pulse width modulation (PWM) strategy is that the harmonic power in the output voltage, which is spread over the inclusive choice of the frequency spectrum, is not clustered at a specific frequency. The nonexistence of distinct dominant harmonics helps in the reduction of torque ripples and acoustic noise in drives. The effectiveness in acoustic noise reduction mainly depends on how effectively the non-deterministic characteristics (randomness) are being amalgamated in the PWM strategy. The goal of this paper is to check and implementation of two different topologies for validating the randomness of PWM based induction motor drive. The first topology is a random carrier PWM (RCPWM) with Pseudo Random Binary Sequence (PRBS) bit and is validated. Secondly, a sample exploration of random Pulse Position Pulse Width Modulation (RPPPWM) is made. Simulation is completed for this RPPPWM, RCPWM, and traditionalistic sinusoidal PWM (SPWM) and the performances such as Harmonic Spread Factor (HSF), power density spectrum, harmonic spectrum, and Total Harmonic Distortion (THD) are investigated. Hardware implementation is made using a Field Programmable Gate Array (FPGA) (XC6SLX45) SPARTAN-6 device and the upshots are verified through the VSI based designed prototype.
