Abstract

The prime advantage of non-deterministic Pulse Width Modulation (PWM) strategies is that the harmonic spectrum of the output voltage is spread over a range without any specific dominant harmonic. This absence of distinct dominant harmonics results mainly in reduction of acoustic noise and torque ripples in drives. In this paper, a Field-Programmable Gate Array (FPGA) based implementation and corroboration of Pseudo Random Binary Sequence (PRBS) bit based Random Carrier PWM (RPWM) for the three-phase Voltage Source Inverter (VSI) fed induction motor drive, are presented. First, a detailed simulation study on performance characteristics such as harmonic spectrum, Total Harmonic Distortion (THD), Harmonic Spread Factor (HSF) and power density spectrum, are presented for both conventional Sinusoidal PWM (SPWM) and RPWM. Secondly, a new circuit realization of the above PWM strategies are developed using state of-the-art FPGA technology. The designed controller provides a simple and effective solution for high-performance AC drives.

Keywords: Field Programmable Gate Array (FPGA), Harmonic Spread Factor (HSF), Power Density Spectrum, Random Pulse Width Modulation (RPWM) and Voltage Source Inverter (VSI)
