Abstract :
Two classes of microprocessor-based random PWM (RPWM) real-time schemes for DC-AC power conversion are compared and evaluated. Performance of the RPWM schemes based on mathematical and logical approaches is examined. The proposed schemes exhibit excellent harmonic content with all low and high-order harmonics suppressed, and are suitable for both MOSFET and IGBT inverters
