Abstract
A new random pulse-width modulation (RPWM) scheme which includes a weighted decision switching process has been developed and tested for inverter fed AC drives. The scheme combines the advantages of the deterministic nature of the standard PWM schemes and the nondeterministic, spread spectral characteristic of RPWM schemes. Test results have confirmed the improved spectral performance of the proposed schemes over a standard RPWM scheme.
