Spectral Errors in the Application of Pulsewidth Modulated Waveforms

Possible spectral errors resulting from the application of theoretically optimized pulsewidth modulated (PWM) waveforms to physical power converters are considered. These errors, produced by commutation rise and fall times, timing errors, and amplitude ripple, are synthesized and analyzed in terms of switching, ramp, and ripple functions. Probabilistic and heuristic results show the relative sensitivity of the error producing terms independent of the PWM technique.
