I.I.D. stochastic analysis of PWM signals

Abstract: A stochastic analysis for pulse width modulation (PWM) is given. Under a discrete random generator process with independent identically distributed (i.i.d.), continuous, rangelimited samples, stochastic models for different PWM signals are proposed. Using randomization of the signal starting point, wide sense stationarity (WSS) of proposed PWM signals are shown. Autocorrelation functions and their corresponding power spectrum densities (PSD) are derived in terms of the modified complementary cumulative distrib… Show more

“…Introduction: There has been much interest in random modulation schemes for power converters, with reduced electromagnetic interference (EMI) as one of the main benefits [1][2][3][4]. To date all of the analyses of power converters driven by random modulation schemes have involved auto-correlation functions and power density spectra.…”
