Abstract

A digital simulation technique based on single Fourier series is used to predict the spectra, including the nonintegral harmonics, generated by digital asynchronous pulse width modulation invertors. The results, with an accuracy of 70 dB, are superior to the results obtained with fast Fourier transform techniques, and offer an alternative to the complex methods based on double Fourier integration and Bessel functions. The technique is applicable to any choice of reference waveform. Output distortion with the introduction of minimum pulse and dead time is studied
