A novel method of simulating the steady state performance of a generalized M-phase thyristor controlled bridge converter

A novel method for analyzing generalized M-phase mains or force-commutated AC-DC converter circuits is described. The method utilizes the switched-function modulation lemma. As a result, the computation process of AC voltage and current as well as DC voltage and current is systematized. The harmonic contents of these variables are obtained in the closed form. One of the main features of this method of harmonic spectral analysis is the saving in computational time achieved when the harmonic spectral analysis is all that is required. This is because the program separates the calculation of harmonic spectral response from the calculation of the time-domain response. Numerical examples are included to illustrate the technique.<>
