The objective is to efficiently evaluate u-resultants for numerical uvalues (such as over a finite field). The u-resultant of n homogeneous polynomials in n + 1 variables is defined to be the multi-variable resultant of these n polynomials and a general linear form in the same variables whose coefficients are represented by the symbols u0, . . . , un. It is shown that the u-resultant can be ext...

– The mathematical theory of resultants is used to compute the switching angles in a multilevel converter so that it produces the required fundamental voltage while at the same time cancels out unwanted order harmonics. Experimental results are given for the three DC source case. It is shown that for a range of the modulation index mI , the switching angles can be chosen to produce the desired ...
