Claim 2:
3. The method of claim 2, further comprising:
measuring a first set of voltages {Vc1, Vc2, Vc3, Vc4} of the capacitors (C1, C2, C3 and C4) of the multilevel converter;
determining a set of switching states of the first optimum voltage; vector (Vopt-1)
identifying four redundant switching states of the first optimum voltage; vector (Vopt-1);
evaluating the second cost function J2 for each of the four redundant switching states to generate the set of second cost; wherein
evaluating the second cost function J2 is based on J2=|vC1k+1−vC2k+1|+|vC3k+1−vC4k+1|for each k =1 to 61.
