document: Steinmetz system design under unbalanced conditions This paper studies and develops general analytical expressions to obtain three-phase current symmetrization under unbalanced voltage conditions . It proposes two procedures for this symmetrization : the application of the traditional expressions assuming symmetry conditions and the use of optimization methods based on the general analytical equations . Specifically , the paper applies and evaluates these methods to analyze the Steinmetz system design . Several graphics evaluating the error introduced by assumption of balanced voltage in the design are plotted and an example is studied to compare both procedures . In the example the necessity to apply the optimization techniques in highly unbalanced conditions is demonstrated
