An analytical closed-form solution of ac current responses of a multilevel converter connected to the unbalanced grid in steady state is proposed in the contribution. The method of the solution can be used for different grid filter topologies and for unsymmetrical grid voltages and/or currents to analyze easily converter current responses in steady states. Thus, a quick comparison of converters with different number of voltage levels, control strategies, switching frequencies, power flows, and grid filter parameters may be performed to optimize their performance criteria.
