The underlying optimization problem aims at minimizing the output current ripple and is solved off-line, resulting in an optimization vector that defines the output DC current sharing and the phase lags between the 3 converters. The resulting technique demonstrates a significant reduction both in the DC current and DC voltage ripples.enconference paper
