Improvement of the switching system in the power distribution for three-phase to single-phase matrix converter system with neutral line

Using three-phase to single-phase Matrix Converters with neutral line (single-phase MCs) instead of transformers in consumer side on micro-grid is studied. In single-phase MC, input and output current had formulated in the literature [1]. However, I found that the phase shift of the input current which not present in the theoretical formula is occurring. In this paper to elucidate the cause of the phase shift, we intend to make the analysis of the harmonics generated by the switching. We analyzed the switching of single-phase MCs from a simulation result.
