In recent times, abbreviated switch calculates multilevel inverter (RSC-MLI) has become an regressing area of inquiry in power electronic converters. To ascendance these RSC-MLI topologies, different novel modulation connives are reported. Multi reference is one such changes scheme covered for different RSC topologies, such as T-type. Even so, the performance of this old scheme results in high total harmonic distortion (THD) in line voltages, when equated with the conventional level shifted pulse-width modulation planes. This observation is now in this study and the reason for its degraded THD performance has been intensely discussed. To appease this question, a modified multi-reference dual-carrier modulation technique with multiple references and two carriers is intended. To carry out this proposed modulation methods, an alternate carrier and modulation signals arrangement with various carriers and single reference is also awarded. Finally, a relative THD performance of the given and conventional modulation methods is carried out on a five-level T-type MLI and found simulation results are corroborated experimentally.
