Abstract: This paper presents four different sequential switching hybrid-modulation strategies cascaded multilevel inverters. Hybrid-modulation strategies represent combinationsof fundamental-frequency modulation and multilevelsinusoidal-modulation (MSPWM) strategies, and are designed forperformance of the well-known alternative phase opposition disposition, phase-shifted carrier, carrier-based space-vector modulation, and single-carrier sinusoidal-modulations. The main characteristicof thesemodulations are the reduction of switching losseswith good harmonic performance, balanced power loss dissipationamong the devices with in a cell, and among the series-connected cells. The proposed modulations can be easily extended to three phase, and higher level inverters, operates with same physical structure of the power module. The feasibility of these hybrid modulations are verified through simulation, and experimental results.

Keywords: Cascaded multilevel inverter (CMLI), hybridmodulation.
