“…The cascaded H-bridge (CHB) inverter shown in Fig. 6, is one of the popular converter topologies used in highpower medium-voltage motor drives to achieve mediumvoltage with low harmonic distortion [46]. The wide adoption of Cascaded Multilevel Converters (CMC) and Modular Multilevel Converter (MMC) in the high-voltage direct current (HVDC) industry is mainly due to their modularity, scalability, and inherent fault tolerance [47][48][49].…”

“…When the duty reference is 0.86, the maximum magnitude of the neutral voltage reference with (32) decreases from 135.8V to 124.1V. This can also reduce the harmful effect of the large neutral voltage on the motor components such as bearings [23].…”

“…To compensate this disadvantage, the improved neutral-shift methods were proposed in [20][21][22]. In addition, there are attempts to combine the neutral point shift method with selective harmonic elimination based pulse width modulation [23]. However, these methods require either lookup tables or complex calculations for solving nonlinear equations.…”
