“…Numerous VSD-based SVPWM techniques for MPIs are invested in the reduction of CMV, induced by the highfrequency modulated inverters. The CMV excites a commonmode current, which is detrimental for many applications including motor drives and PV systems [81], [82]. The excited common-mode current contributes to motor aging rate by causing a bearing damage, insulation breakdown and electromagnetic interference (EMI) [83].…”

Multiphase inverters (MPIs) continue to increase in popularity owing to their compelling features that include enhanced fault-tolerance capability, improved per-phase power handling, and reduced dc-bus capacitor sizing. This article presents a comprehensive review on MPIs and their application in transportation electrification. More specifically, voltage source inverter (VSI) and nine-switch inverter (NSI) are the two MPI topologies reviewed herein, due to their popularity and potential for employment as traction inverters. The state-of-the-art review covers modeling and control techniques, dc-capacitor sizing, modulation strategies, inverter losses, and cost. Promising future trends of MPIs in terms of topologies, switching devices and integrated design are also investigated.INDEX TERMS Automotive, dc-ac converters, electric vehicles, inverters, power electronics, pulse width modulated power converters, transportation electrification, vector control.

“…This bearing current leads to motor terminal overvoltages, electromagnetic interference, the reduced motor efficiency. More than that, vibration in the shaft occurs, which causes the failure of the bearing, and hence the overall drive system suffers from reliability issues [17][18][19][20][21]. The CMV produces motor shaft voltage which causes a current that flows mainly through the bearing.…”

The multiphase matrix converter outperforms the conventional three‐phase system with higher fault tolerance capability and higher power control competency. This paper discusses the direct control based on different possible switching combinations of a three‐phase to five‐phase matrix converter (MC). The proposed control topology significantly reduces the switching commutations in a switching cycle when compared with its counterpart. The control is based on the modified space vector pulse width modulation (SVPWM) strategy. The proposed space vector scheme intelligently selects the voltage vectors to get the desired output characteristics with the least possible switching transitions in a switching cycle. Three possible cases exist in controlling space vectors based on their magnitude, the number of active switching vectors, and their commutations. The results for three different cases of SVPWM have been presented and compared. The total harmonic distortion (THD) obtained in the output is lower in case 2; however, it suffers from a higher common‐mode voltage (CMV). The scheme has been successfully implemented and verified in hardware.

Multi-phase converters for more than three-phase applications have become increasingly important topics due to their distinct advantages compared with the conventional three-phase converters. This paper proposes a modified PWM switching technique for direct AC-AC three-to-five phase matrix converter to realize output voltage waveform with low total harmonic distortion (THD) and reduce the total commutation number of its bidirectional power switches in each control period, simultaneously. In order to minimize the switching loss and reduce the voltage stress on all power switches of the matrix converter, the proposed PWM switching pattern prevents any state of direct commutation and switching between the maximum and minimum grid phase voltages. This in-turn enhances the converter durability and lifetime in addition to the power density. Also, the proposed PWM switching technique has the ability to fully control the load voltage waveform and its frequency to meet the reference values. In addition, it has the ability to control the three-phase grid currents to be sinusoidal waveforms and in-phase with grid voltages for unity power factor. Moreover, it enables voltage transfer ratio of 78.86% of the source input voltage. A laboratory prototype has been carried out in order to investigate the effectiveness of the proposed switching technique.
