“…A special case is n = 6, where ( 8) is only applicable when the load has asymmetric windings with a single neutral point [60]. Alternatively, multiple ZSIs can be applied to achieve a 15.4% dc-link voltage utilization, similar to SVPWM, when n is a multiple of three and the neutral points are isolated [61]. For example, six-phase VSI with dual ZSIs was demonstrated in [62].…”

Multiphase Traction Inverters: State-of-the-Art Review and Future Trends

et al. 2022

View full text Add to dashboard Cite

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.
