Three-phase current source inverter (CSI)-based induction motor (IM) drives are attractive in MV applications since they feature a simple inverter structure, a lower switching dv/dt, and a reliable short circuit protection. Although multiphase machine topic, especially the five-phase one, gains considerable interest recently in literature, almost all the applied control methods are targeting voltage...
Applications such as multiphase machine drives and wind energy conversion systems are normally based on voltage source converters (VSCs) which feature a convenient and familiar control scheme. In high-power medium voltage drives, three-phase current source converters (CSCs) are widely used owing to its simple topology, motor-friendly waveforms, power reversal capability, and short-circuit-inherited...
Multiphase machines have become challenging candidates for safety-critical applications that require wide fault tolerant capabilities and higher system reliability. However, this adds more complexity to the adopted power converters. In applications such as electrical submersible pump (ESP) systems, motor electric power is commonly fed using a three-phase low voltage variable frequency drive system...
Multiphase Machines offer a promising solution to many practical challenges due to their advantages over the three phase counterparts, as fault-tolerant capability and lower torque ripple magnitude. Among different multiphase machines, five-phase machines correspond to a relatively practical selection in industrial applications. Multiphase machines are conventionally fed from voltage source inverter...
Multiphase machines have become serious contenders for safety-critical applications that require wide fault tolerant capabilities and higher system reliability. However, this adds more complexity to the adopted power converters. Alternatively, passive transformation is a viable solution to obtain an n-phase supply from the three-phase grid. This paper investigates the existing connections of passive...
Wind energy is one of the fastest growing renewable energy sources. The increased penetration of wind power into the utility grid brings challenges such as voltage and frequency fluctuations, generator torque ripples, and grid faults to power converter design in wind energy conversion systems (WECSs). Multiphase PM generators offers a promising solution to many challenges due to their inherited advantages...
An electrical submersible pump (ESP) motor is preferably fed from a low voltage variable-frequency drive (VFD) followed by a step-up transformer. The motor and drive connection through a long feeder usually causes over voltage problems due to the travelling wave phenomenon, hence, filter networks on motor or inverter terminals are mandatory. The so-called boost-inverter intrinsically solves this problem...
