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...
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...
