         Space-Vector PWM Technique for Five-Phase Open-End Winding PMSM Drive Operating in the Overmodulation Region  
 
Author   Priestley,Matthew (Author)
Fletcher ,John Edward (Author)
Journal Title   IEEE Transactions on Industrial Electronics
Volume/ Issue   2018/SEP V.65 N.9
Physical Description   p 6816 - 6827
Subject Area   Engineering
Abstract   The five-phase open-end winding inverter topology has a low-impedance zero-sequence current path when a single dc supply is used. As a result of this, any source of common-mode voltage in the circuit can lead to an uncontrolled low-frequency zero-sequence current. This is an issue for permanent magnet machine systems as they can possess zero-sequence components in the back electromotive force, which will couple with the generated zero-sequence current to produce undesired torque pulsations.... | View Full Abstract

         FOC Transformation for Single Open-Phase Faults in the Five-Phase Open-End Winding Topology  
 
Author   Priestley,Matthew (Author)
Journal Title   IEEE Transactions on Industrial Electronics
Volume/ Issue   2020/FEB V.67 N.2
Physical Description   p 842 - 851
Subject Area   Engineering
Abstract   Many critical five-phase permanent-magnet synchronous machine drive systems require operation after a single open-phase fault. The single dc supply open-end winding inverter topology allows for the injection of four unbalanced phase currents to better optimize the postfault machine torque after this fault. However, all previously published field-oriented control schemes send varying current references to the proportional-integral (PI) current controllers when controlling four unbalanced phase currents. This makes the design of the PI controllers considerably difficult as each machine operating point will require a different gain to accurately track the varying reference with minimum ripple.... | View Full Abstract
