A five-phase induction machine model using multiple DQ planes considering the effect of magnetic saturation
Abdel-khalik, A. S.; Ahmed, Shehab; Massoud, Ahmed ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)Multiphase phase induction machines are usually modeled using multiple dq planes, where complete decoupling between these sequence planes is usually assumed. This assumption may be accepted if the magnetic circuit is assumed ... -
Exploitation of additional degrees of freedom of multiphase drives in low-frequency operation of modular multilevel converters
Daoud M.; Elserougi A.; Abdel-Khalik A.; Massoud A.; Bojoi R.; Ahmed S.... more authors ... less authors ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)MMC encounters serious limitations in the zero and low-frequency operation of variable-speed motor drives. In MMC, the voltage ripples of SubModule (SM) capacitor is inversely proportional to the phase current frequency. ... -
Sensorless field oriented control of five-phase induction machine under open-circuit phase faults
Morsy, A.S.; Abdel-Khalik, A.S.; Ahmed, S.; Massoud, Ahmed ( IEEE , 2013 , Conference Paper)Recently, multiphase machine is promoted to replace three-phase drives in high power safety-critical applications. Among the numerous advantages of multiphase induction machine drives, operation and self-starting under ... -
Sensorless V/f control with MRAS speed estimator for a five-phase induction machine under open-circuit phase faults
Morsy, A.S.; Abdel-Khalik, A.S.; Ahmed, S.; Massoud, Ahmed ( IEEE , 2013 , Conference Paper)This paper introduces a sensorless scalar controller with MRAS speed estimator based on simple Proportional Resonant PR controllers to provide a disturbance-free operation to a five-phase induction machine under phase open ...
