The paper presents a high performance flying capacitor fed induction motor drive. To improve the performance of Flying Capacitor Multilevel Inverter (FCMLI) implement the switching pattern selection scheme. This scheme reduces capacitor voltage fluctuation without using voltage feedback. This method is developed for sinusoidal voltage generation using the sinusoidal pulse width modulation techn...

Induction motor drive is used in almost all industries including oil and gas sectors, production plants and process industries. Speed control of induction motor is a major concern. The proposed technology implements a better speed control for induction motor drives using a multilevel inverter. The switching sequences are generated by optimized pre-calculated angles for controlling induction mot...

Nowadays, high-speed permanent magnet synchronous machines (HSPMSMs) are widely used in direct-drive applications. Moreover, modular multilevel converters (MMCs) have attracted a lot of attention. In this paper, the mathematical model MMC for HSPMSM was built on high- and low-speed regions, respectively, control each is completely decoupled. energy balance schemes based common mode current inje...

This Paper presents the Phase Disposition Scheme, which is topology independent. This scheme is used in Multilevel Inverters, interleaved parallel combination. Analysis on the other scheme which is Phase Opposition Disposition has also been performed. The best strategies related to the paralleling of inverters are evaluated, particularly those associated to current balancing between commutation...

There are problems in the limitations of conventional inverters, especially in high-voltage and high-power applications. Recently multilevel inverters are becoming increasingly popular for high-power applications due to their improved harmonic profile and increased power ratings. Several studies have been reported on multilevel inverters topologies, control techniques, and applications. However...

Several works have been reported in the literature on multilevel inverters topologies, control techniques and applications. However, there are few works that actually discuss or evaluate the performance of induction motor drives associated to three-phase multilevel inverter. This paper presents then a comparison study for a cascaded H-bridge multilevel DTC induction motor drive. In this case, s...

This paper presents a hybrid cascaded H-bridge multilevel motor drive Direct Torque Control (DTC) scheme for electric vehicles (EVs) or hybrid EVs. The control method is based on DTC operating principles. The stator voltage vector reference is computed from the stator flux and torque errors imposed by the flux and torque controllers. This voltage reference is then generated using a hybrid casca...
