“…The rapid development of multilevel converters for drive systems has strongly improved DTC performance with regards to the torque ripple especially when a high number of levels are used [66]. Applying the DTC for converters with more levels, a larger number of voltage vectors can be exploited in order to better control stator flux and torque in induction motors.…”

The rapid growth of the electric vehicle market has stimulated the attention of power electronics and electric machine experts in order to find increasingly efficient solutions to the demands of this application. The constraints of space, weight, reliability, performance, and autonomy for the power train of the electric vehicle (EV) have increased the attention of scientific research in order to find more and more appropriate technological solutions. In this chapter, it proposes a focus on the main subsystems that make a zero-emission vehicle (ZEV), examining current features and topological configurations proposed in the literature. This analysis is preliminary to the various electric vehicle architectures proposed in the final paragraph. In particular, the electric drive represents the core of the electric vehicle propulsion. It is realized by different subsystems that have a single mission: ensure the requested power/energy based on the operating condition. Particular attention will be devoted to power subsystems, which are the fundamental elements to improving the performance of the ZEV.

“…In recent times, multilevel inverters (MLIs), specially cascaded Hbridge (CHB) inverters have been drawing remarkable interest and offering fascinating performance predominantly in medium-voltage high-power motor drive based traction and electric vehicle applications [1][2][3][4]. In the literature, several modulation schemes are discussed that improve the performance and efficiency of the MLIs.…”

An improved selective harmonic elimination-pulse width modulation (SHE-PWM) scheme has been proposed for a three-phase seven-level cascaded H-bridge (CHB) inverter that enhances the power utilisation capability of the inverter by sharing the desired amount of power among the H-bridge cells and also eliminates both 5th-and 7th-order harmonic components from the inverter output voltage maintaining the desired fundamental voltage component for a wide range of modulation index. Compared to conventional SHE-PWM, this scheme introduces two additional switching in the first cell, while the second and the third cells are switched at advanced switching angles. The differential search algorithm (DSA) technique has been applied to solve the proposed SHE-PWM scheme, and it exhibited comparatively better performance than the algorithm based on genetic algorithm, BEE algorithm and particle swarm optimisation. The effectiveness of the proposed scheme has been verified by both simulation and experimental study on a seven-level CHB inverter. Finally, the proposed scheme has been applied to the closed-loop constant V/f control of the induction motor drive application. It has been established that the proposed scheme is independent of the load power factor angle, and it improved the power conversion efficiency of the conventional SHE-PWM scheme. * reference rotor speed, rpm N r actual rotor speed, rpm T e electromagnetic torque, N-m V ab output line voltage, V i a , i b , i c output phase currents, A IET Power Electron.

“…In [28], a variable structure DTC scheme is introduced to reduce flux and torque ripples, but this method is motor parameter dependent and requires gain scheduling. A multilevel inverter is used to lessen the torque and flux ripples in [29][30][31]. However, a multilevel inverter increases the number of power switches, which increases the system cost and eventually the complexity of the drive train.…”

The governments worldwide have initiated programmes for faster adoption of electric vehicles (EVs) to meet the targets of the Paris Climate Change Agreement. One of the major challenges in meeting the targets of EVs' programmes is to develop cost effective and different types of EV drivetrains in a short span of time. One possible way to reduce the development time is to adapt systems and techniques, existing in industry applications, for EV application. Since, EV motor has to operate over a wide speed and torque range, it is necessary to ensure that the controller should have a good dynamic response over the entire operating range. An induction motor-based drivetrain with direct torque control (DTC) is chosen in this work. The DTC suffers from high torque ripple, and it will have an impact on rideability and comfort. To improve the performance of the DTC algorithm, a multi-band error status selection (ESS) method for the torque hysteresis controller is proposed and compared the existing ESS method. The proposed modification in the DTC architecture is tested on an experimental test bed for standard drive cycles used for validation of vehicles. The experimental results show that drive performance is enhanced using the proposed methodology.
