The proposed study reports the essential parameters required for the battery charging schemes deployed for Electric Vehicle (EV) applications. Due to efficient power delivery, cost-effectiveness, and environmental acclimation, EVs have emerged as a suitable alternative to the Internal Combustion (IC)-based engines. However, prominent challenges for leveraging the EVs are the suitable availability of battery charging infrastructure for high energy/power density battery packs and efficient charging topologies. Despite the challenges, EVs are gradually being implemented across the globe to avoid oil dependency, which currently has a 5%-7% decline rate of post-peak production. The vast deployment of EVs as private and commercial vehicles has created a major challenge for the grids in maintaining the power quality and peak load demand. This study, therefore, reviews the various battery charging schemes (battery charger) and their impact when used in EV and Hybrid EVapplications. The available constituents of the battery chargers such as ac-dc/dcdc converter topologies, modulations, and control techniques are illustrated in detail. The comprehensive study classifies the charging topologies depending upon the power and charging level. Some appropriate battery charging converter topologies that are suitable for domestic, industrial, and commercial applications like EVs are suggested in the study. In addition, a decision-making inference is developed through a flow chart that decides on the suitable selection of the converter topology based on the required applications. Furthermore, the charging infrastructures along with the converters' design standards are also discussed concisely, which adds a significant contribution to the review article.

The reduction of harmonic torque and ripples in low-switching VFI-based induction motor (IM) drives is a crucial consideration for improving efficiency, service life, drive damage, potential shaft failure for high power/speed drives and overall performance. In literature, existing solutions to these issues involve the implementation of standardized pulse width modulation (PWM) techniques such as sinusoid modulation technique PWM (SMT-PWM) and selective harmonic reduction PWM (SHR-PWM). However, this research proposes a P-PWM-based approach to address the reduction of harmonic magnitude and torque ripple in low-switching VFI-based IM drives. The proposed P-PWM-based approach is specifically applied for three and four-angle switching per quarter cycle (Aq), targeting the reduction of lower-order harmonic magnitude and torque ripples ranging from 6th to 6(Aq-1)th order. By relying on independent specifications and loading states, the P-PWM approach accommodates different Aq and higher-order harmonics. Extensive comparisons with SMT-PWM and SHR-PWM, supported by findings from a 1hp VFI-based IM drive using a TYPHOON-HIL-based hardware setup, demonstrate the superior performance of the P-PWM approach in terms of reducing the harmonic magnitude and torque ripples.
