This thesis presents a novel cascaded multiport switching reluctance motor (SRM) drive designed for hybrid electric vehicles (HEVs) in this master thesis. The capacity of this technique to adeptly handle energy conversion between the generator/ac grid, battery reserves, and the motor is what makes it special. Aside from that, it provides a strong battery management (BM) system that successfully monitors SOC balance and orchestrates bus voltage regulation. A critical component of our design is the seamless integration of the battery packs and the AHB converter. This not only makes it easier to create cascaded BM modules, but it also prepares the stage for SRM drive-specific multilevel bus voltage and current capacity adjustments. This configuration improves the excitation and demagnetization phases of commutation, broadens the speed spectrum, reduces voltage stresses on switching components, and improves torque capability and overall efficiency. Here tailored the system to meet a variety of operational demands by including alternative driving patterns, regenerative braking systems, and charging techniques into the proposed converter. Our BM strategy's ability to manually link or unlink each battery pack from the power supply is an exciting feature. This one-of-a-kind feature considerably improves the system's fault-tolerance and easily avoids any overcharging or over draining problems during motor activity. Empirical experiments using a three-phase 12/8 SRM confirmed the feasibility and efficacy of our proposed cascaded multiport SRM drive.
