MMC-Based SRM Drives for Hybrid-EV with Decentralized BESS in Battery Driving Mode

Owing to the growing demand of pollution free energy in metropolitan transport, HEVs (Hybrid electric vehicles) and EVs (Electric Vehicle) have gained ample consideration due to their fuel efficient performance and no ecological damage as there are no harmful emissions. Thus countries all over the world are now paying attention for the development of EV and HEV technology. HEVs (Hybrid Electric Vehicles) driven by SRM (switched reluctance motor) supported by MMC (modular multilevel converter) proves to be a capable system when enhanced by decentralized battery energy storage system (BESS) in hybrid vehicle mobility. In this drive, a SM (sub-module) is comprised of cell of battery and half-bridge converter and numerous such Sub-modules together form MMC. Adjustable discharging and charging functionality for every sub-module are acquired by scheming SMs switches. This topology is unmatched to the conventional SRM drives and is also very beneficial as it offers several advantages. The functioning of the drive is effectively simulated in MATLAB and performance is evaluated. In this research work, modular multilevel converter based SRM drive is analyzed in the battery driving mode considering various cases.
