MMC based SRM Drives for Hybrid EV with Decentralized BESS

Owing to the growing demand for pollution free energy in metropolitan transport, HEV's (Hybrid electric vehicles) and EVs (Electric Vehicle) are gaining ample consideration due to their fuel efficient performance and no ecological damage due to the absence of harmful emissions. Thus countries all over the world are now paying increasing attention on the development of FV and HEV technology. HEVs (Hybrid Electric Vehicles) driven by SRM (switched reluctance motor) is supported by MMC (modular multilevel converter) has been proved to be a capable system by considering a hybrid vehicle system with decentralized battery energy storage system (BES S). 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 by offering several advantages. The functioning of the drive is effectively simulated in MATLAB and the performance is evaluated in the Generator Control Unit (GCU) with only driving case and GCU-Battery hybrid case. The battery cells are also investigated for analyzing fault tolerant ability in battery driving mode and GCU-battery hybrid mode.
