Abstract

The rapid development and expansion of the EV market marked by the advent of third decade of the 21st century has improved the possibility of a sustainable automotive future. The present EV drivetrain run by BLDC motor has become increasingly complicated thus requiring efficient and accurate controls. The paper begins with discussing the problems in existing models, the research then focuses on increasing the robustness of the system towards disturbances and uncertainties by using Sliding Mode Control to control the ZSI, which has been chosen as the main power converter topology in place of VSI or CSI. The introduction of SMC has improved the performance of the drivetrain when applied with Vehicle dynamics over a Drive Cycle.
