Abstract

The swift rise in electric vehicle (EV) usage requires the creation of efficient, compact, and reliable motor drive systems. Brushless DC motors are well-suited for EV propulsion due to their superior torque density, low maintenance, and precise controllability. However, optimizing their performance depends significantly on the design of power conversion interfaces. This study investigates a bridgeless Landsman converter (LSM-C) integrated with a VSI to drive a BLDC motor operating in discontinuous mode (DICM). The proposed architecture is evaluated under varying load and voltage conditions, and its dynamic behavior is analyzed using key time- domain performance metrics (i.e.,) Integral Error Criteria (IAE, ITAE and ISE). Simulation results confirm that the system maintains stable operation with minimal overshoot and voltage ripple, even under transient conditions. The findings highlight the potential of this configuration for enhancing the energy efficiency and responsiveness of EV drive systems, contributing toward low emission mobility and sustainable urban transport solutions.
