Abstract
The rapid spread of light electric vehicles (LEV) increases the need for highly efficient and reliable motor drives. The main goal of this study is to design a unique BLDC motor driver hardware that can produce 3.5 kW continuous power at 72 V rated voltage, tolerant to large battery voltage fluctuations (50 V 84V) and high safety standards. For this purpose, a multi-layered power and control system has been developed based on a highperformance 32-bit microcontroller and intelligent gate driver architecture. Thermal losses were minimized by choosing power MOSFETs with ultra-low transmission resistance on the power floor, and the CAN Bus communication infrastructure was included in the design for the uninterrupted in-vehicle integration of the system. This hardware architecture provides an electrically and thermally secure, scalable prototype infrastructure for highpower density e-mobility systems prior to physical production.
