摘要

The transition to electric vehicles (EVs) is crucial for promoting environmental sustainability and reducing greenhouse gas emissions. However, the efficiency and performance of EVs are often constrained by existing power conversion and control technologies. This research presents an advanced energy management system that combines a permanent magnet synchronous motor (PMSM) with a photovoltaic (PV) system to enhance EV efficiency. A novel high-gain interleaved SEPIC-Cuk converter is designed to boost the PV-generated voltage efficiently, ensuring a stable power supply to the PMSM motor. To maximize solar energy utilization, a modified Satin Bowerbird Optimization-Support Vector Machine Maximum Power Point Tracking algorithm is introduced, which dynamically adjusts to varying environmental conditions for optimal power extraction. Moreover, Proportional Integral control, Space Vector Pulse Width Modulation, and Direct Torque Control are employed to enhance motor speed and torque management, ensuring precise and efficient operation. Furthermore, a bidirectional single-phase DC link enables seamless energy exchange between the vehicle and external power sources, improving overall system flexibility. The proposed system is implemented in MATLAB Simscape Electrical, and the results demonstrate 92% converter efficiency, outperforming conventional techniques. The results indicate important developments in EV technology by enhancing system performance, power stability, and energy economy.
