摘要
This paper presents a permanent magnet assisted synchronous reluctance motor driven light electric vehicle integrated with solar photovoltaic(SPV) panels and battery storage. The proposed system leverages regenerative braking and energy harvesting from rooftop mounted SPV to extend the driving range, contributing significantly to green mobility. A bidirectional DC-DC converter(BDDC) is employed to facilitate energy flow between the battery and the motor drive in either direction. During regenerative braking, the kinetic energy of the PMa-SyRM drive-based vehicle is converted into electrical energy. This recovered energy is injected into the battery, effectively charging the battery. This process not only extends the driving range of the vehicle but also minimizes energy loss, thereby enhancing overall efficiency. The conditional integrator-based anti-wind-up technique is employed for the speed control of LEV, which eliminates the problem of ringing and overshooting during the speed transitions. For better torque control of the PMaSyRM, maximum torque per ampere(MTPA) technique is used. Based on the torque command, MTPA technique produces set of current commands to minimize the magnitude of current vector. Constant voltage, current and torque curve study of the PMaSyRM assures that current and voltage of the drive remains in the safe limit.
