摘　　要：针对燃料电池汽车使用大功率DC-DC变换器带来的高成本与效率损失问题,提出了将双绕组永磁同步电机引入燃料电池汽车系统的设计思路,利用两套绕组间的互感关系替代DC-DC变换器。首先根据电磁感应原理以及双d-q建模的方法建立了双绕组永磁同步电机的数学模型,分析了在双d-q坐标系下两套绕组间的耦合关系及其对电机输出转矩的影响。其次在燃料电池汽车系统下,阐述了双绕组永磁同步电机驱动系统的用法,针对汽车处于停车状态时,采用q轴零电流d轴磁场交替变化的矢量控制方法,研究电机在保持零转矩转速状态下,从燃料电池经由双绕组电机到二次电池的能量传递问题。最后通过仿真分析和实验验证了模型及所提出的零转矩转速条件下绕组间能量交换方法的正确性。Aiming at the high cost and efficiency loss caused by the use of high-power DC-DC in fuel cell vehicles,the design of introducing dual-winding permanent magnet synchronous motor into fuel cell vehicle system is proposed,and it uses the mutual inductance between two sets of winding to replace the DCDC converter. Firstly,according to the principle of electromagnetic induction and the method of double d-q modeling,the mathematical model of the motor was established,and thereby,the coupling relationship between the two sets of winding under the dual d-q coordinate system and its influence on the torque of the motor were analyzed. Secondly,when the vehicle was in the parking state under fuel cell vehicle system,the motor should maintain torque and speed at zero. By the means of keeping the current on qaxis zero and changing the magnetic field on d-axis alternately,the problem that how to transfer energy from fuel cells to the secondary battery through the dual-stator motor is studied. Finally,the simulation and experimental results verify the correctness of the model and the energy exchange method between windings under the conditions that both torque and speed are zero.
