【摘要】：汽车行业的迅猛发展,给人类的交通带来了极大的便利,但同时也使环境污染、全球变暖以及能源短缺问题变得日益突出,因此节能环保的新能源汽车尤其是电动汽车近些年来实现快速发展。电机驱动系统是电动汽车核心技术之一,驱动逆变器是影响电动汽车能效、安全性、可靠性的重要因素,论文对电动汽车用电机驱动逆变器展开了相关研究。论文第一章介绍了驱动逆变器的散热方式和应用SiC等新型功率器件的驱动逆变器研究现状,然后分析了永磁同步电机常见的控制策略,并对比了基于位置传感器获取电机转子位置方法的研究现状。论文第二章研究了电机驱动风冷逆变器散热系统的设计方法,通过建立逆变器和散热器的热阻模型,得到散热器热阻与其几何参数的关系,然后对散热器的几何参数进行设计,并分别采用热仿真和实验与理论设计进行比对。本文还对SiC MOSFET和Si IGBT实验平台的散热设计进行了比较。论文第三章基于永磁同步电机数学模型,针对磁场定向(i_d=0)矢量控制策略,完成硬件电路和软件系统的设计,其中主要分析了基于旋转变压器的转子位置检测电路的设计,并搭建了 10kW SiC MOSFET电机驱动逆变器实验平台,对转子位置检测电路和磁场定向(i_d=0)矢量控制进行实验验证。论文第四章对所做的研究工作进行总结,并对未来的工作进行展望。
[Abstract]:The rapid development of automobile industry brings great convenience to human transportation, but it also makes environmental pollution, global warming and energy shortage become increasingly prominent. Therefore, energy-saving and environmental-friendly new energy vehicles, especially electric vehicles, have achieved rapid development in recent years. Motor drive system is one of the core technologies of electric vehicle. Driving inverter is an important factor affecting energy efficiency, safety and reliability of electric vehicle. The first chapter introduces the heat dissipation mode of the drive inverter and the research status of the drive inverter using new power devices such as SiC, and then analyzes the common control strategies of the permanent magnet synchronous motor (PMSM). The research status of rotor position acquisition based on position sensor is compared. In the second chapter, the design method of the heat dissipation system of the air-cooled inverter driven by the motor is studied. By establishing the thermal resistance model of the inverter and the radiator, the relationship between the thermal resistance of the radiator and its geometric parameters is obtained, and then the geometric parameters of the radiator are designed. The thermal simulation and experiment are compared with the theoretical design. The heat dissipation design of SiC MOSFET and Si IGBT experimental platform is also compared in this paper. In the third chapter, based on the permanent magnet synchronous motor (PMSM) mathematical model, the design of the hardware circuit and the software system is completed, and the design of the rotor position detection circuit based on the rotary transformer is mainly analyzed. The experimental platform of 10kW SiC MOSFET motor drive inverter is built to verify the rotor position detection circuit and the field oriented control system. The fourth chapter summarizes the research work and looks forward to the future work.
