摘　　要：针对基于整流桥交流供电的小惯量开关磁电机驱动系统,为了避免开关磁阻电机再生制动运行时能量回馈对母线器件的冲击,本文采用了一种开关磁阻电机绕组能耗制动方法,将制动产生的能量消耗在电机定子绕组上,通过对开关磁阻电机绕组能耗制动深入分析和仿真计算,提出了一种开关磁阻电机绕组两相直通绕组能耗制动控制方法,无需专门制动电阻泄放回路,在保证安全快速制动的前提下,简化了驱动系统的结构。以一台基于整流桥供电的四相8/6开关磁阻电机为应用对象,阐述所提方法的具体实施办法。研究结果表明该方法既可以产生必要的制动转矩,又可以避免制动能量回馈对母线电子元器件的冲击,提高了制动过程的可靠性和安全性。For the small inertia switched reluctance motor drive system based on the AC power supply of the rectifier bridge,in order to avoid the impact of energy feedback on the bus components during the regenerative braking operation of the switched reluctance motor,this paper proposed a new winding dynamic braking scheme.Through in-depth analysis and simulation calculation of the energy consumption braking of the SR motor windings,a new two-phase through winding energy consumption braking control scheme of the switched reluctance motor windings was proposed.There is no need for a special braking resistor bleeder circuit,and the structure of the drive system was simplified on the premise of ensuring safe and fast braking.Taking a four-phase 8/6 switched reluctance motor powered by a rectifier bridge as the application object,the specific implementation method of the proposed method was described.The research results show that the method can not only generate the necessary braking torque,but also avoid the impact of braking energy feedback on the electronic components of the bus,and improve the reliability and safety of the braking process.
