摘要
磁悬浮列车采用VVVF逆变器控制异步感应直线电机进行牵引和较高速工况下的制动,对牵引逆变器控制系统要求较高的实时性和可靠性。介绍的控制系统设计方案采用CPLD执行逆变器连锁保护任务,降低了中央处理单元软件的负荷,提高了牵引逆变器控制系统的可靠性。
VVVF invertor is used to control linear induction motor in propulsing Maglev train, so its reliability is the key. A resolution based on hardware design with Complex Programmable Logic Device(CPLD) to reduce the software load is describred.
