摘　　要：介绍了１０００ｋＷ油冷变流器地面试验系统中逆变器实时控制器的硬件结构和软件功能。试验结果表明，采用该实时控制器较好地解决了电机平滑起动、软件合成频率、ＳＰＷＭ实时计算以及移缺口控制等技术问题。The hardware structure and software function of inverter real time controller are described for 1000 kW oil cooled converter in ground system test. The test results indicate that technical issues like smooth start up of motor, software synthesis frequency, SPWM real time arithmetic and notch displacement control can be satisfactorily handled with this real time controller. This device has been adopted on the newly developed AC4000 electric locomotive with AC drive.
