| Abstract: | Traction inverter with high-voltage ＆ large-current power devices and asynchronous traction motor has become the mainstream circuit structure of high-speed EMU traction system, and the vector control technology has been widely used as one of the high performance traction motor control strategies. From the practical point of view, this paper introduces several key technologies of EMU traction motor vector control system, including voltage and current measurement, voltage decoupling algorithm, rotor flux observer model, stator frequency correction and multi-mode PWM modulation. |
