| Abstract: | Traction system is the core technology of EMU.Fault diagnosis of three-level motor inverter of vector control is very important.In this paper,taking the three-level inverter of CRH2 as the background,the Matlab/Simulink simulation model of vector control system of three-level space vector pulsewidth modulation(SVPWM) inverter is established,and simulation is carried out.The waveforms of the output voltage,current,torque and speed of three level inverter and their effects on the motor performance are analyzed under five common fault conditions which can provide technical reference for the fault diagnosis of three-level motor inverter of CRH2. |
