The dual inverter-fed topology based on the open-end winding induction motor could effectively increase the output voltage and the output level. An electrical flow simulation model of the open-end winding induction motor was built by using the linear transformer and the controlled current source in the MATLAB/Simulink. The mathemati-cal model of the dual inverter-fed topology was analyzed. In view of the fault-tolerant performance,a SVPWM fault-tolerant control algorithm based on the reference voltage vector decoupling was proposed,and an experimental platform was constructed. The simulation results and experimental results verified the effectiveness of this simulation model and the fault-tolerant control algorithm.
