开绕组电机双逆变器拓扑分析与容错算法研究

摘要

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.%基于开绕组电机的双逆变器拓扑能够有效提高输出电压等级与输出电平数，利用MATLAB环境下的线性变压器、受控电流源等模块搭建了开绕组电机的电气流仿真模型。分析了双逆变器拓扑的数学模型，针对其容错特性，提出一种基于参考电压矢量解耦的SVPWM容错控制算法，并搭建实验平台进行验证。仿真结果以及实验结果验证了开绕组异步电动机仿真模型以及容错控制算法的有效性。
