中文摘要：

主要研究了基于图形用户界面（GUI）的逆变电路故障仿真.在Matlab/Simulink环境下,通过建立具有不同故障模式的逆变器驱动系统,再进行GUI封装,最后形成一个基于GUI的逆变器驱动系统故障仿真平台.利用这个平台可任意调用处于不同故障模式下的逆变器模块,并且可获得它们输出相电流和转矩的波形.结果表明,输出相电流和转矩可以作为故障特征实现逆变器的快速故障检测与诊断.

英文摘要：

The simulation for inverter circuit under fault conditions based on Graphical User Interface（GUI） is studied primarily in this paper.Different blocks under different power device fault conditions are built by the basic blocks of Matlab/Simulink toolboxes.And then using the GUI to encapsulate these blocks,the simulation platform for inverter drive system under fault condition is formed.Every block can be called freely and the waveforms of the phase current and torque are plotted simultaneous by the GUI platform.By studying these waveforms,the result shows that the phase current and torque can be used as fault characteristics to achieve inverter fault detection and diagnosis rapidly.
