The Effect Fault of Inverter Multi Levels on Asynchronous Machine

The voltage source inverter has a diversity known in many industrial applications, such as the variation speed in electrical training. But the characteristic inverter recognized grace of the power electronic development can presented a structural faults, however the closed fault of semiconductors, that can provoke a serious problem for the protection of the system. This article presented the diagnostic of the inverters multi levels associates with the three-phase asynchronous squirrel-cage machines witch show the faults of the switches for each inverter multi levels and their influence on the answers of speed and torque.
