Abstract
A mathematical model based on space-vector theory is used to analyze inverter-fed induction motors faults. Inverter supply faults like an open phase fault, the failure of a transistor to switch on, the delay in a branch command, or the stand of the branch command are analyzed. These events introduce an asymmetry in the supply voltages, in the current values, and in the spatial field distribution. A detailed investigation of typical inverter supply failures is presented and discussed in order to identify remedial strategies.Keywords
