Abstract :
Fault diagnosis for three-phase inverter was discussed in this paper. Firstly, the type of three-phase inverter driving system fault was reviewed, and then the system state equation model was constructed based on the open-circuit fault of power transistor base, thirdly, it was realized effectively through the residual generator method based on geometric space theory. Finally, the validity of proposed method was conformed by the simulation.
