摘要
A node energy diagnosis method for a fault of a switched reluctance motor double-switch power converter. By detecting a transient value of a phase current of a switched reluctance motor double-switch power converter, a node energy standard deviation σ is calculated to be used as a fault characteristic quantity, and a main switch lower-tube short-circuit fault of the switched reluctance motor double-switch power converter is diagnosed by adopting a node energy standard deviation σ curve of the phase current of the switched reluctance motor double-switch power converter in the whole rotation speed range. It also can be applied in fault diagnosis when a main switch lower-tube short-circuit fault occurs in two phases or more than two phases of a switched reluctance motor double-switch power converter. It is applicable to switched reluctance motor power converters with various phase numbers and a double-switch structure, is durable, reliable in fault diagnosis and good in effect, and has good practicability, and wide application prospect.
