Resumo(s)
This paper addresses the fault detection and
diagnosis of a fault in the switches of the Switched Reluctance
Machine (SRM) power electronic converter. Due to the
advantages of using multilevel converters with these
machines, a fault detection and diagnosis algorithm is
proposed for this converter. The topology under consideration
is the asymmetric Neutral Point Clamped (ANPC), and the
algorithm was developed to detect open and short circuit
faults. The proposed algorithm is based on an approach that
discriminates eccentricity of the images formed by the
converter voltages. This discrimination is realized through the
development of normalized indexes based on the entropy
theory. Besides the different fault type the algorithm is also
able to detect the transistor under fault. The possibility to
implement the proposed approach will be verified through
simulation tests.
