Fault-Tolerant Multilevel Converter to Feed a Switched Reluctance Machine

The switched reluctance machine (SRM) is one of the most interesting machines, being adopted for many applications. However, this requires a power electronic converter that usually fragile element system. Thus, in order to ensure high reliability system, it fundamental design with fault-tolerant capability. In context, new solution proposed give capability This was designed purpose two types switch faults, namely open- and short-circuit. Moreover, apart from feature, topology characterized by multilevel operation allows improvement performance SRM, taking into consideration wide speed range. Although presented an 8/6 can be used other configurations. will described modes, normal operation. Another aspect addressed paper proposal fault detection diagnosis method inverter. It specifically developed SRM drive. theoretical assumptions verified through different tests, firstly simulation secondly experiments laboratory prototype.
