Different faults in power semiconductors are considered, and the available postfault states of the converter are shown. In regard of the operation limits, two possible solutions are presented. In these solutions, adding a reduced number of additional components, the behavior of the converter when a switch fails improves considerably. Furthermore, an analysis of the neutral-point voltage balancing conditions after a fault and reconfiguration of the system is also evaluated. Experimental results that prove the correct operation of the proposed topologies are shown.10enginfo:eu-repo/semantics/restrictedAccessjournal article10.1109/TIE.2009.2026710Fault tolerancemultilevel converterneutral-point-clamped (NPC) converterreliabilityvoltage oscillationControl and Systems EngineeringElectrical and Electronic Engineeringhttp://www.scopus.com/inward/record.url?scp=77954615301&partnerID=8YFLogxK
