In this paper several fault tolerant strategies which can be implemented on nine switch inverter has been investigated. The developed strategies provide compensation for open circuit and short circuit failures on semiconductor devices. In addition unique post fault controls have been proposed for each strategy. The first applied topology is switch redundant topology and can tolerate all switch failures. The second one is a four leg topology which tolerates just open circuit fault. The third one called phase redundant topology can deliver rated power at all switch failures. Finally performance of all post fault topologies is verified by simulation results.
