Four-switch three-phase inverters (FSTPIs) are post-fault reconfigured topologies for a two-level inverter with failure of power switch or leg, and space vector pulse-width modulation (SVPWM) strategies have been used to control FSTPIs. However, different faulty legs correspond FSTPIs which controlled by SVPWM strategies; therefore, three need be prepared FSTPIs, respectively, takes up lots memory in the controller increases complexity strategy. To overcome these disadvantages, general strategy that can is proposed. Experimental results shown validity feasibility proposed
