Abstract
In this paper, two different space-vector modulation (SVM) methods based on different basic voltage vectors of eight-switch three-phase inverters (ESTPIs), which are the post-fault reconfigured topologies for the three-level neutral-point-clamped (3L-NPC) inverter with the open-circuit fault in a leg, are analyzed. Based on the pulse-width modulation regular sampling method, the equivalent carrier-based pulse-width modulation (CBPWM) methods of these two different SVM methods are derived, respectively. By comparing these two CBPWM methods, the relationship between the two different SVM methods of ESTPIs is revealed. On the basis of that, the comprehensive relationship between CBPWM methods and SWM methods of ESTPIs is also revealed. Experimental results have shown the validity of the theoretical analysis.
