In this paper, the conventional space vector modulation (SVM) and the unipolar carrier-based space vector pulse width modulation (CB-SVPWM) for three-level neutral-point-clamped (NPC) inverters are analyzed based on the continuous scheme. Essentially, the switching commutations of dual methods are obviously investigated and compared for all the operating of conditions along with their corresponding...
In this paper, a methodology to apply space vector modulation (SVM) to a three-level neutral point clamped (NPC) inverter based on volt-second balancing principle is presented. The proposed scheme, switching-state selection of the three-level NPC inverter by using a nearest three vector scheme, is fully described. A mathematical analysis of the duty cycle is determined by utilizing the calculated...
