Discontinuous Space Vector Modulation Strategy for Three-Level Neutral Point Clamped Inverter

Abstract:

This paper presents a discontinuous space vector modulation (SVM) strategy for a three-level neutral point clamped (3L-NPC) inverter. The proposed scheme, calculation switching time of the 3L-NPC inverter is fully described. A mathematical analysis of the duty cycle is determined by utilizing the calculated switching time method. The main advantages of the proposed method are minimization of the number of commutations of switches and reduction of the switching losses. Simulated and calculation results are presented to verify the validity and effectiveness of the proposed modulation scheme.
