Space vector modulation for three-level simplified neutral point clamped (3L-SNPC) inverter

Abstract

In this paper, a Space Vector Modulation for the Three-Level Simplified Neutral Point Clamped (3L-SNPC) inverter is introduced. Models for the DC link dynamics and the 3L-SNPC inverter topology are developed. Different switching sequences are analyzed and compared. The neutral point balancing capability of the inverter is compared with conventional 3L-NPC inverter topologies. Simulation and experimental results prove the performance of the concept.
