An Impedance Network-Based Three Level Quasi Neutral Point Clamped Inverter with High Voltage Gain

A Study of Three-Level Neutral Point Clamped Inverter Topology

The three-level Neutral Point Clamped (NPC) inverter has become matured and widely used topology in high-power medium-voltage applications due to several advantages associated with it as compared to other available multilevel topologies. This paper presents a brief review on operation of threelevel NPC inverter. Different modulation strategies used in NPC inverter is also discussed. The problem...

Implementation and Comparison between Two Algorithms of Three-Level Neutral Point Clamped Voltage Source Inverter

This paper presents a comparison between two Pulse Width Modulation (PWM) algorithms applied to a three-level Neutral Point Clamped (NPC) Voltage Source Inverter (VSI). The first algorithm applied is the triangular-sinusoidal strategy; the second is the Space Vector Pulse Width Modulation (SVPWM) strategy. In the first part, we present a topology of three-level NCP VSI. After that, we develop t...

Space Vecor Modulated Three Level Neutral Point Clamped Inverter Using A Single Z Source Network

The Neutral Point Clamped (NPC) three-level inverter with Z-source network is a relatively recent converter topology that exhibits both voltage-buck and voltage-boost capability. This concept can be applied to all acto-ac, dc-to-dc, ac-to-dc, and dc-to-ac power conversion whether two-level or multilevel. However, multilevel inverters offer many benefits for higher power applications. Existing p...
