Thirteen and Fifteen Level Neutral Point Clamped Multilevel Inverter

Multilevel inverters (MLI) becomes more accepted over the last few years in high power application of electrical engineering with the advantage of less disturbances and the possibility to work at lower switching frequencies as compared to conventional two-level inverters. In this paper the simulation of single phase multilevel inverter is present. Simulation of three level, five level, seven le...

Direct Torque Control for Three-Level Neutral Point Clamped Inverter-Fed Induction Motor Drive

Direct torque control (DTC) is a control technique in AC drive systems to obtain high performance torque control. The classical DTC drive contains a pair of hysteresis comparators and suffers from variable switching frequency and high torque ripple. These problems can be solved by using space vector depending on the reference torque and flux. In this paper the space vector modulation technique ...

A Review on New Hybrid Active Neutral Point Clamped Flying Capacitor Multilevel Inverter

This paper presents the hybrid seven-level cascaded active neutral-point-clamped (ANPC)-based multilevel converter. The converter topology is the cascaded connection of a three-level ANPC converter and an H-bridge per phase. The proposed topology provides a tradeoff between different component counts to achieve a good loss distribution, avoid direct series connection of semiconductor devices, k...

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...
