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...

Real Time Simulation of SPWM And SVPWM Based Neutral Point Clamped Three Level Inverter

Abstract— Multilevel inverters have gained importance in medium voltage and high power drives applications due to superior performance over two level inverters such as lower harmonics, less voltage stress, better harmonic profile, reduced dv/dt stress, produce lower common mode voltage etc., This paper focuses on implementation of Space Vector Pulse Width Modulation (SVPWM) Technique for Three ...

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 ...
