Simulation of 3D-space vector modulation for neutral point clamped inverters

Abstract

This paper gives an idea to simulation of three-dimensional space vector modulation for neutral point clamped multilevel inverter. Three dimensional-space vector modulation (3D-SVM) algorithm is progressed method of two dimensional-space vector modulation (2D-SVM) algorithm; it leads to reduce the complexity in reference vector identification and switching time calculation, also it includes the various advantages of 2D-SVM like minimized total harmonic distortion, reduced EMI issues. A simple system for the assortment of switching state vectors to track the reference voltage vectors without using any redundant switching vectors. This proposed method tracks the reference vector by identifyinglsubcubes and prisms by using mathematicallconditions. Here the cost of the proposedltechnique is independentlof voltagellevels oflinverter. This paper realizes the accomplishment of 3D-SVM using a neutral point clamped inverter. The simulation results of the proposed method are verified using MATLAB/Simulink.

A comprehensive review on different types of fuel cell and its applications

“…One approach is to improve the performance of the catalysts used in DMFCs, which can increase the rate of the methanol oxidation reaction and improve the efficiency of the cell. Another approach is to optimize the design of the fuel cell, such as the flow channels and the membrane electrode assembly, to improve the performance and reduce the costs of the cell [29].…”

Kel Kartal Arama Optimizasyon Algoritması Kullanarak Çok Seviyeli SHE-PWM İnverter İçin Optimum Anahtarlama Açıları Oluşturma

“…Bu sayede çıkış geriliminin basamaklı dalga formu nedeniyle ortama daha az harmonik sağlar. Bununla birlikte, bazı çalışmalar harmonik içeriğin azaltılmasını sağlayacak yüksek verimli teknikler sunulmuştur ve bu doğrultuda sinüzoidal SPWM, SHE-PWM ve uzay vektör modülasyonu (UVM) gibi farklı yaklaşımlar geliştirilmiştir [3][4][5]. Ancak, PWM yaklaşımlarıyla düşük dereceli/sıralı harmonikler tamamen ortadan kaldırılamaz.…”
