It has been mentioned in the literature that, among the multilevel inverter topologies used for STATCOM applications, the cascaded multilevel topology is the most advantageous and economical one. On the other hand, the main problem of this topology comes out to be the difficulty of sustaining the DC capacitors' mean voltages. This issue is very important for obtaining an output voltage with low THD and having equal device stresses. In this work, a new DC voltage balancing method (Selective-Swapping Algorithm) for cascaded multilevel inverter based STATCOM applications is investigated and the results are given. Moreover, these results are compared with the ones obtained for the other DC voltage equalization methods given in the literature.

Design and Implementation of a 154-kV +/- 50-Mvar Transmission STATCOM Based on 21-Level Cascaded Multilevel Converter Gultekin, Burhan; Gercek, Cem Ozgur; Atalik, Tevhid; Deniz, Mustafa; Bicer, Nazan; Ermiş, Muammer; Kose, Kemal Nadir; Ermis, Cezmi; Koc, Erkan; Cadirci, Isik; Acik, Adnan; Akkaya, Yener; Toygar, Hikmet; Bideci, Semih (2012-05-01) In this research work, the design and implementation of a 154-kV +/- 50-Mvar transmission static synchronous compensator (T-STATCOM) have been carried out primarily for the purposes of reactive power compensation and terminal voltage regulation and secondarily for power system stability. The implemented T-STATCOM consists of five 10.5-kV +/- 12-Mvar cascaded multilevel converter (CMC) modules operating in parallel. The power stage of each CMC is composed of five series-connected H-bridges (HBs) in each phas...
A Near State PWM Method With Reduced Switching Frequency And Reduced Common Mode Voltage For Three-Phase Voltage Source Inverters Un, Emre; Hava, Ahmet Masum (2007-05-05) The Near State PWM (NSPWM) method, which reduces the common mode voltage/current, is proposed for three-phase PWM inverter drives. The optimal voltage vectors and their sequences are determined. The voltage linearity and DC bus and AC output PWM current ripple characteristics are studied. The method is thoroughly investigated and its performance is compared to conventional methods. Theory, simulations, and experiments show that NSPWM exhibits superior common mode and satisfactory PWM ripple performance char...
Comparison of Inverter Topologies Suited for Integrated Modular Motor Drive Applications Ugur, Mesut; Sarac, Hakan; Keysan, Ozan (2018-08-30) In this paper, various inverter topologies are compared for integrated modular motor drive (IMMD) applications. Two-level voltage source inverter (2L-VSI), three level voltage source inverter (3L-VSI) and series/parallel combinations of these topologies with system level modularity are compared in terms of voltage and current harmonic spectrum, passive component sizes and motor drive efficiency. New generation wide band-gap GaN power semiconductor devices are utilized in modular topologies and they are comp...
A Near-State PWM Method With Reduced Switching Losses and Reduced Common-Mode Voltage for Three-Phase Voltage Source Inverters Uen, Emre; Hava, Ahmet Masum (2009-03-01) The near-state pulsewidth modulation (NSPWM) method, which reduces the common-mode voltage/current, is proposed for three-phase pulsewidth modulation (PWM) inverter drives. The method is described, its optimal voltage vectors are found, and the sequence that these vectors are applied is determined. Its voltage linearity and de bus and ac output PWM current ripple characteristics are studied. Its output line-to-line voltage pattern is carefully studied with regard to switching transients that may cause overv...
A Comparative Study of Surface Integral Equations for Accurate and Efficient Analysis of Plasmonic Structures Karaosmanoglu, Bariscan; Yilmaz, Akif; Ergül, Özgür Salih (2017-06-01) Surface integral equations, which are commonly used in electromagnetic simulations, have recently been applied to various plasmonic problems, while there is still no complete agreement on which formulations provide accurate and efficient solutions. In this paper, we present the strong material dependences of the conventional formulations, revealing their contradictory performances for different problems. We further explain the numerical problems in the constructed matrix equations, shedding light on the des...
