In this study, a novel topology for symmetrical voltage source multilevel inverter is proposed, which comprises series connection of basic unit cells with H-bridge. It offers same voltage level with lower number of power semiconductor switches as compared with traditional cascaded Hbridge and other recent topologies, thereby reducing the number of gate drivers which in turn reduce the installat...

A generalized formulation of Selective Harmonic Elimination (SHE) PWM for Multilevel Inverter is recently formulated in literature which can eliminate a large number of lower order harmonics. Various methods for calculating the firing angles for SHE PWM are known and still research in this area is ongoing. This paper presents a MATLAB based approach for modeling and simulation method suitable f...

This paper presents a comprehensive review on three basic types of multilevel inverters i.e., diode-clamped, flying-capacitor, and cascaded H-bridge multilevel inverter and their variation for photovoltaic power system. The electrical power generated form photovoltaic power system is in DC form. Hence, it is necessary to be controlled and converted to useful form. Inverter is a power electronic...

A modified sinusoidal pulse width modulation technique used to control switches inverter. The simulation result...

Multilevel converters have received serious attention on account of their capability high voltage operation, efficiency, and low electromagnetic interference. It has many advantages compared to conventional two-level inverters such as dc-link voltages, reduced harmonic distortion, fewer stresses, interferences. The multilevel been used for STATCOM widely it can improve the power rating compensa...

Power electronic converters, especially DC/AC Sinusoidal Pulse Width Modulation inverters have been extending their range of use in industry because of their numerous advantages. They typically synthesize the stair –case voltage waveform (from several dc sources) which has reduced harmonic content. This paper describes the development of design, modelling and simulation of the proposed seven le...

A New Static Var Generator (SVG), using cascaded full-bridge inverters (FBI) with binary output levels and the parallel connections of two cascaded inverters by means of current sharing reactor in each phases is introduced. The new M-level inverter, where M is 2n+2 - 3, consists of only 2n single-phase full bridges for each phases. The proposed technique not only increases the current capacity ...
