Power inverter is an important device in nowadays technologies since the usage of renewable energy sources had been increased rapidly throughout world. The main focus research power field today to produce a high efficiency maximize obtained from i.e. reduce losses. In DC AC conversion, selection appropriate switching scheme be implemented very crucial. this paper, two different schemes, namely ...

– One promising technology to interface battery packs in electric and hybrid electric vehicles are multilevel converters. In the work presented here, it is shown how the switching times (angles) in a multilevel inverter can be chosen to achieve a required fundamental voltage and not generate speciÞc higher order harmonics. The method gives a complete solution to the problem in that all possible...

High-power current source inverters (CSI) usually operate at a low switching frequency to reduce loss. To suppress low-order harmonics and simplify filter design, the selective harmonic elimination pulse width modulation (SHEPWM) technique is feasible common strategy in industrial applications. This paper proposes an operational that uses H7 inverter (H7-CSI) with hybrid switches perform SHEPWM...

Multilevel inverter (MLI) topologies play a crucial role in the dc-ac power conversion due to their high-quality performance and efficiency. This article aims propose new switched-capacitor-based boost multilevel topology (SCMLI). The proposed consists of nine semiconductor switches with one dc voltage source two capacitors, capable generating nine-level output waveform twice gain. With additio...

Harmonic Elimination Strategy (HES) has been a widely researched alternative to traditional PWM techniques. This paper presents the harmonic elimination strategy of a Uniform Step Asymmetrical Multilevel Inverter (USAMI) using Particle Swarm Optimization (PSO) which eliminates specified higher order harmonics while maintaining the required fundamental voltage. This method can be applied to USAM...

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...
