Reduced Switch Multilevel Inverter Topologies And Modulation Techniques For Renewable Energy Applications

Multilevel Inverters: Literature Survey – Topologies, Control Techniques & Applications of Renewable Energy Sources - Grid Integration

Multilevel inverters are in favor of academia as well as industry in the recent decade for high-power and medium-voltage applications. In addition, they can synthesize switched waveforms with lower levels of harmonic distortion compared to a two-level converter. Multilevel converters have received increased interest recently as a result of their ability to generate high quality output waveforms...

Comparison of Modulation Techniques for Cascaded and Reverse Voltage Multilevel Inverter Topologies

Multilevel inverters have been widely used for highpower, high-voltage applications. Among the existing multilevel inverter topologies Cascaded inverter topology has many advantages over Neutral point clamped and Flying capacitor inverters, but it requires isolated DC sources which is a main drawback of this topology. A new topology with a reversingvoltage component requires fewer numbers of co...

A Simplified PWM Technique for Reduced Switch Count Multilevel Inverter

Received Sep 19, 2017 Revised Dec 30, 2017 Accepted Jan 17, 2018 Penetration of multilevel inverters (MLI) in to high power and medium voltage application has been increasing because of its advantages. A conventional two level inverter has high harmonic distortion which gives poor power quality. Lot of topologies has been developed to overcome the drawbacks of two level inverter. These topologi...

Selective Harmonic Elimination with Reduced Switch Topology in Multilevel Inverter

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...
