Selective Harmonics Elimination Technique in Cascaded H-Bridge Multi-Level Inverters Using the Salp Swarm Optimization Algorithm

A new optimization method is proposed in this paper for finding the firing angles in multi-level voltage source inverters to eliminate low-order selective harmonics and reduce total harmonic distortion (THD) value of the output voltage. For thid end, Fourier series is used for calculating objective function and selecting specific harmonics. Regarding the nature and complexity of the employed no...

Harmonics Elimination in Multilevel Inverter Using Linear Fuzzy Regression

Multilevel inverters supplied from equal and constant dc sources almost don’t exist in practical applications. The variation of the dc sources affects the values of the switching angles required for each specific harmonic profile, as well as increases the difficulty of the harmonic elimination’s equations. This paper presents an extremely fast optimal solution of harmonic elimination of multile...

Harmonics Elimination in Cascaded Multilevel Inverter Using PWM Method

In this project, a multilevel inverter was designed and implemented to operate a stand-alone solar photovoltaic system. The proposed system uses selective harmonics elimination pulse-width modulation (PWM) in the multilevel inverter to convert DC voltage from battery storage to supply AC loads. In the PWM method, the effectiveness of eliminating low-order harmonics in the inverter output voltag...

Single-Phase Seven-Level Grid-Connected Inverter for Photovoltaic System

This paper proposes a single-phase seven-level inverter for grid-connected photovoltaic systems, with a novel pulsewidth-modulated (PWM) control scheme. Three reference signals that are identical to each other with an offset that is equivalent to the amplitude of the triangular carrier signal were used to generate the PWM signals. The inverter is capable of producing seven levels of output-volt...

Harmonics Analysis of Four Switch Three Phase Inverter

In the viewpoint of reliability implication and cost effectiveness of three phase inverter, there should be less device count in inverter topology and fewer losses in the semiconductor switches. The earlier reported less device count topology by many research groups are facing the problem of Total Harmonic Distortion (THD). The imperfect design value of DC link capacitor is the main reason of H...
