This paper presents the application of genetic algorithm to determine optimized pulse patterns in multilevel inverters aiming to mitigate harmonics generated at the inverter output voltage while maintaining a desired modulation index. A new real representation based on a relative position approach is applied to the chromosome encoding in order to avoid the existence of infeasible solutions and a systematic diversity control of initial population is proposed based on the euclidean distance between individuals. A local search mechanism combined with an elitist selection is also considered. Fitness value frequency distribution, waveform patterns and its corresponding harmonic components are presented to illustrate the effectiveness of the proposed algorithm.

“…In most works, e.g., Dahidah and Agelidis (2008), Bindu et al (2011), Zhang et al (2014) and Chatterjee et al (2017), the solution space is first randomly populated. This does not prevent the coexistence of similar individuals in the initial population.…”

“…The number of equations increases because the switching angles increase with the higher number of modules. The authors of [30], [34][35][36] proposed many equation-solving methods like the Newton-Raphson (NR) method, particle swarm optimization (PSO), and genetic algorithms (GA) to ease the calculation of the switching angles. Regardless, it is challenging to solve these nonlinear equations for more modules.…”

Cascaded H-bridge multilevel inverters (CHB-MLI) are employed in a variety of medium/high power applications. These inverters are known to inject unwanted harmonics into the grid, which negatively affects the grid and connected loads. CHB-MLI topology can reduce many of these harmonics by producing multiple output voltage levels and improves the fundamental component using a suitable modulation technique. However, the CHB-MLI topology configuration requires multiple isolated input sources which must be balanced either with the modulation technique or with an additional method. This paper analyzes multi-carrier pulse width modulation (MC-PWM) techniques for CHB-MLIs. In this study, two basic configurations of CHB-MLI symmetrical and asymmetrical are reviewed, followed by their mathematical analysis. Also, this paper analyses multicarrier based sinusoidal pulse width modulation (MC-SPWM) and multi-carrier based third-harmonic injected pulse width modulation (MC-THIPWM) techniques with phase-shifted (PS) and level-shifted (LS) carrier arrangements for the CHB-MLI. Moreover, a simulation study has been conducted using MATLAB Simulink to analyze the performance of MC-PWM techniques for the symmetrical and asymmetrical type CHB-MLIs. The 7-level and 9-level CHB-MLIs were evaluated for the stated MC-PWM techniques in terms of harmonics and fundamental components. In addition, discharging current of all input sources was checked to verify the ability of all MC-PWM techniques to balance all input sources.

“…The front‐end AC‐DC PFC converter plays a vital role in providing regulated DC link voltage to the flyback converter and maintaining input side power quality as per IEC 6100‐3‐2 standards and SAEJ2894 1 . As Diode Bridge Rectifier (DBR) is used in front end of AC‐DC power conversion, the input current drawn from the AC supply is highly polluted with harmonics 12 . The main focus of this work is designing a high‐efficient front‐end AC‐DC PFC converter for EV on‐board charger.…”

Summary This paper proposes a modification in the interleaved negative output elementary Luo converter to act as front‐end power factor correction converter for on‐board electric vehicle (EV) charger. The proposed converter is simple in design and offers non‐inverted DC link output voltage. The proposed converter has the advantages—high efficiency, near unity power factor, low AC source current distortion resulting in power quality enhancement, better DC load voltage regulation, and reduced component count. Due to interleaved configuration, rating of circuit components gets greatly reduced. Also, minimum numbers of circuit components pave the way for simple system design of on‐board EV charger. The steady‐state performance of the designed 100‐W, 48‐V converter with closed‐loop controller is analyzed under universal input voltage variation and wide range of load power variation. The converter is designed to provide stable operation when subjected to sudden disturbance in load power/supply voltage. The simulation analysis is done using MATLAB/Simulink platform. A prototype of 48‐V, 100‐W converter is built and tested. Results obtained reveal the superior performance of proposed converter under steady‐state and transient conditions.
