“…Switches Q1, Q3, Q2, and Q4 are arranged in sequence in this configuration in standard H-bridge circuit. Both gating signals GQ1 and GQ4 are switched together at positive half cycle while gating signals GQ2 and GQ3 are switched together at the other half cycle [24][25][26][27][28]. The switching signals GQ1 and GQ4 lead the switching signals GQ2 and GQ3 by 180 degrees (half cycle) of the switching control signal.…”

This paper offers a two-stage boost converter for a single-phase inverter without transformer for PV systems. Each stage of the converter is separately controlled by a pulse width modulated signal. A Simulink model of the converter using efficient voltage control topology is developed. The proposed circuit performance characteristics are explained and the obtained simulation results are confirmed through the applied experiments. Moreover, this paper has examined the control circuit of a single-phase inverter that delivers a pure sine wave with an output voltage that has the identical value and frequency as a grid voltage. A microcontroller supported an innovative technology is utilized to come up with a sine wave with fewer harmonics, much less price and an easier outline. A sinusoidal pulse width modulation (SPWM) technique is used by a microcontroller. The developed inverter integrated with the twostage boost converter has improved the output waveform quality and controlled the dead time as it decreased to 63 µs compared to 180 µs in conventional methods. The system design is reproduced in Proteus and PSIM Software to analyze its operation principle that is confirmed practically.

“…This results in a more reasonable design constraint but at the cost of slightly higher harmonic distortion. The relationship between slower turn on/off and the increased harmonic distortion was investigated in the literature both from the perspective of grid-tie inverter technology [18][19][20], but also from the perspective of switching time and dead time related harmonic distortion in class D amplifier design [21,22]. This yielded no feasible method for predicting the harmonic distortion in a generalised case.…”

Focusing on cascaded H-bridge converters for grid-tie battery energy storage, a practical, analytical method is derived to evaluate the switching-associated power loss in multilevel converters, evaluated from a number of sources of loss. This new method is then used to find performance trends in the use of converters of increasing order over a range of switching frequencies. This includes an experimental analysis into predicting the performance of MOSFET body diodes. Authors' analysis with this model shows that a multilevel converter can have lower losses than the equivalent single-bridge, three-level converter, particularly at higher switching frequencies, due to the availability of suitable switching devices. It also has interesting implications for enabling the use of cutting-edge non-silicon power switching devices to further improve potential efficiencies.

“…For this purpose, various algorithms are used for harmonic elimination in PWM (Rai and Chakravorty, 2019; Bouhali et al , 2005; Sirisukprasert et al , 2002; Babaei and Rastegar, 2017). The selective harmonic elimination (SHE) technique is the most effective method from these algorithms (Bose, 2003; Saied et al , 2008; Jahmeerbacus and Sunassee, 2014; Wenyi and Zhenhua, 2015; Hao et al , 2021; Kirti and Goyal, 2017; Hendawi, 2015; Wu et al , 2021; Dahidah et al , 2014).…”

Purpose This study aims to present the experimental results for neural network (NN) based harmonic elimination technique for single-phase inverters. Design/methodology/approach Switching angles applied to power switches are determined using the NN technique based on the harmonics to be suppressed. Thus, besides controlling the output voltage, NN controller provides elimination of predetermined harmonics from output signal of single-phase inverter. Simulation and experimental results for the elimination of 15 and 20 low-order harmonics are presented. The switching angle values calculated by a NN , fuzzy logic and Newton–Raphson are compared for elimination of first 10 harmonics. Findings This paper provides the harmonic spectra showing that first 15 and 20 harmonics are suppressed from output signal. The NN is proved to give closest results to angle values calculated by Newton–Raphson’s numerical solution method. Originality/value The value of this paper is to verify the simulation results with the experimental result for the elimination of 15 and 20 low-order harmonics. Both the simulation and the experimental results demonstrate the success of the NN based selected harmonic elimination.
