Harmonic Minimization in Grid Coupled Photovoltaic Structures Using Selective Harmonic Elimination Pulse-Width Modulation in Multiple Level Series Linked Nano-Scale Double Gate Hetero-Structure MOSFET Based H Type Bridge Inverters

Abstract

Semiconductor Chip makers and semiconductor device designers denote that, a reliable device should have a character with high speed and low power loss in its operation, which could be done in a nano-scale regime. A nano-scale double gate hetero-structure MOSFET based multilevel inverter is a power electronic arrangement system that generates multilevel output voltage with lower harmonic distortion and reduced power switching loss. In a grid-connected photovoltaic device, this power electronic inverter is a critical and essential component. Series coupled H-bridge multilayered inverter is a widely satisfactory arrangement for incorporation of renewable power among three multilevel inverter topologies, which might be directly fed by photovoltaic (PV) units, wind turbines, or fuel voltaic cells with enhanced power quality due to accessibility of an individual’s direct current sources. Furthermore, compared to traditional converters, this multilayered configuration will boost output voltage and current accuracy, resulting in lower total harmonic distortion. This concept proposes an innovative series of type H-bridge multilayered inverters arrangement for grid-connected photovoltaic structures. The optimization algorithm, particle swarm was incorporated to estimate the switching angles after the Selective Harmonic Elimination technique was developed to remove 5th, 7th, 11th and finally 13th lower number harmonics. For the first time, a cyclic choice method was used to keep up a constant balance of power among the different sources, in which the sources contribute equally to the output power over the course of operation. A simulation in the MATLAB/SIMULINK foundation was used to validate the integrated definition. The output taken from an experimental arrangement was used to verify the proposed principle of eradicating lower-level harmonics. The harmonic spectrum along with output waveforms for selective harmonic eliminated pulse-width modulation (SHE-PWM) technique was then obtained.
