“…A MOSFET circuit is used to improve DC-AC conversion efficiency. The paper [15] used a microcontroller and a cascaded H-bridge topology to improve the efficiency and reliability of systems used in multilevel solar PWM inverters. We also recognize the need to track the maximum power point for efficiency.…”

This is a new configuration of single-phase hybrid inverter with integrated battery energy storage suitable for residential use in this white paper to maximize local consumption of solar energy and reduce reliance on support . A hybrid inverter is called a Direct Storage Hybrid (DSH) inverter. Connect photovoltaic (PV) panels to loads and grids using transformerless topologies such as HERIC, which operate at low frequencies and produce three-level square wave output voltages. An active series filter is used to cancel the harmonic content from the square wave voltage and provide a sinusoidal voltage. A bi-directional DC/DC converter connects the battery to the PV panel and controls the charging state of the battery (SoC), optimizing the operation of the PV panel in both off-grid and grid-connected modes. The DSH inverter bypasses the battery DC/DC converter and can be connected directly to the inverter stage, greatly increasing throughput efficiency when using batteries. This document presents his DSH inverter operation and loss analysis in off-grid mode.

“…An analytical approach is also examined in this of type inverter structure to provide the stability of the system [7]. Modeling, analysis, and design studies of grid-connected inverter structures are also investigated in PV integrated applications [8][9][10]. A grid-connected inverter structure is also evaluated in microgrid applications [11].…”

The energy demand has been increasing over the last decade. With the integration of renewable energy sources, grid-connected inverters play a key role in a power system. The main objective of the paper is to discuss a grid-connected inverter with single-phase structure in particular. The design and working principle of a basic grid-connected inverter are presented together with the cycle-by-cycle average (CCA) model. The LCL filter design is also introduced to decrease the current harmonics. To attain unity power factor operation, the closed loop control is essential for the grid-connected inverters. For this reason, a current controller in dq-frame is performed by utilizing MATLAB/Simulink environment. The results indicate that the suggested current controller presents good performance during the variations. This study is anticipated to draw the attention of grid-connected inverter designers and serve as a reference for them.

“…Particularly, these wastes make the high-end warming and threatening for developed and developing countries in our globe for both of aquatic and non aquatic environment whereas it must be reported that more than 30% natural environment had been destroyed last five decades [1,2]. First of all, the annual water marks was found to be 1.8 billion m 3 for only textile industry, and other industries consumed more than this amounts. The total amount of water was taken from the ground water which may result in depletion of groundwater level, other side it can lead to major health problems for the local people.…”

“…Secondly, in case of domestic sewage, about 13468 minimum liquid discharge (MLD) of wastewater has been generated by overall industries, and 60% of that is treated for removal the toxic chemicals. Laila Hossain et al 2018 reported that about 23% fresh water will be reduced due to only textile industries water consumption in Bangladesh although Bangladesh is considered the 2 nd largest exporter country in our globe [3]. The other rationale is noted for waste water from textile industries that the organic dyes and pigments with polymers or fabrics are the vital contributor for producing such waste, and all of these are highly toxic for both aquatic and non aquatic living organisms.…”

For developing the stannite type quarterly crystal photocatalyst, the electronic structure and optical properties of ZnAg 2 GeSe 4 , ZnAg 2 Ge 0.93 Fe 0.07 Se 4 and ZnAg 2 Ge 0.86 Fe 0.14 Se 4 were calculated and compared with the parent stannite type quarterly crystal, ZnAg 2 GeS 4 . First of all, the four functionals, such as GGA with PBE, GGA with RPBE, GGA with WC and LDA with CA-PZ functionals were used for primary screening of electronic band structure and structural geometry for ZnAg 2 GeS 4 while the band gap was in 0.93, 0.97, 0.77 and 0.67 eV, respectively. It must be mentioned that the experimental value of ZnAg 2 GeS 4 was 0.94 eV so that the GGA with PBE showed the overlapping value of band gap. The main focus of this paper is to evaluate the band structure of newly predicted the stannite type quarterly crystal, ZnAg 2 GeSe 4 using four methods replacing the Sulfur atom by Serium atom on ZnAg 2 GeS 4 . The band gap for four methods, such as GGA with PBE, GGA with RPBE, GGA with WC and LDA with CA-PZ functionals, were calculated in 0.84 eV, 0.92 eV, 0.68 eV and 0.58 eV. Afterward, Fe atom was doped by two portions, like 7% and 14%, to make the empirical formula, ZnAg 2 Ge 0.93 Fe 0.07 Se 4 and ZnAg 2 Ge 0.86 Fe 0.14 Se 4 . The numerical values of band gaps for ZnAg 2 Ge 0.93 Fe 0.07 Se 4 and ZnAg 2 Ge 0.86 Fe 0.14 Se 4 were 0.43 eV, 0.53 eV, 0.35 eV and 0.18 eV and 0.24 eV, 0.31 eV, 0.18 eV and 0.08 eV, respectively, using the four respected DFT methods. For their contributed orbitals of each atom on crystal, the density of state and the partial density of state for ZnAg 2 GeSe 4 , ZnAg 2 Ge 0.93 Fe 0.07 Se 4 and ZnAg 2 Ge 0.86 Fe 0.14 Se 4 crystals were simulated through the GGA with PBE method as standard regarding the calculation of band gap study comparison with experimental magnitude. For giving the further information about the nature in case of optical evidence, the six optical properties, such as absorption, reflection, refractive index, conductivity, dielectric function and loss function were calculated, and make a comparative study. In case of UV light absorption in lighten to optical parameters, the ZnAg 2 Ge 0.86 Fe 0.14 Se 4 can show the highest absorption up to convenience energy region as photocatalyst.
