01 Jan 2015TL;DR: The proposed nine level hybrid H-bridge inverter with solar-wind energy using hybrid asymmetric switching scheme of Pulse Width Modulation Technique (PWM) by providing high switching frequency with reduced number of switches will highly reduce total harmonic distortion and suppress lower order harmonics.
Abstract: Everything in this world is for easy living of human beings. The objective of this paper is to propose a novel hybrid H-bridge inverter control for electricity from Photovoltaic (PV)-Wind energy system in order to simplify the power system and reduce harmonics and the cost effect. This inverter has advantageous of industrial application. The conventional use of converters will increase losses and cost in conventional methods. The proposed nine level hybrid H-bridge inverter with solar-wind energy using hybrid asymmetric switching scheme of Pulse Width Modulation Technique (PWM) by providing high switching frequency with reduced number of switches will highly reduce total harmonic distortion and suppress lower order harmonics confirmed by MATLAB/simulink tool as well as hardware results by using Power quality analyzer.

TL;DR: The title compound, C10H9FN4S, crystallizes with two molecules (A and B) in the asymmetric unit, and features an intramolecular C—H⋯S hydrogen bond, which closes an S(6) ring.
Abstract: The title compound, C10H9FN4S, crystallizes with two mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the planes of the trizole and fluoro-benzene rings is 7.3 (3)° in mol-ecule A and 41.1 (3)° in mol-ecule B. Mol-ecule A features an intra-molecular C-H⋯S hydrogen bond, which closes an S(6) ring. In the crystal, A+B dimers linked by pairs of N-H⋯S hydrogen bonds occur, generating R 2 (2)(8) loops. Weak π-π stacking contacts [centroid-centroid separation = 3.739 (6) A] are also observed.

TL;DR: The title compound, C17H12FO, a derivative of the anti-oxidant, anti-bacterial and anti-inflammatory compound curcumin, crystallizes with three independent mol-ecules (A, B and C) in the asymmetric unit.
Abstract: The title compound, C17H12FO, a derivative of the antioxidant, antibacterial and anti-inflammatory compound curcumin, crystallizes with three independent molecules (A, B and C) in the asymmetric unit. Molecule C is found to have whole-molecule disorder with an approximate 2:1 ratio of occupancies. The mean planes of the two 4-fluorophenyl groups in A, B and C form dihedral angles of 54.8 (2), 54.3 (1) and 52.4 (8)°, respectively. The angles between the mean plane of the penta-1,4-dien-3-one group and those of the two 4-fluorophenyl rings are 26.9 (3) and 33.7 (7)° in molecule A, 25.3 (1) and 34.2 (6)° in B, and 28.0 (9) and 30.8 (1)° in C. The crystal structure is stabilized by intermolecular hydrogen bonds.

TL;DR: In the title molecule, C15H11Br2ClO2, an S(6) ring motif is formed via an intramolecular O—H⋯O hydrogen bond, which links the molecules into chains along the c axis.
Abstract: In the title molecule, C15H11Br2ClO2, an S(6) ring motif is formed via an intramolecular O—H⋯O hydrogen bond. The dihedral angle formed between the chloro- and hydroxy-substituted benzene rings is 34.10 (15)°. In the crystal, weak intermolecular C—H⋯O hydrogen bonds link the molecules into chains along the c axis.

06 Mar 2020TL;DR: Evaluating the results and validate that Increment conduction Algorithm gives better performance of PV water pumping system compared to the scheme with Purtueb Observe (P&O) algorithm, shows the better performance interms of efficiency under the different weather conditions.
Abstract: This research provides a description of the designs and simulation of the effective photovoltaic water pumping framework utilizing the PI and Fuzzy Logic Controller (FLC). The framework uses a maximized power point tracking method (MPPT) using P & O and Increment conduction Algorithm. The proposed system consists of boost converter, battery, inverter and submersible pump. The generation of gate pulse for boost converter using PI with FLC along with MPPT techniques and for inverter circuit using sinusoidal PWM technique. The proposed methods were simulated using MATLAB Simulink setting and associate the presentation of projected system. The evaluating the results and validate that Increment conduction Algorithm gives better performance of PV water pumping system compared to the scheme with Purtueb Observe (P&O) algorithm. Two MPPT techniques were compared and analyzed using MATLAB simulink environment. The incremental conduction algorithm shows the better performance interms of efficiency under the different weather conditions.
