Research on Harmonic Suppression Strategy of Grid - Connected Inverter Based on Power Grid Background Harmonics

2018 International Conference on Engineering Simulation and Intelligent Control (ESAIC), 2018
The current quality is an important indicator to evaluate the performance of a grid-connected inverter. In practice, many factors including the grid voltage distortion, dead-time effect, non-ideal switches and dc-link disturbances would result in many low-order harmonics in the injected grid current.

Vacuum harmonic generation in slowly varying electromagnetic backgrounds

2016
Relativistische Quantentheorie sagt die Existenz von virtuellen Elektron-Positron-Paaren vorher, die innerhalb einer typischen Zeitskala, der Compton-Zeit des Elektrons, erzeugt und wieder vernichtet werden. Diese virtuellen Dipole machen das Vakuum zu einem polarisierbaren Medium, was zu einer Abänderung der klassischen Maxwell-Gleichungen führt ...

Harmonics distribution of iron oxide nanoparticles solutions under diamagnetic background

Journal of Magnetism and Magnetic Materials, 2018
Abstract The static and dynamic magnetizations of low concentrated multi-core iron oxide nanoparticles solutions were investigated by a specially developed high- T c Superconducting Quantum Interference Device (SQUID) magnetometer. The size distribution of iron oxide cores was determined from static magnetization curves concerning different ...

Background-Free Second-Harmonic Generation Microscopy of Individual Carbon Nanotubes

Nonlinear Optics, 2015
We use polarized second-harmonic generation (SHG) microscopy to investigate pristine air-suspended carbon nanotubes (CNT). We show that SHG originates from CNT chirality, allowing also different response for the two circular polarizations of fundamental light.

Harmonized 'Goods and Service Tax' in India: A Backgrounder

SSRN Electronic Journal, 2012
The later half of the twentieth century has been witness to the transformation of the turnover and sales taxes to value added taxes (VAT). This trend which began in France in 1954 has been emulated with success in both the developed and developing countries and also at supra-national levels such as the EC-VAT.

Harmonic background amplification in long asymmetrical high voltage cable systems

Electric Power Systems Research, 2018
Abstract This paper presents an analysis of a harmonic problem encountered on the Danish island of Anholt and its mitigation. Time synchronized power quality measurements are presented at transmission and island nodes. Harmonic phase gain factors are calculated from the transmission system to the island and a simulation model is constructed and used ...
