The proposed 12-pulse controlled rectifier is used to supply high power industrial loads. It can regulate the output dc voltage; Its ability to effectively and cheaply mitigate the harmonics on the ac side has ensured its dominance in the industry even as active front ends become cheaper and more reliable. Despite its many benefits, the 12pulse controlled rectifier is not able to reduce the ac-...

Supply of uninterrupted sinusoidal voltage of constant magnitude is the most important aim of the electrical distribution system, but this task is very tough and is becoming more difficult due to the increasing size and number of nonlinear and poor power factor loads. Some of the most important causes of poor power quality is harmonics and high neutral current. Harmonics and neutral current det...

This paper proposes the improved methodology of power quality in grid interconnected photo voltaic system by using shunt active power filter . With development of new functionalities solar energy based Photovoltaic cells are upcoming energy source with higher efficiency. Solar energy being naturally available in abundance and nonpolluting is one of the most promising sources. Excessive use of p...

The frequency-dependent nonlinear dielectric increment of dipolar fluids in nonpolar fluids is often measured by using a stationary relaxation method in which two electric fields are used: The static direct current (dc) field of high strength causing the dielectric nonlinearity, and the probing alternating current (ac) field of low strength and high frequency. When a nonlinear composite is subj...

Abstract The winding current harmonic content of converter transformer in operation is rich. However, affected by harmonics, the radial vibration characteristics are quite different from power transformer, structural loosening and deformation caused more prominent. Therefore, view influence harmonics on axial vibrations, this study builds a 3D electromagnetic finite element simulation model, an...
