Distribution system plays an important role in supplying the electricity from generation to the consumers via transmission system. The power system is one of the most complex systems in the world. Because of the high R/X value the losses in the distribution system is more. The one of the roles of capacitor is reducing the losses in the distribution system. This paper presents an improved method...

This paper presents a 10-bit pipeline ADC using double sampling technique to achieve a conversion rate of 40 MS/s at 2.5-V supply. The opamps are two-stage with folded-cascode as the first stage and feature techniques such as common-mode stabilized active load, crosscoupled cascode connection, and close-loop pole placement. MOS switches are driven by bootstrapping circuits that do not subject t...

Loss minimization in power system is an important research issue. Transmission line losses in a power system can be minimized by means of reactive power compensation. The continuous demand in electric power system network has caused it to be heavily loaded leading to voltage instability. This phenomenon has also led to voltage profile depreciation below the acceptable secure limit. The signific...

The capacitance of a parallel plate capacitor is formulated in basic electrostatics, assuming that the separation between the two electrode plates is very narrow and the fringe field of the edges is negligible. However, in practical problems of electrical and electronic engineering there are many cases where the plate separation is wide and the fringe field effect cannot be neglected. In our pr...

Optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. The distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

This paper presents the Clonal selection algorithmic approach to minimize power loss and energy cost by optimal capacitor placement and sizing in Radial Distribution System (RDS). The clonal selection optimization for optimal capacitor allocation is considering the daily load curve, which is represented by a given number of load levels. As an important branch of the Artificial Immune Systems (A...

A non-volatile nanocrystal floating gate MOS capacitor with multi-level function is achieved by engineering the electric field within the tunneling oxide via a stepped control oxide. A MOS capacitor containing Au nanocrystals in a stepped HfO2 and SiO2 tunneling oxide matrix was fabricated in order to demonstrate this concept. The flatband voltage shift, measured from the C–V hysteresis curves,...
