The wind energy conversion system (WECS) differs from other power systems. It is clean and pollution free. But the output of wind power plant is fluctuated in nature. It depends on the wind speed. The nature of wind is variable. The variable wind generates fluctuated power. Fluctuated output is the major problem of wind power plant. This problem can be solved by using convertor units. The secon...

High energy photons can be generated via inverse Compton scattering (ICS) in the collision between energetic electrons and intense laser pulse. The development of plasma accelerators promises compact all-optical gamma-ray sources by colliding from wakefield to its high-power driving pulse reflected a mirror. However, law optical focusing hinders realization both high photon yield monochromatic ...

in this paper, a new method is introduced for improving the efficiency of the residue number system, which uses both binary and residue representations in order to represent a number. a residue number system uses the remainder of the division in several different modules. conversion of a number to smaller ones and carrying out parallel calculations on these numbers greatly increase the speed of...

IC A IO N We have been working on “self-powered nanotechnology” since 2005 with the aim to build self-powered systems that operate independently, sustainably, and wirelessly without the use of a battery. [ 1 , 2 ] One of the great applications for such a self-powered system is that it can be used for driving portable/wearable personal electronics in our daily life. Nanogenerators (NG) are one o...

Voltage to current converters or TRANSCONDUCTANCE amplifiers, find its applications in both traditional analog ICs e.g. amplifier and filters as well as current analog VLSI e.g. Field programmable analog arrays and various other neural networks. A complete review of different linear V-I converter has been done in this paper. Since the basic V-I convertor circuit uses common source differential ...

A self-sustained multi-sensor platform for indoor environmental monitoring is proposed in this paper. To reduce the cost and power consumption of the sensing platform, in the developed platform, organic materials of PEDOT:PSS and PEDOT:PSS/EB-PANI are used as the sensing films for humidity and CO₂ detection, respectively. Different from traditional gas sensors, these organic sensing films can o...

This paper summarizes the development of the synchronization control technology of the multi-motor control system. And a model structure of multi-motor synchronization control system based on the monomaster PROFIBUS-DP network is proposed, which slaves are intelligent including PLC, convertor and motor. The communication mode of MS is adopted. The control tasks of the master and their slaves ar...

In this paper a new high gain bandwidth (GBW) and low power folded cascade OPAMP is presented. It has been implemented and layouted by CADENCE software in 0.18μm. Its DC gain is 82db and its bandwidth is 200MHz. Power consumption is one of the main design challenges in very-lowvoltage high-speed analog integrated circuits. In this paper, different techniques to reduce the power consumption in l...
