Abstract


The aim of this project is to design a hydro-pneumatic power press using low cost automation.
This project mainly emphasizes on reduction of working time and labor cost. The working time should be reduced in order to increase the productivity of any industry. Labor cost reduction is also very important nowadays, so that even small scale industries can afford to go for automation.
The press ....etc

Abstract—

This paper proposes a new soft-switched continuousconduction- mode (CCM) boost converter suitable for high-power applications such as power factor correction, hybrid electric vehicles, and fuel cell power conversion systems. The proposed converter achieves zero-voltage-switched (ZVS) turn-on of active switches in CCM and zero-current-switched turn-off of diodes leading to negligible reverse-recovery loss. The components’ voltage ratings and energy volumes of passive components of the proposed converter are greatly reduce ....etc

Multilevel voltage source converters are emerging as a new breed of power converter options for high-power applications. Here, staircase voltage wave is generated from several levels of dc capacitor voltages. the voltage unbalance between different levels is the major disadvantage of multilevel converters. voltage clamping or capacitor charge control are the main techniques used to solve this. The following types of multilevel voltage source converters are described here:
a)diode-clamp: The diode-clamp method can be applied to highe ....etc

ABSTRACT
The aim of this paper is to describe the implementation of a lowpower,low-cost 16-bit RISC microcontroller that will act as thecore of a stand-alone security system. The controller is designedto provide moderate-high security at very low cost and to be ableto operate independent of a database. It is designed using 1.5-mSCMOS process from MOSIS and operates at a frequency of 12.5MHz.

LOW-POWER LOW -AREA MULTIPLIER BASED ON SHIFT AND ADD ARCHITECHTURE
Multipliers
Multipliers are among the fundamental components of many digital systems
The largest contribution to the total power consumption in the multiplier is due to the generation of partial product
Among all the multipliers shift and add multipliers are the most commonly used ,due to its simplicity & relatively small area requirement
