Abstract-

Comparator-controlled power switch has been widely used to improve power efficiencies of discontinuous-conductionmode (DCM) buck regulators. Some major design challenges are capabilities of the comparator to operate at low voltage and dissipate low power for low-voltage DCM ....etc

Abstract:

This project provides the experience of applying an advanced version of Spurious Power Suppression Technique (SPST) on multipliers for high speed and low power purposes. When a portion of data does not affect the final computing results, the data controlling circuits of SPST latch this portion to avoid useless data transition occurring inside the arithmetic units, so that the useless spurious signals of arithmetic units are filter out. Modified Booth Algorithm is used in this project for mul ....etc

circuit switched vs packet switched abstract seminar topic

In circuit switching network dedicated channel has to be established before the call is made between users. The channel is reserved between the users till the connection is active. For half duplex communication, one channel is allocated and for full duplex communication, two channels are allocated. It is mainly used for voice communication requiring real time services without any much delay

In packet switching network unlike CS network, it is not required to establish the connection i ....etc

BACKGROUND

The significance of power factor (PF) correction is reflected in the large number of documents addressing this subject, in the engineering design effort, and in the numerous industrial plants that manufacture equipment for the control of reactive power and filtering of current harmonics . Some of the benefits derived from correct PF adjustment are:
1. reduced energy loss;
2. released generation, transmission, distribution, and substation capa ....etc

HARBIN INSTITUTE OF TECHNOLOGY, CHINA


ABSTRACT:

Current mode implementation provides an alternative to high speed data conversion systems for low voltage applications. The pursuing of speed and accuracy of data conversion makes comparator critical. This paper presents a novel switched current (SI) comparator which achieves high speed without sacrificing either accuracy or power dissipation. Employing a class AB current mirror as the inp ....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 reduced c ....etc
