DC-DC Power Converters


introduction

Dc-dc power converters are employed in a variety of applications, including power supplies for
personal computers, office equipment, spacecraft power systems, laptop computers, and
telecommunications equipment, as well as dc motor drives. The input to a dc-dc converter is an unregulated
dc voltage Vg. The converter produces
a regulated output voltage V, having a
magnitude (and possibly polarity) that
differs from Vg ....etc

The Switched Reluctance Generator for Wind Power Conversion

The use of wind energy has become increasingly important as a renewable energy source, so there is an increasing interest in exploiting it using a Switched Reluctance Machine (SRM).

Introduction

In the last decades, the SRM serves as an important alternative in various applications both within the industrial and domestic markets, as a motor showing good mechanical reliability, high torque-volume ratio and high efficiency,and it is of low cost.Eventhough SRM is easy to build ....etc

Am rema,want to know about an efficient common mode hybrid filter used in SMPS for my seminar work.


Abstract obtained from IEEE is After the study of electromagnetic interference (EMI)
mechanisms in switching mode power system (SMPS) and the soft
switch, this paper proposes a novel hybrid filter (HEF) to suppress
commend mode EMI in SMPS. The HEF consists of a passive filter
and an active filter. Matching network, which can reduce
impedance mismatching effects, is introduced in passive part. A

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:

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 cur ....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
