pdf files on a novel high step up dc dc converter for a microgrid converter

Abstract

A novel high step-up dc-dc converter for a distributed generation system is proposed in this paper. The concept is composed of two capacitors, two diodes, and one coupled inductor. Two capacitors are charged in parallel, and are discharged in series by the coupled inductor. Thus, high step-up voltage gain can be achieved with an appropriate duty ratio. The voltage stresses on the main switch and output diode are reduced by a passive clamp circuit. Therefore, ....etc

Abstract
The matrix converter is superior to the P W inverter drives because of its regeneration ability and sinusoidal input current. Therefore, it meets the stringent energy-efficiency and power quality requirements of the new century. This paper describes the basic operating principles and control method of the matrix converted; and reports the detailed experimental operating characteristics of an I1 kVA matrix converter drive over its full operating range. Through the experimental operating characteristics, t ....etc

IMPROVING RELIABILITY AND PERFORMANCE OF TRANSMISSION LINE USING FACTS TECHNOLOGY


INTRODUCTION :-
As generation and consumption of electricity has grown, investment in the transmission infrastructure has declined. The grid is aging and few new lines are being built, given high cost and permitting delays. The inability to control power flow on the grid results in poor asset utilization and impedes the growth of the energy market. Uncertainties in transmission investment recove ....etc

The switched varactor for high power RF signals is described in this article. This varactor can perform tuneable capacitor operations up to 10 GHz frequencies. The RF micro-electro-mechanical systems (MEMS) has become an atractive area of research in the recent. Devices like tuners, antenna beam forming networks and reconfigurable filters all will benefit from this.

Design principles
In the case of RF MEMS which depend on the electrostatic actuation have a a small air gap in the micrometer range between their movable membrane and ....etc

Abstract:
The modular multilevel converter (MMC) has been a subject of increasing importance for medium/high-power energy conversion systems. Over the past few years, significant research has been done to address the technical challenges associated with the operation and control of the MMC. In this paper, a general overview of the basics of operation of the MMC along with its control challenges are discussed, and a review of state-of-the-art control strategies and trends is presented. Finally, the applications of the MMC and their challenges a ....etc

Fuel Cell Plant Concept with Dynamic Characteristics of a Rotating Generator


Abstract Fuel cell plants will be powering future electrical
systems. Fuel cells normally generate direct current (DC) which
must be converted into Alternating Current (AC) for
transmission efficiency and for broader use by numerous loads of
different characteristics. An AC load consists of real power and
reactive power. The real power is generated by fuel cells.
However, the reactive power must be ....etc
