INTRODUCTION

The fully controlled converter can produce a reversible direct output voltage with output current in one direction, and in terms of a conventional voltage/ current diagram(Fig.1:) is said to be capable of operation in two quadrants, the first and fourth. Such a range of operation is useful for certain purposes, examples being the control of a dc torque motor, i.e. a motor used to provide unidirectional torque with reversible rotation (Fig.2), and a DC transmission page link between two AC systems in which power can be transmitted ....etc

Abstract

The present investigations relate to the development of TRIAC-DIAC based DC series motor speed controller for mud pumps of industrial drill-rig equipment. This paper deals with mud pumps on drilling rigs provide the means for supplying flow and pressure of the chemical mud fluid through the drill pipe, drill bit and return to the surface via the annulus of drill pipe. In this process, the mud maintains down-hole pressure, cools the drill bit and removes the cuttings from the well bore. Since flow is proportional to motor speed and pre ....etc

THREE PHASE DUAL CONVERTER
Introduction
Thyristor based three-phase controlled rectifiers are widely used in the industry for controlling dc motor drives. Controlled rectifiers offering power conversion from ac to dc are reliable and have higher lifetime compared to other converters. DC motors have higher torque than ac motors and hence are suitable for variable speed and speed reversing applications requiring high torques. Although the operation of controlled rectifiers is simple, the realization of the converter control circuit is complex i ....etc

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

speed control of dc motor using thyristor dual converter with pid controller

ABSTRACT

The paper describes the design, construction and testing of a closed-loop system for the speed control of a separately excited d.c. motor fed from a dual converter. The dual converter makes possible regenerative braking and reversal of direction of rotation. There is only one firing unit and the firing pulses are diverted to the appropriate converter by a master controller. There are three control loops: one for armature current control, one for adjusting th ....etc

A cycloconverter (CCV) or a cycloinverter converts a constant voltage, constant frequency AC waveform to another AC waveform of a lower frequency by synthesizing the output waveform from segments of the AC supply without an intermediate DC page link (Dorf 1993, pp. 2241 2243 and Lander 1993, p. 181). There are two main types of CCVs, circulating current type or blocking mode type, most commercial high power products being of the blocking mode type ....etc

single phase dual converter application

The high-level schematic shown below is built from six main blocks. The DC motor, the two single-phase full converters, and the bridge firing unit are provided with the Simscape Power Systems library. More details on these blocks are available in the reference sections of these blocks. The two other blocks are specific to the Electric Drives library. These blocks are the speed controller and the current controller. They allow speed or torque regulation. A regulation switch block allows you to toggle ....etc

Abstract
A new isolated current-fed pulse width modulation dc-dc converter-current-fed dual-bridge dc-dc converter-with small inductance and no dead time operation is presented and analyzed. The new topology has more than 3times smaller inductance than that of current-fed full-bridge converter, thus having faster transient response speed. Other characteristics include simple self-driven synchronous rectification, simple housekeeping power supply, and smaller output filter capacitance. Detailed analysis shows the proposed converter can have eit ....etc
