Conventionally, DC arc furnaces are fed by thyristor rectifiers to control the level of current or power transferred load. With advancement high-power transistors, other structures such as diode and choppers have been introduced developed for feeding system electric furnaces. In this paper, effect different supply systems on quality indexes is discussed. regard, two types considered, including ...

Developing countries often have access to limited energy resources, which frequently results in power cuts and failures. During these power cuts, enterprises rely on backup sources for power such as uninterruptible power supplies (UPS) and electric generators. This paper proposes AnywareDC, an architecture that builds on the recent work on Anyware [6] to reduce energy utilization in the presenc...

The CLEO III detector has recently commenced data taking at the Cornell electron Storage Ring (CESR). One important component of this detector is a 4 layer doublesided silicon tracker with 93% solid angle coverage. This detector ranges in size and number of readout channels between the LEP and LHC silicon detectors. In order to reach the detector performance goals of signal-to-noise ratios grea...

While ultra-deep-submicron design presents increasingly difficult challenges for standard synchronous design practices, recent research in asynchronous design techniques is making asynchronous circuits an increasingly practical alternative. These challenges include the increasing pressure for low-power, the growing challenge of predicting increasing impact of wire load and delay, and the perfor...

This white paper targets power supply engineers and managers alike by providing measurable data in favor of switching to digital power supplies. A power supply designer will find novel implementation ideas to easily achieve and exceed design objectives. Based on the many benefits of digital power described in this white paper, engineering managers will be able to make an informed decision and c...

Introduction This detailed section contains an in-depth explanation of the numerous PWM functions, and how to maximize their usefulness. It covers a multitude of practical circuit design considerations, such as slope compensation, gate drive circuitry, external control functions, synchronization, and paralleling current mode controlled modules. Circuit diagrams and simplified equations for the ...
