The traditional single-switch circuit has the advantages of fewer components, no shoot-through problems, and suitability for high-frequency wireless charging applications. However, because high voltage stress switch, bulky inductor, narrow soft-switching range, its power applications have some limitations. To relieve this problem, paper proposes a pull-up active-clamping circuit, which not only...

The main aim of this study is to investigate the ageing process Low Voltage cables in smart grid. In addition, behavior phenomenon has also been investigated. cable networks were developed decades ago and it utmost importance make comprehensive over health existing so as avoid any unprecedented damage. Incessantly increasing energy demand distributed generation makes among top priorities cables...

This paper discusses the challenges of performing powered-up vector testing of low voltage technologies on In-Circuit testers and the safeguards that are necessary to ensure that test vectors do not violate the increasingly tight specifications of low voltage parts. Topics include why manufacturers are adopting low voltage technologies, what happens when low voltage components are exposed to st...

Previous studies indicated that stress and glucocorticoids have modulatory effects on acute pain. The aim of present study was to determine the interaction between stress and glucocorticoids with activation of voltage dependent Ca2+ channel on modulation of acute pain in mice. Male albino mice (25-30 g) were used for this experiment. Tail flick and hot plate were used for evaluation of analgesi...

Class-AB circuits, which are able to deal with currents several orders of magnitude larger than their quiescent current, are good candidates for low-power and high slew-rate analog design. This paper presents a novel topology of a class AB flipped voltage follower (FVF) that has better slew rate and the same power consumption as the conventional class-AB FVF buffer previously presented in liter...

Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...
