Due to their non-linear load characteristics, train locomotives play a significant part in the installation of railway electrification India and around world. Numerous techniques have been researched used with both AC DC enhance power quality. The development is this research provide viewpoint on various quality issues as well explore demand for problems system requirements acceptable many sort...

Abstract Electric vehicles (EVs) are without a doubt one of the hottest topics our time because their advantages over combustion engine vehicles. This has persuaded many developers to try improving EVs so they will be more reliable and cheaper as result suitable for broader range consumers. In this paper we dive into proper way measuring understanding impedance prismatic cell from 100 kHz up 1 ...

Ann R Coll Surg Engl 2012; 94: 359–372 Many lower extremity, pelvic and acetabular fractures require traction as first aid management prior to definitive fixation. While skin traction and Thomas splints are generally available, weights to provide countertraction are often missing or in parts of the hospital remote to the emergency department. A sharps bin (Sharpsguard® orange 11.5; Daniels, Oxf...

In this paper we consider a viscoelastic string whose deformation is controlled at one end. We study the relations and the controllability of the couples traction/velocity and traction/deformation and we show that the first couple behaves very like as in the purely elastic case, while new phenomena appears when studying the couple of the traction and the deformation. Namely, while traction and ...

<span lang="EN-US">Twelve-pulse rectification system had been widely integrated in today’s DC traction power sub-station (DC-TPSS). This configuration successfully mitigated low order harmonic distortion. As some research findings confirmed that the dc voltage and current ripple factors may further minimize by increasing number of pulses to 18, 24, or 36. paper presented a simulation stud...

This paper proposes a brain emotional learning based intelligent controller (BELBIC)for Interior Permanent magnet synchronous motor (IPMSM) drives used for traction application. The IPMSM is a suitable motor for traction because of its brushless, wide constant speed-power region and low power-loss operation. The operation of the BELBIC is based on the emotion processing mechanism in the brain. ...

Modern concepts of electrified drive trains for off-road vehicles allow for some new possibilities for control strategies. When considering traction efficiency, the most controllable factor is wheel-slippage. Many existing slip control systems use a certain threshold value of slip as reference, for example for farm tractors, electrohydraulic hitch control system (EHC) controls the implement, wh...

Abstract With the rapid development of economy and technology, people’s quality life has been continuously improved, which also makes people put forward higher requirements for transportation. As far as railway transportation is concerned, running speed route trains in past gradually failed to meet travel needs. Automatic train operation system (ATO), under protection automatic system, realizes...
