This article describes the Voltage swell and overvoltage compensation problems in a diode-bridge rectifier supported transformerless-coupled
dynamic voltage restorer (DVR). applying conventional in-phase or phase-invariant boosting method in case of condition of swell or overvoltage, may cause a a rapid rise in dc-link voltage which may ultimately lead to the damage of the storage capacitors and switching devices, and increase the switching loss. The minimum energy injection scheme is unable to solve these problems. Here, a novel unidirection ....etc

Overvoltage protection concept for DC railway systems
ABSTRACT
Overvoltages in electrical networks result from the effects of lightning strokes and switching actions and cannot be avoided. Furthermore, the power supply of electrical railways is endangered by direct or nearby lightning. A new device, combining protection against overvoltages and touch voltages and protection of people is introduced. Protection concepts for DC railway systems are introduced, considering the different insulation of ....etc

ABSTRACT
Aim of this project is control the unmanned rail gate automatically using embedded platform. Today often we see news papers very often about the railway accidents happening at un- attended railway gates. Present project is designed to avoid such accidents if implemented in spirit. This project utilizes two powerful IR transmitter and two receivers, one pair of transmitter and receiver is fixed at upside (from the train comes) at a level higher than human being in exact alignment and similarly other pair is fixed a ....etc
