Charging infrastructure for electric vehicles (EV) will be the key factor for ensuring a smooth transition to e-mobility. This paper focuses on five technologies that will play a fundamental role in this regard: smart charging, vehicle-to-grid (V2G), charging of EVs from photo ...
Magnetic cores like powdered iron cores have a variable permeability, which is dependent on the magnetic motive force of the inductor windings. When inductors are designed using such materials, the inductance varies as a function of the inductor current. This causes a non-linear

This paper describes the development of a simple maximum power extracting (MPE) scheme for Wind Electric Energy Conversion System (WECS) comprising of an induction generator, capacitor banks, a diode bridge rectifier, dc link inductor and a line commutated inverter feeding the ...
An Audio Frequency Track Circuit (AFTC), a recent addition to railway signalling, confirms the absence of a train in a section of track. While the basic concept is established, several issues relating to proper operation of the AFTC need theoretical study. Installation practices
