Fixed Energy Storage Technology Applied for DC Electrified Railway

Induction Motor Characteristics and Applications for Dc Electrified Railway Systems

Induction motor structures in DC electrified railways with their dynamic performance are studied. Characteristics of the current, voltage, electrical and mechanical torque and active and reactive power in accelerating, normal and regenerative braking are investigated. The characteristics of the induction motors used for Tabriz urban railway are simulated with PSCAD/EMTDC software proving the in...

A Bidirectional DC-DC Convreter with Zero Voltage Switching Capability for Energy Storage Application

In this paper, a bidirectional DC-DC converter with high power density for energy storage application is proposed. The presented converter provides power transfer in both directions only with adjusting phase shift angle. Zero voltage switching (ZVS) in both turn on and turn off moments of all switches is the major capability of the converter that makes it suitable for high power applications. Z...

Bidirectional DC-DC Converters for Energy Storage Systems

A Bi-Directional DC/DC Converter for Energy Storage Systems

This paper addresses a bi-directional dc/dc converter suitable for an energy storage system with an additional function of galvanic isolation. An energy storage device such as an electric double layer capacitor is directly connected to one of the dc buses of the dc/dc converter without any chopper circuit. Nevertheless, the dc/dc converter can continue operating when the voltage across the ener...
