Abstract

The methods to stabilize power sources have been important issues in DC feeding circuits. A number of applications of energy storage have been investigated so far. In recent years, the development of energy storage media has been remarkable for drive-power supplies of electric vehicles. Therefore, the authors produced an energy storage prototype for a DC electric railway system that consists of electric double-layer capacitors, diode bridge rectifiers, a chopper system and PWM power converters. This paper describes its characteristics and experimental results of the prototype
