Abstract

Battery supplies Each Electric device in Railway vehicles with Control Power. When Battery is overchargedjustly, the battery voltage is not satisfied with the minimum operating voltage, CVCF Inverter(SIV) is supplied with external Power supply or the other railway vehicles and start up CVCF Inverter. In this paper to improve this problem, Dead battery Starter system is proposed. When the battery voltage is not satisfied with the minimum value.turn on the Dead Battery Starter switch, and the Dead Battery Starter supplies the control power to the SIV controller from the line voltage. With this Dead Battery Starter system, the train can be operated when the battery is not proper status. Dead Battery Starter is designed by ROTEM and will be delivered to Attiko Metro Series 2.
