Abstract

The paper introduces development works of a bilateral DC/DC converter rated at 1500V with peak power 500kW for battery energy storage systems supporting railway DC feeder systems. The DC/DC converter converts the regenerated power from the breaking train and to charge the batteries. The DC/DC converter discharges the stored energy to feed the powering train. The paper describes the converter main circuit, the control system and successful test results at the factory. For the main circuit test, a special test method is applied. For the control system test, a real time digital simulator is used for hardware-in-loop test. In addition to the converter tests, results from the DC feeder system tests with an actual rectifier and a battery bank are also introduced.
