<b>DC-DC Converter Control Method for High Voltage DC Feeding System to Improve Use of Regenerative Power</b>

A high voltage DC feeding system, which consists of higher-voltage feeders and DC-DC converters in addition to an existing circuit, is assumed improve the performance power supply trains without changing nominal contact lines onboard traction systems. In this method for controlling converter important element must be taken into consideration maximize energy savings. paper, we propose a control make ratio constant between line feeder. system with called "DC-AT system." We evaluated savings through simulation, case studies on model confirmed that can reduce consumption by 4.5% at most, average 3.5%, compared conventional
