要約(英語): A high-voltage DC feeding system, which consists of higher-voltage feeders and DC-DC converters in addition to the existing feeding circuit, can be used to supply vehicles power with a conventional feeding voltage. In this system, it is important to consider the control method of the converter to maximize the energy savings. Here, we propose a converter control method to make the voltage ratio between the overhead contact line and the higher-voltage feeder constant and named the DC-AT control method. Furthermore, we devised a load sharing control that reduces cases where a specific converter momentarily becomes a high load, by sharing the power transfer between multiple converters, and reduced the rated power of the converter. In addition, we confirmed the effectiveness of the proposed control method via simulations, demonstrating that excellent energy savings by promoting the interchange of regenerative power and the suppression of the high load of the converter could be achieved simultaneously.
