Railway locomotive is the core equipment of the railway transportation system, which undertakes the transportation function of the whole railway system, and is a veritable core device of transportation capacity. It plays an important role in the whole transportation system. The safety and reliability of railway locomotives is very important. It is necessary to add emergency devices in the power supply system other than the main power supply to ensure the power supply at emergency time. In this paper, the photovoltaic array is used as the main power supply, and the Boost + SIV circuit topology is connected at the back. The Boost and SIV are the intermediate DC bus voltage stabilizing link. The link is connected in parallel with a battery pack, which can realize emergency power supply when the light intensity is weak. The system adds a voltage sensor to achieve stable voltage output by control method, and adds a photosensitive sensor to achieve different working conditions of the power system under different light intensity, The experimental prototype is designed and verified.
