| Abstract | The present invention relates to an uninterruptible power supply system for neutral section passing of a power-centralized motor train unit trailer, comprising an inverter, a trailer AC load, a charger, a storage battery pack, and an emergency power supply. Before a train passes through a neutral section, the total power of the trailer AC load is reduced, a train power supply is turned off, and electric energy of the storage battery pack is boosted by the emergency power supply and inverted by the inverter to supply power to the trailer AC load; after the train passes through the neutral section, the trailer AC load is switched to be powered by the train power supply, and storage batteries are charged by the train power supply to ensure uninterrupted power supply during next neutral section passing. By using the uninterruptible power supply control scheme of the present invention, the trailer can be not limited by the train running speed and the train power supply, and uninterrupted power supply for the trail |
