It takes the high-power converter as the core, applies the three-phase current dynamic adjustment technology, changes the traditional series connection mode to parallel connection mode, and saves a lot of construction costs. Furthermore, it has the additional functions of harmonic filtering, reactive power compensation and neutral line current suppression. The ground power supply is connected to the low-voltage busbar in parallel without the need to configure a switching device or lay a second power supply cable, which may reduce the project cost. System composition: train station ground power supply, ground power supply socket box, information system.
