The Power Supply for EMU is a complete power system installed in EMU (Electric Multiple Unit) depots, specifically providing external power for EMUs under maintenance or parked in the depot. With high-power converters as the core, the power supply adopts three-phase current dynamic regulation technology, replacing the traditional series mode with a parallel mode, which significantly saves construction costs. It also features additional functions such as harmonic filtering, reactive power compensation, and neutral current suppression.

This ground power supply is connected in parallel to the low-voltage busbar, eliminating the need for switching devices or laying a second power supply cable, thereby reducing project costs. System composition: EMU Depot Ground Power Supply, Ground Power Socket Box, and Information System
