To meet the emergency power supply capacity for daily servicing and maintenance of Electric Multiple Units (EMUs), and the emergency power supply capacity for lighting, heating, air conditioning, etc., of EMUs in the event of failure, the functional requirements for ground external power supply are usually considered in the design. In view of the special demand that a certain type of export EMU needs to be compatible with two external power supply modes, this study analyzes the selection of the maincircuit topology for the external power supply system, the selection of key parameters, and the external power supply’s adaptability to fluctuations, proposes corresponding control and protection strategies, and verifies the correctness of the external power supply scheme by MATLAB simulation.
