Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to a tram charging technology, in particular to a three-level power module system device and a charging system used in a tram station charging system. Background technique [0002] In the field of rail transit technology, especially on the ground charging system of trams, on the one hand, the time for vehicles entering and leaving the station is strictly controlled, and on the other hand, the charging voltage and power of entering the station are high. Based on the above two aspects, it is required that the ground charging system for trams can effectively reduce the charging time of trams, and at the same time provide high-voltage and high-power charging devices. Therefore, higher requirements are put forward for the power modules of the charging devices. The research and development of new power modules for this high-voltage, high-power fast charging system has become a new rese...
