The invention discloses a charging device applied to charging of multiple types of new energy carriers. The device provides a plurality of different models of power and voltage output modules, and each module comprises a cascade solid-state transformer and an output end module; the cascaded solid-state transformer is formed by cascading a plurality of solid-state transformer units, and each solid-state transformer unit comprises an input stage, a transformation stage and an output stage; and each output end module comprises a plurality of output ports which are connected in parallel. The zero-sequence current can be reduced when the number of charged vehicles changes, and the problem of current imbalance caused by power change is solved; and the defect that an existing new energy vehicle charging device can only charge vehicles with single power and voltage types at present is overcome.

    本发明公开了一种应用于多类型新能源载具充电的充电装置,该装置提供若干种不同型号功率及电压输出的模块,每个模块包括级联型固态变压器及输出端模块;所述级联型固态变压器由若干个固态变压器单元级联而成,所述固态变压器单元包括输入级、变压级和输出级;所述输出端模块包括若干个并联的输出端口。本发明能够在充电车辆数目发生变化时削减零序电流,解决功率变化引起的电流不平衡问题;并且解决了现有的新能源交通工具充电装置目前只能为单一功率及电压类型的交通工具进行充电的不足。
