A direct current (DC) fast charger for charging a battery of an electric vehicle (EV) includes a primary circuit having seven bidirectional switches electrically linked to a primary wire of a transformer and configured to receive an alternating current (AC) voltage; and a secondary circuit comprising a plurality of diodes arranged to rectify the AC voltage into a DC voltage, electrically linked to the secondary leads of the transformer such that the DC fast charger unidirectionally converts the AC voltage received at the primary circuit into the DC voltage output by the secondary circuit.

    一种用于对电动交通工具(EV)的电池充电的直流(DC)快速充电器包括:初级电路,其具有电链接到变压器的初级导线并且配置成接收交流(AC)电压的七个双向开关;以及次级电路,其包括布置成将AC电压整流成DC电压的多个二极管,电链接到变压器的次级导线,使得DC快速充电器将在初级电路处接收的AC电压单向地转换成由次级电路输出的DC电压。
