The invention aims to provide a direct-current charging pile system. The direct-current charging pile system comprises a voltage source V1, switching tubes Q1-Q8, anti-parallel diodes D1-D8, an inductor L and an isolation transformer T, wherein i1 represents the current flow direction of the primary side of the converter, and i2 represents the current flow direction of the secondary side of the converter; the points A, B, C and D are connecting points of the voltage sensor, the points A and B are used for measuring the primary side voltage of the transformer, and the points C and D are used for measuring the secondary side voltage of the transformer. According to the invention, high-frequency, high-efficiency, high-power-density and energy bidirectional flow of the charging pile can be realized.

    本发明的目的是提供一种直流充电桩系统,包括:电压源V1、开关管Q1‑Q8、为反并联二极管D1‑D8、L为电感和隔离变压器T;其中,i1表示变换器初级侧电流流向,i2表示变换器次级侧电流流向;A、B、C、D点为电压传感器的连接点,其中,A、B点是测量变压器原边电压,C、D点测量变压器副边电压。本发明可以实现充电桩的高频、高效、高功率密度和能量的双向流动。
