The invention discloses direct-current charging pile equipment. The equipment comprises a main control board system, a direct-current charging power supply system and a plurality of charging piles, wherein the direct-current charging power supply system comprises a double-winding transformer module, an AC/DC rectifier module, a direct-current bus and a plurality of direct-current charging output modules connected to the direct-current bus in parallel; the AC/DC rectifier module is a 12-pulse rectifier, and an eleventh harmonic filter is arranged between an input end of the double-winding transformer module and an AC input end. By configuring the eleventh harmonic filter, low-order harmonics generated by 12-pulse rectification are suppressed, 13-th harmonics or below can be filtered out, resonance is not easy to generate, and the reliability and durability are higher; the secondary winding voltage of the double-winding transformer module is AC500V, the rectified voltage does not exceed520V-850V, and the input voltage range of the charging pile is met.
本发明公开了一种直流充电桩设备,包括主控制板系统、直流充电电源系统以及多个充电桩,所述直流充电电源系统包括依次连接的双绕组变压器模块、AC/DC整流器模块、直流母线以及并联在所述直流母线上的多个直流充电输出模块;所述AC/DC整流器模块为12脉冲整流器,所述所述双绕组变压器模块的输入端与所述交流输入端之间还设有11次谐波滤波器。通过配置11次谐波滤波器,抑制12脉冲整流产生的低次谐波,可以滤除13次以下谐波,不易产生谐振,并且可靠性、耐用性更高;双绕组变压器模块副边绕组电压为AC500V,整流后的电压不会超过520V~850V之间,满足充电桩的输入电压范围。
