The invention discloses a wireless charging pile, which comprises a shell, and is characterized in that the shell is internally provided with a conversion unit used for converting an externally input alternating current into a direct current; the inversion unit is connected with the conversion unit, and the inversion unit is used for inverting the direct current into high-frequency alternating current; and the wireless transmitting unit is connected with the inversion unit, and the wireless transmitting unit is used for transmitting the high-frequency alternating current to a wireless receiving end of the vehicle through a transmitting coil. According to the wireless charging pile, the power supply unit PSU and the wireless charging transmitting end GA in a traditional wireless charging pile are integrally designed, a high-frequency litz wire between the power supply unit PSU and the wireless charging transmitting end GA is omitted, namely, the conversion unit, the inversion unit and the wireless transmitting unit are integrally designed in the same shell, so that the size of the wireless charging pile can be reduced, and the wireless charging pile is convenient to use. The space utilization rate is improved, the production cost is reduced, and strong electromagnetic radiation cannot be generated.
本发明公开了一种无线充电桩,包括壳体,所述壳体内安装有:转换单元,所述转换单元用于将外部输入的交流电转换为直流电;逆变单元,该逆变单元与转换单元连接,所述逆变单元用于将直流电逆变为高频交流电;无线发射单元,该无线发射单元与逆变单元连接,所述无线发射单元用于将高频交流电通过发射线圈传递至车辆的无线接收端。本发明将传统无线充电桩内的电源供应单元PSU和无线充电发射端GA集成设计,取消了电源供应单元PSU和无线充电发射端GA之间的高频利兹线,即将转换单元、逆变单元和无线发射单元集成设计在同一个壳体内,这样不仅能减小无线充电桩的体积,提高了空间利用率,还降低了生产成本,还不会产生很强的电磁辐射。
