The invention relates to the technical field of wireless charging, and discloses a wireless charging transmitter, a receiver, a charging pile, an electric vehicle and a system.The wireless charging transmitter is applied to the charging pile and comprises a first rectifying circuit, a high-frequency inverter circuit, a first resonance circuit and a transmitting coil which are sequentially connected in series; firstly, an alternating-current power supply is converted into direct current through the first rectifying circuit, secondly, the direct current is converted into high-frequency square-wave alternating current through the high-frequency inverter circuit, and then the high-frequency square-wave alternating current is converted into high-frequency sine-wave alternating current through the first resonance circuit. And finally, the transmitting coil converts the high-frequency sine wave alternating current into a sine alternating magnetic field and transmits the sine alternating magnetic field to the wireless charging receiver, so that the wireless charging receiver converts the sine alternating magnetic field into direct current and transmits the direct current to a battery of the electric vehicle, wireless charging of the electric vehicle is achieved, and the charging process is safer.
