This application discloses a wireless charging transmitter, a wireless charging receiver, and a wireless charging system. The transmitter includes: an output end of an inverter is connected to a transmitter compensation network; an output end of the transmitter LCC network is connected to a transmit coil; and a switch circuit is connected to the transmitter LCC network. The receiver includes a receiver LCC network. When a real part of a first output impedance of the inverter is greater than a real part of a second output impedance of the inverter, a transmitter controller controls the switch circuit to act, so that the wireless charging system works in a double-sided LCC network. When the real part of the first output impedance is less than or equal to the real part of the second output impedance, the transmitter controller controls the switch circuit to act, so that the wireless charging system works in a single-sided LCC network. The first output impedance is an output impedance of the inverter when the wireless charging system works in the double-sided LCC network, and the second output impedance is an output impedance of the inverter when the wireless charging system works in the single-sided LCC network. A wide coupling range is achieved, and charging efficiency is high for different vehicle types.
