A wireless charging transmitting apparatus and method and a wireless charging system are provided. The transmitting apparatus includes a compensation circuit, an inverter circuit, a transmitting coil, an impedance adjustment circuit, and a controller. The impedance adjustment circuit includes a leading-bridge-arm impedance adjustment circuit and a lagging-bridge-arm impedance adjustment circuit, and the leading-bridge-arm impedance adjustment circuit and the lagging-bridge-arm impedance adjustment circuit each include an inductive branch, where the inductive branch includes at least one controllable inductive branch, and each controllable inductive branch includes at least one inductor and at least one switch. The controller controls the switches in the controllable inductive branches to be turned on or off, to adjust values of inductive currents injected into a leading bridge arm and a lagging bridge arm through the impedance adjustment circuit.
