A wireless charging control method for an electric vehicle or a wireless charging transmitter includes an inner-loop control circuit, a boost circuit, an inverter circuit, and a transmitting coil, where the inner-loop control circuit is coupled to both the boost circuit and the inverter circuit, and an input end and an output end of the inverter circuit are respectively coupled to the boost circuit and the transmitting coil, and the inner-loop control circuit is configured to obtain a first current reference signal and a sampled current signal of the transmitting coil, compare the first current reference signal with the sampled current signal to obtain an absolute value of a difference between the first current reference signal and the sampled current signal, and adjust a phase shift angle of the inverter circuit or a duty cycle of the boost circuit when the absolute value is greater than a preset deviation.
