Abstract

Disclosed are a power matching method and apparatus for wireless charging, and a wireless charging apparatus. The method includes receiving first sensing information sensed from a transmitting coil of the wireless transmitter, wherein the transmitting coil includes at least one of a capacitor assembly with adjustable capacitance and an inductor assembly with adjustable inductance; detecting whether resonant frequency has changed according to the first sensing information; and adjusting at least one of capacitance of the capacitor assembly in the transmitting coil of the wireless transmitter and inductance of the inductor assembly in the transmitting coil in response to the resonant frequency changing to make transmitting power of the wireless transmitter be matched with receiving power of a wireless receiver in the wireless charging system, wherein the first sensing information comprises at least one of a first sensing voltage value and a first sensing current value.
