Zusammenfassung:	Embodiments of the present disclosure relate to a power regulation method, apparatus, and device for NFC communication and NFC charging. The apparatus includes: an NFC power converter, an NFC coil, an NFC circuit, a controller, and a power regulator. The NFC power converter is configured to connect to a direct-current power supply and generate a high-frequency alternating-current output. The NFC coil is configured to generate/receive an NFC high-frequency magnetic field and transmit/receive NFC power or an NFC signal. The NFC circuit is connected to the NFC power converter and is configured to transmit/receive the high-frequency alternating-current output. The controller is configured to generate different power control signals based on different operating modes of an NFC apparatus. The power regulator is configured to connect one end of the power regulator to the direct-current power supply and the other end of the power regulator to the NFC circuit, and is configured to regulate, based on the different power control signals, at least one of a magnitude and a phase of power output to the NFC circuit. Active power/reactive power is injected according to an operating state of the NFC apparatus, to improve performance of wireless communication and/or wireless charging.
