Abstract

Provided are a transformer and a power supply board including the transformer, the transformer includes: a power supply circuit, wherein the power supply circuit includes a power supply antenna and the power supply circuit is configured to transmit electric power through the power supply antenna; and a power receiving circuit, wherein the power receiving circuit includes a power receiving antenna and the power receiving circuit is configured to receive the electric power transmitted by the power supply antenna through the power receiving antenna. The transformer uses the principle of resonance wireless charging so as to improve the working frequency of the transformer, decrease the volume and weight of the transformer, save a magnetic core, and decrease or eliminate the magnetic core loss.
