Title: TRANSFORMER AND POWER SUPPLY BOARD
Abstract:
Provided are a transformer (10) and a power supply board comprising the transformer (10). The transformer (10) comprises: a power supply circuit (100), which comprises a power supply antenna (110) and is configured to transmit power through the power supply antenna (110); and a power receiving circuit (200), which comprises a power receiving antenna (210) and is configured to receive the power transmitted by the power supply antenna (110) through the power receiving antenna (210). By using the principle of resonant wireless charging, the operating frequency of the transformer (10) is improved, the volume and weight of the transformer (10) are reduced, the magnetic core is saved, and the core loss is reduced or eliminated.
