Abstract: A wireless power transmitter with protection against damage to Near Field Communication (NFC) devices within range includes a DC/DC converter, a power transmitting controller, an MCU, a switch having two switching ports, a matching unit having two capacitors connected in parallel, and a coil. The DC/DC converter converts a supplied direct current to another level and outputs the direct current before the wireless power transmitter is activated. The converted DC causes one switch port to be conductive, thereby the first capacitor and the coil cooperatively generate a first resonant frequency equal to NFC operating frequency. The power transmitting controller transmits a control signal to the coil which can determine the presence of an NFC device within the wireless charging field. The power transmitting controller is turned off if an NFC device is within the field.
