摘要： Systems and methods are provided for wireless power transfer in a vehicle. A wireless power transfer system can include a high-frequency alternating current (HFAC) inverter electrically coupled to the power source and a transmitter to wirelessly transmit a HFAC power signal to at least one device of a vehicle, such as sensors (e.g., LiDAR, GPS etc.) and cameras. The HFAC power signal provides wireless power and a data signal to the at least one device of a vehicle. The wireless power transfer system can eliminate the need for cabling and wires to provide power to the device. Wireless power transfer can include use or a data modulation circuit and a pulse current source to inject a pulse current to the HFAC power signal as superimposed data. System configurations can power a plurality of devices. Systems can includes a plurality of HFAC inverters and transmitters to power multiple sets of devices.
