Abstract:
Würth Elektronik eiSos (WE) has developed a system that implements inductive wireless power transfer (WPT) along with simultaneous near field communication (NFC). The system uses a new product that combines WPT and NFC with an NFC antenna wrapped around the WPT coil to form a single efficient component. This paper describes the design goals and the optimization steps required for simultaneous operation of the WPT and NFC. This investigation is done by measurement, calculation and simulation. The developed WPT/NFC system is the first published simultaneous operating system delivering up to 190 W output power at a transfer distance of 1 cm and a data rate of 106 kbit/s with an error rate of 0 %.
