The implementation of the Wireless Power Consortium’s (WPC’s) Qi standard1 brings wireless power to many different end applications.
The receiver (Rx) coil for each application may have different geometries and/or power requirements. Since the Rx coil is a key component in a successful and efficient design of a Qi-compliant Rx and there are many design options and trade-offs to consider, the designer must take a careful and methodical approach when realizing a solution.
This article is offered from Texas Instruments 3Q12 Analog Applications Journal (AAJ). The article written by Bill Johns, Applications Engineer, Tony Antonacci, System Engineer, and Kalyan Siddabattula, System Engineer provides the technical insight needed to realize a successful Rx-coil design.
