Developing a multi-channel wireless inductive charger

This paper will outline the basics of the technology, and how we can accomplish a multiple pad charging device using a single, low-cost Texas Instruments C2000 Piccolo microcontroller. The advantage of a microcontroller-based solution can be realized through the flexibility of the both the power stage design and communications protocols that are enabled, as well as the number of charging pads that can be controlled through a single device.
