Wireless Power Transmitter Analog Front End

Nowadays, wireless power charging has become more and more common among mobile devices. Due to its widespread use, Wireless Power Consortium (WPC) created the Qi standard. This Qi interface standard is created for inductive electrical power transfer over distances of up to 4cm. The Qi system is used by placing the mobile device on top of the power transmission pad. It charges the mobile device via resonant inductive coupling. This project is a design of a wireless power transmitter analog front end. It contains all of the analog components required to implement a WPC compliant 5-V transmitter. Read more
