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

5V Qi wireless charger for A11 Qi coils

The technologies today are rapidly advancing, the day that charging your smartphones wirelessly is here. The convenience of charging your phone without plugging a cable into it is one of the advantages of wireless charging technology. The difference between wired and wirelessly charging may be minimal but the comfort, speed, usability of it can matter in situations. The Wireless charging technology works on the principles of electromagnetic induction. The coil in the charging plate or base creates a magnetic field as current passes through. The field created will induce an electromotive force (EMF) that produces electrical current in an adjacent coil of wire without actually touching it.
