EPC Introduces a wireless multi-mode demo system compatible with all current wireless power charging standards

The EPC9121 from Efficient Power Conversion (EPC) is a demonstration multi-mode wireless power charging kit. The purpose of this demonstration kit is to simplify the evaluation process of using eGaN FETs and ICs for multi-mode wireless power charging systems that can cut across any standard used in the receiving units.

Wireless power has arrived, but along with its emergence are two industry standards to which end products are being built: the Wireless Power Consortium (Qi) standard and the AirFuel Alliance standard. These two standards are based on two different technologies for accomplishing wireless power charging. The Qi standard, based on inductive coupling technology, uses a low-frequency (• A multi-mode source coil (transmit coil) compatible with both the AirFuel Class 2 standard and Qi (A6)/PMA standards.
• An AirFuel-compatible Category 3 AirFuel device coil (receive coil) with rectifier and dc output.
• A Wireless Power Consortium (Qi) and Power Matters Alliance (now AirFuel) compatible device coil (receive coil) with rectifier and dc output.

Thus, the EPC9121 demonstration kit contains all components needed to demonstrate and evaluate multi-standard wireless power charging. The system is priced at $907.20.
