Efficient Power Conversion Corporation (EPC) today announces the availability of a complete demonstration multi-mode wireless power charging kit, the EPC9121. The purpose of this demonstration kit is to simplify the evaluation process of using eGaN FETs and ICs for highly efficient multi-mode wireless power charging systems that can cut across any standard used in the receiving units. Two Standards, One Solution 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
Two Standards, One Solution 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 upon two different technologies for accomplishing wireless power charging. The Qi standard, based on inductive coupling technology, uses a low frequency (<300 kHz) approach, whereas the AirFuel standard uses a magnetic resonant technology and has both low frequency (100 kHz through 315 kHz) and high frequency (6.78 MHz) requirements. Thus the need for a multi-mode solution, one with a single transmitter that can power a receiver built using either standard. The EPC9121 is the first implementation of a single amplifier multi-mode solution. GaN enables high efficiency for both low and
