What`s coming next
As wireless power becomes more integral to our mobile and connected lives, Infineon and Spark Connected continue to drive next generation technologies and standards that allow readily available charging without the limitation of wires. What started out with phones will quickly be taken over by applications such as tablets, laptops, handheld gaming, medical devices, automotive, infrastructure and industry 4.0. Given the breadth and different types of wireless power technologies in their arsenal, Infineon and Spark Connected are in a strong position to provide the solutions that allow users to cut that last cord.
In the future, some applications will require very high-power levels or higher frequencies for specific user charging experiences. These applications will benefit from solutions that have improved power/performance capability, such as GaN. In many of these situations, efficiency is the critical metric, and GaN e-mode HEMTs provide a high-power charging solution with a manageable thermal impact. Because of its better high frequency performance, GaN also provides an optimal solution for class E amplifiers in resonant wireless charging.
Infineon Technologies and Spark Connected will present their wireless power solutions at the Embedded World trade fair in Nuremberg, Germany (February 25-27, hall 3A). Further information is available at www.infineon.com/embeddedworld and www.infineon.com/mwc.
