Infineon knows end-users demand more freedom of movement and higher power ratings. OEMs want smaller form factors, high efficiency levels, certified, safe products, good heat management, and low costs. Infineon knows about those challenges and how to support engineers meeting those expectations while, at the same time, still being fast in the wireless charging design development (1 W to 400 W).
Wireless power transfer is a complex process. Electromagnetic fields are used to transfer power from a transmitter to a receiver application to charge the battery. There is no more need for physical connectors and cables to transfer power, just one of many benefits of this technology.
Designers need to understand antennas and how they interact with surrounding structures. To successfully transfer power wirelessly, the power delivery must be precisely controlled. Wireless charging is not just about charging smartphones; the trend to use wireless charging for higher power applications is getting more and more traction. One great example of moving into higher power levels is a 45 W wireless charging solution from Spark Connected called "The Minotaur".
