NuCurrent’s wireless power experts cover common NFC Charging questions, including:
Designing a NFC WLC system is all about transferring power efficiently while maintaining communications fidelity. In other words, creating a balance between low power loss and high data integrity.
NFC WLC systems rely on techniques from both NFC data and wireless power to ensure the most efficient power transfer while maintaining the necessary bandwidth to support high speeds of data transfer.
The top-right graph shows a high-Q system (pink line) that is capable of efficiently transferring power, while the green line shows a low-Q antenna that allows for communication signal integrity. The key is to find the balance for the customer’s system.
The lower right graph shows how a high-Q antenna integrates into a system using novel coupling techniques to ensure bandwidth requirements are met. This allows designers the flexibility to trade off performance characteristics to hit specifications.
Qi and NFC WLC both have strengths and limitations.
The chart to the right explores important design considerations for product developers.
When exploring your options, consider criteria such as form factor, user experience, power received and data capabilities.
A NFC WLC system is similar to a traditional wireless power system, with the addition of NFC control. NFC blocks provide the primary function of transferring data, while the remaining foundational blocks function similarly to a Qi-based system. The main difference: As data speeds are increased, power levels must be considered as it will affect the integrity of the data.
The chart to the right provides an overview on the structure of a NFC WLC system.
Get started with understanding the global specification by going directly to the consortium that created it.
NXP Semiconductors, an NFC Forum co-founder, supplies a majority of the market with NFC-enabled hardware. Browse their hardware options.
As an NXP Gold Partner, NuCurrent is advancing the standard making higher power levels and data rates possible.
The NFC Forum WLC standard currently specifies wireless power transmitted at 1W and data throughput at 106 Kbps.
