Development platform explores inductive resonant power transfer

It offers patented high-frequency wireless charging technology, delivering up to 300W of power. It also offers multi-device charging and extends the freedom of device placement which opens up new product applications.

For product developers interested in wireless charging, the platform brings new functionality and benefits via inductive resonant charging, compared to RF-based methods and inductive-based charging methods like Qi.

“There are a great number of product categories that aren’t well-served by RF and inductive charging,” said NuCurrent’s CEO, Jacob Babcock.

“NuEva HF delivers power levels about 1,000X higher than RF and it provides positioning flexibility about 100X that of Qi, plus it offers the ability to charge multiple devices simultaneously,” he says.  

The NuEva HF platform operates at 6.78MHz, the same frequency as the standard developed by the AirFuel Alliance. This high-frequency method of power transfer delivers multi-device charging from a single transmitter, greater spatial freedom and positioning flexibility, high system efficiencies and uniform charging zones and power up to 300W. Developers can use the platform to explore inductive resonant power transfer’s viability for applications as wide ranging as gaming and robotics to personal transportation and medical devices, says the company.

It offers patented and proprietary technologies, including surface “repeater” technology which extends charging surface areas using inexpensive passive electronics driven from a single power source. There is also multi-layer, multi-turn (MLMT) antennae that increase efficiencies and lower thermals, methods for cost-effective EMI mitigation, in-band communications for reduced cost system (compared to Bluetooth) and also options for power transfer through a variety of materials (for example metal or tissue).
