Wireless Power Transfer (WPT)

Wireless Power Transfer takes several different forms, but the most common today is the use of magnetic resonance to provide a safe, flexible, and convenient option to electrically charge products. While some manufacturers are beginning to look at using higher frequencies for WPT, this article focuses on the devices that operate less than 1 MHz.

The radio frequency function of these wireless charging devices is the wireless transmission of energy between a wireless power source and a receiver. Because these devices are used in close contact with humans, product safety considerations are imperative. These devices must adhere to FCC guidelines for RF exposure. EMC compliance for wireless charging devices is also required due to the transmission of energy during use.

This paper highlights some of the technology, use cases and regulatory challenges for WPT and where this technology may lead us in the future. Download the paper to learn more.
