jjPLUS and EPC, both members of the AirFuel Alliance, to show how large area wireless power surfaces can be designed following the most advanced AirFuel™ Resonant standard. Go for a wirelessly powered home and office!

EL SEGUNDO, Calif. — June 2018 — jjPLUS Corporation, a design manufacturer of advanced wireless communication and wireless power embedded solution company, will demonstrate the next-generation magnetic resonance wireless power transfer (WPT) technology at InnoVEX 2018 in Taipei. Joining jjPLUS will be its technology partner − Efficient Power Conversion Corporation (EPC). The demonstration units will be located in TWTC Hall 3, booth no. G0309a on June 6 – 8. Both jjPLUS and EPC participated in the AirFuel working committees and in the AirFuel Developers Forum in March 2018.

Wireless power, the ability to deliver electricity to gadgets without plugging those gadgets into a cable, is a hotbed of innovation at the moment. The dominant standard, called “Qi,” is ever under attack from other efforts.

This week saw interesting developments from Energous (WATT), which aims to transfer power via radio frequency transceivers, with limited results so far, and some controversy about its business.

There are other contenders. On Wednesday in Las Vegas, during the Consumer Electronics Show, I met with Alex Lidow, who is founder of a privately held chip company EPC of El Segundo, California.

To ensure widespread adoption, wireless power systems need to move beyond small charging pads and become active power sources over large surface areas. For magnetic resonant systems, this demands fundamental changes in coil technology, system architecture, and power amplifiers. Gallium nitride based amplifiers have proven capable of delivering 60 W with greater than 90 percent efficiency into the transmit coil over a wide load range.
