EPC will exhibit an innovative wireless power tabletop at 2017 Wireless Power Summit highlighting the capability of GaN-based semiconductor magnetic resonance technology to provide wireless power over a large surface area to many receiving devices such as cell phones, laptop computers, and table lamps – at the same time!
EL SEGUNDO, Calif. — September 2017 — The future of wireless power and its eventual ubiquitous adoption is dependent upon the ability of end users to place any electrical item on a surface and have it powered without having to “plug in.” It is this ability that EPC will demonstrate at the Wireless Power Summit 2017 being held in Denver, Colorado October 5th and 6th at the Embassy Suites Hotel Downtown.
The Summit will provide wireless power industry forecasts, showcase its latest technologies and give current insights into the wireless power market For more information on the Summit, visit http://www.wirelesspowersummit.com/
Wireless Power Technology, Large Surface Areas, and GaN Technology
A world with no power cords where you have the ability to place whatever you need on a single surface to charge and power is here today! The fundamental technology to achieve this “drop-and-go” power is defined by the AirFuel Alliance standard. eGaN® FETs and ICs, operating at 6.78 MHz, are featured in the amplifiers that are powering the transmit coils of the wireless power surface and in the receive circuits used in the devices placed on the surface.
eGaN technology is ideal for wireless power applications due to its ability to operate at high frequency, high voltage, and high power. The wireless power table being demonstrated at this Summit is capable of delivering a total of 165 W of power, thus enabling simultaneous powering of multiple devices.
Several eGaN products are critical to the wireless power table design. Specifically, the amplifier on transmit side of table uses the EPC9512 power amplifier. The amplifier takes advantage of the performance of the EPC8010 as the main power stage FET, the EPC2038 as the synchronous bootstrap FET and the EPC2019 is critical in the SEPIC pre-regulator. On the receive side, the EPC2019 is also used as a boost FET to accommodate the multiple power levels of the receive devices to be placed on the tabletop, which range from 5 W for cell phone charging to 25 W to power the laptop.

EPC is the leader in enhancement-mode gallium nitride based power management technology. EPC was the first to introduce enhancement-mode gallium-nitride-on-silicon (eGaN) FETs as power MOSFET replacements in applications such as DC-DC converters, wireless power transfer, envelope tracking, RF transmission, power inverters, remote imaging and sensing technology (LiDAR), and Class-D audio amplifiers with device performance many times greater than the best silicon power MOSFETs. EPC also has a growing portfolio of eGaN-based integrated circuits that provide even greater space, energy, and cost efficiency.
