EPC to demo large surface area wireless power
GaN-based wirless power 'tabletop' technology will be on show at the Wireless Power Summit 2017 in Denver, Colorado
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!
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
EPC says its 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 165W 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.
