Magnetic resonance technology is the key to ubiquitous implementation – enabling large surface area transmission, spatial freedom for placement of receiving devices, and the ability to power multiple devices simultaneously.
The popularity of highly resonant wireless power transfer is increasing rapidly, particularly for applications targeting large power transmitting surface areas, with the capability to place receiving devices anywhere on the surface, and the ability to simultaneously power (or charge) multiple devices placed on the surface. The end applications are varied and evolving quickly from cell phone charging to powering handheld tablets and laptop computers. Delivering up to 33 W supports all of these applications.
At the members meeting attendees learned about next-generation wireless power technology – including current and near-future deployments – and heard from leaders such as Alex Lidow from the semiconductor space as well as consumer electronics, robotics, AR/VR, and healthcare industries, to name a few.
AirFuel Alliance’s mission is to bring a diverse base of interoperable products to the global market that deliver the best wireless charging experience for consumers. The organization membership is made up of leading technology and consumer electronics companies. Its board of directors includes representatives from Dell, Duracell, Energous, EPC, ONSemiconductor, PowerSphyr, Qualcomm, Samsung Electronics, Starbucks and WiTricity.
EPC CEO, Alex Lidow sits down with Spirit Electronics CEO, Marti McCurdi to discuss how EPC has worked with industry leaders over the past decade to test high-reliability GaN products for military and space applications.
The Growing Ecosystem for eGaN FET Power Conversion
In recent years, GaN-based power conversion has increased in popularity due to the inherent benefits of eGaN FETs over conventional Si transistors. Migrating a converter design from Si to GaN offers many system-level improvements, which require consideration of all the components in that system. This trend has subsequently spurred a growth in te ecosystem of power electronics that support GaN-based designs.
Cloud servers, advanced gaming systems, artificial intelligence, cryptocurrency mining, and automotive electronics are all converging rapidly on 48 Volts as the new standard bus voltage. 48 V has the advantage of not requiring isolation and is therefore simpler, smaller, more efficient, and lower cost than other power conversion architectures. In every case, the relatively new GaN transistors and integrated circuits have demonstrated the ability to convert to-and-from 48 Volts with higher efficiency, and smaller size. GaN is also able to significantly reduce costs. In this seminar we will show the various applications and topologies used in these markets and show the steps taken to convince conservative design engineers that the best solution involves GaN.
Ask EPC’s chief executive, Alex Lidow, what the future holds for his GaN power device business, and automotive certification features prominently.
Recently delivering AEC Q101-qualified 80 V discrete transistors for LiDAR, 48V power distribution systems and other applications, the company’s latest enhancement-mode FETs deliver higher switching frequencies and efficiencies than silicon MOSFETs, in a smaller footprint. And this is just the beginning.
“We have more transistors as well as integrated circuits designed for LiDAR [sensors] and are proceeding with automotive certification here,” highlights Lidow. “LiDAR is under intense cost and performance pressure so integrating components and improving performance while lowering the cost is a big deal.”
