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.

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.

Driving GaN Into The Fast Lane

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.”

Fact: GaN technology a more efficient semiconductor than silicon for the Data Center power conversion process.

1894

Written by:

Over the past few decades, metal oxide semiconductor field effect transistors (MOSFETs) have largely been the staple source for power supplies. MOSFETs are silicon-made devices controlled by voltage that manipulate the supply’s electricity that come in the form of little black squares. They’ve become very prevalent throughout the semiconductor industry, but might see their mainstream status begin to wither.

Emerging the scene is gallium nitride (GaN), devices that are expected to become smaller, cheaper, and more efficient in the long run. Silicon-based semiconductors had voltage coming into a data center at 48V go through multiple instances of power conversion before finally reaching its on-board components, during which the voltage would shed energy at each of these phases. According to Dr. Alex Lidow, chief executive of the Efficient Power Conversion (EPC) Corporation, Silicon wasn’t fast enough to reach 1V all the way from 48V.

“So what we (as an industry) did was create a whole bunch of very expensive power supplies that get you from 48V to 12V, and another set of power supplies that get you from 12V to 1V,” says Lidow.  “And with gallium nitride, since it’s so damn fast, you can get rid of the whole intermediate bus and go directly from 48V to 1V.”
