Intel Ceases Work On Wireless Charging

Intel Ceases Work On Wireless Charging

For the last three years, Intel has been stoking demand for PCs ahead of the next big buying cycle with the promise that new machines will be totally wireless. “We carry around a lot of wires,” Kirk Skaugen, Intel’s senior PC exec said at Computex Taipei 2015. “We carry about six cables each for our phones, our tablets and our PCs. We want to get rid of all those cables.”

Improving Thermal Performance with Chip-Scale Packaged Gallium Nitride Transistors

Improving Thermal Performance with Chip-Scale Packaged Gallium Nitride Transistors

With power converters demanding higher power density, transistors must be accommodated in an ever decreasing board space. Beyond gallium nitride based power transistors’ ability to improve electrical efficiency, they must also be more thermally efficient. This article evaluates the thermal performance of chip-scale packaged eGaN® FETs and compares their in-circuit electrical and thermal performance with state-of-the-art silicon MOSFETs.

5 Industries That Are Actually Ripe for Disruption

5 Industries That Are Actually Ripe for Disruption

The number one barrier to improving every electronic product – from smart wearables and laptops to handheld tools and electric cars – is battery technology. The current state-of-the-art in rechargeable batteries, Lithium Ion, has been around for 25 years. As tech goes, that’s pretty old. It’s time for something new, don’t you think?

eGaN Technology Reliability and Physics of Failure - Examining eGaN Field Reliability

eGaN Technology Reliability and Physics of Failure - Examining eGaN Field Reliability

Efficient Power Conversion (EPC) Corporation’s enhancement-mode gallium nitride (eGaN®) FETs and integrated circuits (ICs) are finding their way into many end user applications such as LIDAR, wireless charging, DC-DC conversion, RF base station transmission, satellite systems, and audio amplifiers.

Field reliability is the ultimate metric that corroborates the quality level of eGaN® FETs and ICs that have been deployed in customer applications. In our first installment we provided an overview of eGaN FET field reliability which included 6 years of volume production shipment, and greater than 17 billion total device hours recorded. A subsequent calculated Failure In Time (FIT – failures in 109 hours) of approximately 0.24 FITs shows excellent field reliability performance to date.

Data center next generation power supply solutions for improved efficiency

Data center next generation power supply solutions for improved efficiency

Claude Shannon started it all when he wrote “A Mathematical Theory of Communication” in 1948 in which he reduced the communication of information to 1s and 0s, essentially binary digits. That theory led to the ability to transmit data without error in the noise-filled environment of the real world. Shannon would have been 100 years old on April 30, 2016.

What GaN circuits can do for wireless charging

What GaN circuits can do for wireless charging

In this short video, EPC's Alex Lidow explains why GaN FETs may make it possible to wirelessly charge a variety of vehicles, including flying drones. Wireless charging circuits employing GaN FETs work at 13.56 MHz, a switching frequency difficult to reach with ordinary silicon FETs. The GaN transistors used are also five to ten times smaller than silicon devices able to handle the same power levels.

Why GaN circuits make better Lidar

Why GaN circuits make better Lidar

In this short video, EPC's Alex Lidow explains why GaN FETs can comprise circuits able to deliver Lidar resolutions down to a couple inches. Conventional silicon FETs performing the same tasks would be able to resolve images only down to a few feet. The secret is in the super-fast rise and fall times made possible by the GaN FETs.

Why gallium nitride is '6,000 times better' than silicon

Why gallium nitride is '6,000 times better' than silicon

Silicon -- the core ingredient in semiconductors and the driving force behind the electronics industry -- is reaching its limit, says Alex Lidow, CEO of Efficient Power Conversion Corporation. His Los Angeles-based company is investigating the capacity of gallium nitride (GaN) to disrupt the $400 billion (£277bn) silicon industry with its improved powers of semiconducting. "This is the first 
time that there is a semiconductor that is both lower cost and has a higher performance than silicon," Lidow says.

Highlights from APEC 2016 – GaN, 48V POL, wireless charging and more!

Highlights from APEC 2016 – GaN, 48V POL, wireless charging and more!

Emerging applications such as 48V-to-point-of-load (POL), wireless power and USB Type-C had a lot of interest. Google joined the Open Compute Project a few weeks ago and proposed a computer server-rack architecture based on a 48V power-distribution bus to improve overall system efficiency. While the 48V bus has been around for a long time, the push (and challenge) is for high-efficiency 48V-to-POL voltage regulators. EPC showcased TI’s 48V-to-1V EVM which uses the LMG5200 GaN module (driver and FETs), announced at APEC last year, and a new TI analog controller (TPS53632G).

APEC 2016: An Engineer's Perspective on a Power Conference

APEC 2016: An Engineer's Perspective on a Power Conference

You might have seen some behind-the-scenes tweets from the life of the ECN editor (and News Director) and while a picture is worth a thousand words, sometimes an engineer's perspective on a conference is worth a little more.

With that in mind, I reached out to some APEC engineers and attendees to get the lowdown on this year's Applied Power Electronics Conference in Long Beach, CA. We talked about how the show compared to last year, the biggest trends, and how APEC went for their companies.

Reflections On APEC 2016: GaN’s Momentum, More Magnetics And An Inspiring Plenary

Reflections On APEC 2016: GaN’s Momentum, More Magnetics And An Inspiring Plenary

At this year’s APEC 2016, news about GaN power technology was probably more dominant than at any time in the past. Real product demos using GaN, new product and technology announcements, attention to GaN in the plenary, and other discussions all reinforced the impression that GaN power devices have arrived and the technology is making inroads in the marketplace. One of the tell-tale signs is a slight shift in the discussions, away from what the devices can do to what else is needed to support the design-in of GaN power transistors.

15 MHz Half-Bridge Development Boards Use EPC's eGaN FETs and High Frequency Synchronous Bootstrap Topology

15 MHz Half-Bridge Development Boards Use EPC's eGaN FETs and High Frequency Synchronous Bootstrap Topology

EPC’s new development boards can be configured as either a buck converter or a ZVS class-D amplifier, demonstrating reduced losses at high frequency using an eGaN FET synchronous bootstrap augmented gate drive.

EL SEGUNDO, Calif.— March 2016 — Efficient Power Conversion Corporation (EPC) Introduces the EPC9066, EPC9067, and EPC9068 development boards, which are configurable to a buck converter or as a ZVS class-D amplifier. These boards provide an easy-to-use way for power systems designers to evaluate the exceptional performance of gallium nitride transistors, enabling the designers to get their products into volume production quickly. All three boards feature a zero reverse recovery (QRR) synchronous bootstrap rectifier augmented gate driver to increase efficiency at high frequency operation, up to 15 MHz. The boards can produce a maximum output of 2.7 A in the buck and ZVS class-D amplifier configurations. Loss reduction is realized across the entire current range.
