eGaN vs. Silicon - Comparing Dead-time Losses for eGaN FETs and Silicon MOSFETs in Synchronous Rectifiers

eGaN vs. Silicon - Comparing Dead-time Losses for eGaN FETs and Silicon MOSFETs in Synchronous Rectifiers
There have been several comparisons of eGaN FETs with silicon MOSFETs in a variety of applications, including hard-switched, soft-switched, and high-frequency power conversion. These studies have shown that eGaN FETs have large efficiency and power density advantages over silicon MOSFETs. Here we’ll focus on the use of eGaN FETs in synchronous rectifier (SR) applications and the importance of dead-time management. We show that eGaN FETs can dramatically reduce loss due to dead-time in synchronous rectifiers above and beyond the benefits of low RDS(on)and charge. Power Systems ... Read more

Raytheon's work on gallium nitride semiconductors could have a reach beyond radars

Raytheon's work on gallium nitride semiconductors could have a reach beyond radars
ANDOVER, Mass.—At the front door of Raytheon's Integrated Air Defense Center, there's a reminder of how big microwave electronics used to be—the original microwave oven. The now ever-present kitchen device was invented after a Raytheon engineer discovered his candy bar melted while he was standing near a magnetron used in a radar system the company was developing. Nearly the size of a refrigerator, the original microwave looks like it would cook a whole lot more than whatever was put within its metal grate, which was meant to contain the microwaves from its magnetron.

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. Wired Magazine Emma Bryce March 31, 2016 Read article Read more

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). TI E2E ... Read more

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.
