矽元件的競爭對手悄悄走進面向Apple、Google及Tesla的半導體市場

人們用矽材料命名了“矽谷”,而矽材料現正面對全新並具有潛力的競爭對手 - 氮化鎵(GaN)材料。有說氮化鎵元件可以取得300億美元的半導體電源供應產業的市場份額。這個市場涵蓋了所有利用牆上的電源插座取得電源的產品—從Apple(AAPL)的iPhone充電器,以至Tesla(TSLA)的豪華電動汽車。

A Silicon Pioneer Plays Taps for Silicon and Power Cords

Tuesday I was fortunate enough to have a meeting with Alex Lidow, founder of chip company EPC of El Segundo, California, and something of an luminary of the chip world. Lidow came up with the “power MOSFET,” a device that went on to be the basis of billions in semiconductor sales, in 1977.

His new company, whose initials stand for “Efficient Power Conversion,” proposes replacing silicon, the original basis of the MOSFET, and one of the most prevalent types of semiconductor around, with a different material, Gallium Nitride, commonly abbreviated as GaN — or “eGaN,” as Lidow calls the company’s new, improved form of GaN.

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.

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.

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

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

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?

WiGaN: Low Cost Differential-Mode Wireless Power Class-E Amplifier Using eGaN FETs

In this installment of WiGaN, a differential-mode class-E amplifier for 6.78 MHz loosely coupled resonant wireless power applications is presented. It uses the EPC2037 eGaN® FET which has a small (0.9 mm x 0.9 mm) footprint and can be driven directly with a logic gate. The amplifier is AirFuel™ Class 2 compatible, capable of delivery up to 6.5 W load power over an impedance range of 70j Ω.

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

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.

為何氮化鎵元件比矽元件"優勝6000倍"?

宜普電源轉換公司的首席執行長Alex Lidow說矽材料是半導體的主要材料,它一直以來是電子行業背後的推動力。可是,它的性能已經到了極限。位於美國洛杉磯的宜普公司正在探究以具備更高的性能的氮化鎵(GaN)元件顛覆市場並且取得矽元件價值4000億美元(2770億英鎊)的市場份額。Alex說:「這是業界首款比矽元件的成本更低並且具備更高的性能的半導體。」

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).
