硅基氮化镓场效应晶体管促进全新应用的出现

作者:Ashok Bindra
杂志:How2Power Today (2012年12月刊)

在过去的数年间虽然有很多讨论关于基于氮化镓的功率晶体管可以替代普遍使用的硅MOSFET器件,但硅基氮化镓的功率场效应晶体管可能需要较长的时间才可以在电源转换领域成为主流器件。目前数个全新应用的出现将有望实现氮化镓技术所提供的优势。除了具备商用及高可靠性的条件,氮化镓器件的独有特性正在促进全新应用的出现。

GaN power market to rise to $10 million in 2012, says Yole

Written by Peter Clarke - 3/7/2012 2:20 PM EST

LONDON - The market for power devices implemented in gallium nitride was less than $2.5 million in 2011, according to market research firm Yole Developpement (Lyon, France). However, there is a great deal of R&D activity and Yole sees the power GaN market growing to nearly $0 million in 2012 and $500 million in 2016.

Gallium nitride based devices set to bring substantial boost to power efficiency

Gallium nitride has long been known to have useful properties when it comes to electronic components. Even so, its application has largely been confined to more exotic areas of the industry, particularly rf transistors.

But GaN is beginning to find application in what could be considered the mainstream, with some of its proponents suggesting its arrival could mark the beginning of the end for the traditional power mosfet.

GaN and SiC: on track for speed and efficiency

Wide-bandgap materials, such as GaN and SiC, are enabling a new generation of power switching devices that switch faster and with fewer losses than the venerable silicon MOSFET, resulting in smaller, more efficient power supplies.

专用驱动器可发挥出增强型GaN FET的最佳性能 2011年6月28日13:38 发布

众所周知,宜普电源转换公司(EPC)推出商用化增强型硅基氮化镓场效应晶体管(宜普称之为eGaN FET)产品已经超过一年多时间了。目前宜普公司正在与合作伙伴一起实现eGaN FET的专用驱动器,使其可以工作在更高电压、更低栅极电荷条件下,仍具更低的RDS(ON),以及没有反向恢复损耗(QRR)——所有这些特性都在比硅产品更小的裸片面积上实现。相比硅MOSFET,eGaN FET实际上可以显著提升品质因数(FOM)。

氮化镓功率晶体管之基础

我们对功率半导体最基本的要求是性能、可靠性、管控性及成本效益。它的高频率性能,可切合稳压器系统于体积及瞬态响应方面的需要而具更高价值,并为D类功率放大器提供高保真度。一个新器件结构如果不高效、不可靠的话,根本不可能商品化。市场上有很多新结构及原料可选择,但是接受度有限。不过,现在有氮化镓(Gallium Nitride/GaN)增强型功率管控器件问世,具有高导电性、极快开关、硅器件之成本结构及基本操作模式等优异性能,其代表就是宜普公司的新产品。

High Step-Down Ratio Buck Converters With eGaN Devices

The intermediate bus architecture (IBA) is currently the most popular power system architecture in computing and telecommunications equipment. It typically consists of a +48 V system power distribution bus that feeds on-board bus converters, which in turn supply power to nonisolated, dc-dc converters. These nonisolated converters generate the low supply voltages required to power the various logic circuits. Because of their proximity to the circuits they power, these converters are commonly referred to as point-of-load converters (POLs).
