Development Boards Make Evaluating eGaN FETs Simple

Long talked about, wide bandgap gallium nitride-on-silicon (GaN-on-Si) transistors are now commercially available. They are being touted for replacing silicon-based MOSFETs, which are turning out to be inefficient for many high-performance power supply designs. Recently, several suppliers of GaN-on-Si-based HEMTs and FETs have emerged in the marketplace, among them Efficient Power Conversion (EPC). To expedite the evaluation of eGAN FETs for power supply designs transitioning from silicon MOSFETs to eGaN FETs, EPC has released several development boards in the last few years.

功率氮化镓市场于2016年至2020年的复合年均增长率将达80%

氮化镓器件于2020年的销售额预期可达差不多6亿美元并大约需要制造58万片6英寸晶圆。氮化镓器件的市场将于2016年起发展迅猛,至2020年的複合年均增长率达80%,这个预期是基于EV/HEV预计从2018至2019年开始采纳氮化镓得出。于2015年至2018年,电源供电/功率因数校正将成为主要市场并将最后占氮化镓器件销售总额 50%,届时氮化镓器件于车用市场将急起直追。

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正式登场,传统功率器件将被替代

MOSFET、IGBT可以休矣,即将成为过去,在这个250亿美元的市场取而代之的将是GaN功率器件——这是EPC首席执行官Alex Lidow日前在接受EDN China专访时的说法。Lidow博士之前在IR担任了12年CEO,在2007年他创立了宜普电源转换公司(Efficient Power Conversion Corporation,EPC),他在斯坦福大学的博士论文就是关于HEXFET功率MOSFET的,是相关专利的发明者之一。在HEXFET专利过期之前,相关版税已超过9亿美元。
