一位科学家的自述:曾为世界节省15%的电量,如今找到硅的替代物

一位科学家的自述:曾为世界节省15%的电量,如今找到硅的替代物

这位在40年前成为博士的科学家曾为世界节省了15%电量,如今他正继续自己的创新之旅,为人类找到了硅的全新替代材料。

我父亲常常教导我:一个人的真正价值,是通过他对社会所作出的贡献来衡量的。1975年我进入研究生院学习,那时我的兴趣在半导体领域,并且认为我对社会最大的贡献,就是找到可以替代硅的半导体材料。我的研究生毕业课题从围绕砷化镓展开,但是直到在1977年获得博士学位后,我才发现,作为一种半导体材料,砷化镓受其基本材料特性所影响,它的应用前景非常有限,于是我转而专注于研究如何制造出更好的硅基器件。

GaN FETs Drive Fidelity and Efficiency in Class-D Audio Amplifiers

GaN FETs Drive Fidelity and Efficiency in Class-D Audio Amplifiers

With the current maturity of Class-D audio amplifier architectures, amplifier fidelity and efficiency limitations are primarily at the device level. Silicon MOSFETs have been evolving for almost forty years, and their progress towards a perfect switch has slowed dramatically. There are some fundamental characteristics of MOSFETs that degrade sound quality and efficiency. In 2010, the enhancement mode Gallium nitride (GaN) power FET was introduced by Efficient Power Conversion (EPC), providing a large step towards the perfect switch.

Rompower Announces The AC/DC Laptop Power Adaptor Technology Capable of 94% Efficiency, 20 W/in3 Power Density in an Incredibly Small Package

Rompower Announces The AC/DC Laptop Power Adaptor Technology Capable of 94% Efficiency, 20 W/in3 Power Density in an Incredibly Small Package

Taking advantage of the high performance of eGaN® FETs, Rompower Energy Systems has announced a reference design for a tiny, 65 W, 94% efficient AC/DC power adaptor for laptops and other mobile devices.

TUCSON, Az. – June 2017 – Rompower Energy Systems, an internationally recognized research and development company in the field of power conversion, announces the availability of technology for an extremely small, highly efficient AC/DC power adapter. In the quest for higher power density, the efficiency of the adapter is critical in order to decrease the heat dissipation. The reference design is measuring just 3.19 cubic inches in size, this adapter provides 65 W of power at greater than 94% efficiency over the entire input voltage range (90 Vac – 264 Vac).  The adapter has a power density of 20 W/in3. This high efficiency means that the device runs cooler than standard AC/DC adapters.
