New converter topologies and power transistors promise to reduce the size and boost the efficiency of supplies that will run next-generation Artificial Intelligence (AI) platforms. In all the topologies with 48 V_IN, the highest efficiency comes with using GaN devices. This is due to their lower capacitance and smaller size. With recent pricing declines in GaN power transistors, the cost comparison with silicon-based converters now strongly favors GaN in all the leading-edge solutions.

Developers are hard at work on the machine learning necessary for safer and more-autonomous vehicles. But all the AI in the world won’t be enough if the car relies on inadequate sensors. That was clearly demonstrated in one fatal Tesla crash that occurred in part because the car’s camera didn’t correctly identify an oncoming truck. To ensure smart vehicles have a reliable model of surrounding objects — particularly the ones the cars identify as “threats” — most rely on one or more lidars, or laser-based remote sensors.

Wireless power, the ability to deliver electricity to gadgets without plugging those gadgets into a cable, is a hotbed of innovation at the moment. The dominant standard, called “Qi,” is ever under attack from other efforts.

This week saw interesting developments from Energous (WATT), which aims to transfer power via radio frequency transceivers, with limited results so far, and some controversy about its business.

There are other contenders. On Wednesday in Las Vegas, during the Consumer Electronics Show, I met with Alex Lidow, who is founder of a privately held chip company EPC of El Segundo, California.

The year is 2022. You sit down at your office desk, back from Ikea with your new lamp. You take it out of the box, place it on the table, and it illuminates the workspace immediately. You then take your MacBook out of your backpack, place it to the right of the lamp, and it starts charging instantly. It sounds unreasonable to think that all this could become reality in just a few years. But behind closed doors, this technology already exists.

“A couple of months ago, we demonstrated an entire table top where everything on it was powered wirelessly,” Alex Lidow, CEO of EPC, tells Inverse. “A lamp, computer monitor, computer, cell phones being charged… all sorts of stuff.”

Since Nikola Tesla first experimented with wireless power during the early 1900s, there has been a quest to “cut the cord” – and go wireless. Today’s applications for wireless power undoubtedly extend far beyond Tesla’s wildest imagination, as we now have the ability to wirelessly charge cell phones, power tools, and even buses while at their scheduled stops, not to mention airborne drones while flying. However, despite strong consumer and business demand for wireless charging, power cords still reign. What explains the lag in our ability to power all of our electronic devices and appliances wirelessly?

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。
