Powering graphics processors from a 48-V bus

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 VIN, 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.

為什麼採用氮化鎵元件?

氮化鎵技術已經成熟至可以挑戰傳統的矽技術。從2010年起,商用的低壓矽基氮化鎵功率元件實現了很多全新應用。具備高速開關性能的氮化鎵元件也推動了全新市場的出現,例如雷射雷達、波峰追蹤及無線電源市場。這些全新應用有助供應鏈的開發、實現低製造成本及良好的元件可靠性記錄。這一切對於比較保守的DC/DC轉換器、AC/DC轉換器及車載應用的設計工程師來說,是很好的理據,是時候開始對氮化鎵元件進行評了。本文探討加快採納氮化鎵元件的各項因素。

基氮化鎵功率元件如何把矽基功率MOSFET逐出?

專為高效電源轉換而設的氮化鎵功率電晶體已經投產7年多了。全新的市場例如雷射雷達、波峰追蹤及無線電源,都成為氮化鎵的新興市場,因為氮化鎵具備超高速的的開關速度。這些市場使得氮化鎵產品得以量產、成本更低及具備優越的可靠性。這些優勢為比較保守的設計工程師提供更大的利好條件,因此,DC/DC轉換器工程師、AC/DC轉換器及車載應用工程師都開始對氮化鎵器件進行評估。要把120億美元的矽基MOSFET市場轉為氮化鎵市場,還有什麼壁壘呢?就是信心的問題。設計工程師、製造工程師、採購經理及管理層都必需對氮化鎵技術的優勢有足夠的信心、相信氮化鎵技術可以解決設計師對採用全新技術的風險的疑問。讓我們看看3個主要構成風險的因素:供應鏈、成本及產品的可靠性。

Lidar: A Gold Rush Is On to Help Your Car See Better

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.

EPC’s Wireless Power Fix: Get a Load of This Antenna

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 Race to Cut the Power Cord is Already Happening

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.”

Why a world without power cords is now within reach

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?

一位科學家的自述:曾為世界節省15%的電量,如今找到矽的替代物

這位在40年前成為博士的科學家曾為世界節省了15%電量,如今他正繼續自己的創新之旅,為人類找到了矽的全新替代材料。

我父親常常教導我:一個人的真正價值,是通過他對社會所作出的貢獻來衡量的。 1975年我進入研究生院學習,那時我的興趣在半導體領域,並且認為我對社會最大的貢獻,就是找到可以替代矽的半導體材料。我的研究生畢業課題從圍繞砷化鎵展開,但是直到在1977年獲得博士學位後,我才發現,作為一種半導體材料,砷化鎵受其基本材料特性所影響,它的應用前景非常有限,於是我轉而專注於研究如何製造出更好的矽基器件。
