Podcast: Moore's Law and GaN

Alex Lidow has deep roots in the electronics industry. His father and grandfather founded International Rectifier in 1947. Alex eventually ran the company himself for 12 years. He is currently the CEO of EPC, a company that manufactures gallium nitride-based power transistors and integrated circuits. These products are now found in lidar systems for autonomous vehicles, in 4G/LTE base stations, in DC-DC converters for servers and satellites, and in a wide variety of medical products.

EPC: Ahead of the Pack

EPC's chief executive, Alex Lidow, believes his GaN devices now beat silicon on performance and price, reports Rebecca Pool.

For EPC chief executive, Alex Lidow, this year's PCIM Europe 2019 has been all about applications. Presenting myriad enhanced-mode GaN FETs and ICs in end-products, the company is making a big play for 48 V DC-DC power conversion in advanced computing and automotives.

Powering graphics processors from a 48-V bus

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?

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?

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

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

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.
