In the final installment of this series, how GaN has met the requirements to displace silicon is explored. As the adoption rate of GaN explodes, it is important to remember that, while GaN has made many advancements in just a few short years, it is still far from its theoretical performance limitations and thus there are profound improvements that can continue to be achieved. In time, the performance and cost advantages of GaN-on-silicon will result in a majority of applications currently using silicon-based devices converting to the smaller, faster, cheaper, and more reliable GaN technology.

In this conference GaN market and technology status will be addressed and its future evolution will be debated by mixing visions from designers, manufacturers, and end users.

EL SEGUNDO, Calif. — January 2019 — Efficient Power Conversion (EPC) is joining forces with Yole Développement (Yole) and SEMI to sponsor the first ever ‘GaN Con,’ an industry networking event covering the entire power GaN industry from manufacturers to end users. The theme of GaN Con is “Power GaN: From promises to possible market explosion” and is focused on the emerging GaN market and the state-of-the-art for its underlying technology.

氮化鎵元件對提升主流應用的效率的貢獻很大，例如在傳統矽基12 V - 1 V負載點 DC/DC轉換器。基於eGaN積體電路的12 V轉到1 V、12 A負載轉換器在5 MHz的頻率下，可以實現78%峰值效率及1000 W/in3 功率密度，而成本則低於每瓦0.2美元。

In the first article in this series, how gallium nitride (GaN)-on-silicon low voltage power devices have enabled many new applications, such as light detection and ranging (LiDAR), envelope tracking, and wireless power was discussed. In this article, more detail on one of these leading applications, LiDAR, will be explored. How GaN is being used to make LiDAR systems that see farther, with higher resolution, and at lower cost will be shown.

In recent years, GaN-based power conversion has increased in popularity due to the inherent benefits of eGaN FETs over conventional Si transistors. Migrating a converter design from Si to GaN offers many system-level improvements, which require consideration of all the components in that system. This trend has subsequently spurred a growth in the ecosystem of power electronics that support GaN-based designs.

Tuesday I was fortunate enough to have a meeting with Alex Lidow, founder of chip company EPC of El Segundo, California, and something of an luminary of the chip world. Lidow came up with the “power MOSFET,” a device that went on to be the basis of billions in semiconductor sales, in 1977.

His new company, whose initials stand for “Efficient Power Conversion,” proposes replacing silicon, the original basis of the MOSFET, and one of the most prevalent types of semiconductor around, with a different material, Gallium Nitride, commonly abbreviated as GaN — or “eGaN,” as Lidow calls the company’s new, improved form of GaN.

There have been several comparisons of eGaN FETs with silicon MOSFETs in a variety of applications, including hard-switched, soft-switched, and high-frequency power conversion. These studies have shown that eGaN FETs have large efficiency and power density advantages over silicon MOSFETs. Here we’ll focus on the use of eGaN FETs in synchronous rectifier (SR) applications and the importance of dead-time management. We show that eGaN FETs can dramatically reduce loss due to dead-time in synchronous rectifiers above and beyond the benefits of low RDS(on)and charge.

ANDOVER, Mass.—At the front door of Raytheon's Integrated Air Defense Center, there's a reminder of how big microwave electronics used to be—the original microwave oven. The now ever-present kitchen device was invented after a Raytheon engineer discovered his candy bar melted while he was standing near a magnetron used in a radar system the company was developing. Nearly the size of a refrigerator, the original microwave looks like it would cook a whole lot more than whatever was put within its metal grate, which was meant to contain the microwaves from its magnetron.
