When the issue invariably turns to the packaging of the power semiconductor – transistor, diode, or integrated circuit – the requests for improvement fall into six categories:

1. Can you make the package smaller?
2. Can you reduce the package inductance?
3. Can you make the product with lower conduction losses?
4. Can you make the package more thermally efficient?
5. Can you sell the product at a lower price?
6. Can you make the package more reliable?

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.

Last week, Anker debuted a tiny new power brick, crediting its small size with the component it uses instead of silicon: gallium nitride (GaN). It’s the latest example of the growing popularity of this transparent, glass-like material that could one day unseat silicon and cut energy use worldwide.

LIDAR is presently a subject of great interest, primarily due to its widespread adoption in autonomous navigation systems for vehicles, robots, drones, and other mobile machines. eGaN devices are one of the main factors in making affordable, high performance LIDAR possible in a small form factor thus further fueling the LIDAR revolution.

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.

In this video Alex Lidow, Founder and CEO of EPC, talks to Alix Paultre, Editor-in-Chief of Power Electronics News, about the various demonstrations of GaN-based solutions at the EPC booth at APEC 2018 in San Antonio, Texas. The high-frequency operation and other advanced performance advantages over Silicon enables GaN to empower applications from LIDAR to wireless power transmission. The booth exhibits include examples of these, from a real-time LIDAR demonstration to a running "wireless desk".

LIDAR is made up of a laser (or arrays) capable of transmitting pulsed light over the required range of interest, and a high-speed, low-noise receiver for reflected signal analysis. A portion of this light is reflected or scattered back to the receiver according to the reflectivity of the target.

Two space travel related stories hit my desktop this week; one that rapidly generated major international headlines and one that slid very quietly onto my email screen.

The headline-hitter was the successful launch of Elon Musk’s SpaceX rocket with its payload of a Tesla sports car, complete with a dummy driver at the wheel. The second was about Gallium Nitride technology that would be suitable for space applications.

SL70040SEH Low Side GaN FET Driver Powers ISL7002xSEH GaN FETs in Launch Vehicle and Satellite Power Supplies

TOKYO--(BUSINESS WIRE)--Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today announced the space industry’s first radiation-hardened, low side Gallium Nitride (GaN) field effect transistor (FET) driver and GaN FETs that enable primary and secondary DC/DC converter power supplies in launch vehicles and satellites, as well as downhole drilling and high reliability industrial applications. These devices power ferrite switch drivers, motor control driver circuits, heater control modules, embedded command modules, 100V and 28V power conditioning, and redundancy switching systems.

Best design practices utilize the advantages offered by eGaN FETs, including printed circuit board (PCB) layout and thermal management. As GaN transistor switching charges continue to decrease, system parasitics must also be reduced to achieve maximum switching speeds and minimize parasitic ringing typical of power converters.

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.
