EPC at APEC 2018 by EE Online

EPC CEO & Co-Founder, Alex Lidow gives Lee Teschler from EE World Online a tour of the EPC booth at APEC 2018 where EPC demonstrations included a high-power density 48 V – 12 V non-isolated converter capable of delivering over 700 W. In addition, a range of 3-D real-time LiDAR imaging sensors used in autonomous vehicles were displayed. Also, a single desktop implementing a high power resonant wireless charging solution capable of generating 300 W to wirelessly power a wide range of devices including cell phones, notebook computers, monitors, wireless speakers, smart watches, and table lamps.

Alex Lidow walks Alix Paultre through the EPC booth at APEC 2018

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".

Creating LIDAR apps with GaN speed, size, and power advantages

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.

Gaming laptops will have smaller power supplies with EPC’s gallium nitride chips

Gamers may not care about the finer points of gallium nitride (eGaN) chips as evangelized by power pioneer Alex Lidow, CEO of Efficient Power Conversion (EPC). But they will care that those chips will enable a new generation of gaming laptops with much smaller power supplies than in the past.

Will GaN and the Tesla SpaceX car survive space radiation? Yes and no.

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.

Best Practices for Integrating eGaN FETs

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.

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.

CES 2018 in Photos: What We Remember Most

LAS VEGAS — Once again the marathon that is CES is drawing to a close. Four days of trade show plus two days of media events. All sprawled across five miles of Las Vegas in some insane number of hotels and conference venues. As usual, I stuck it out so you don’t have to. Here are some of the images that struck me as interesting, weird, or just plain worth remembering:

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.

Why experts believe cheaper, better lidar is right around the corner

This article takes a deep dive into lidar technology. It explains how the technology works and the challenges technologists face as they try to build lidar sensors that meet the demanding requirements for commercial self-driving cars.

The bottom line is that while bringing lidar costs down will take a significant amount of difficult engineering work, there don't seem to be any fundamental barriers to bringing the cost of high-quality lidar down below $1,000—and eventually below $100. That means the technology—and ultimately, self-driving vehicles that depend on lidar—should be well within reach for ordinary consumers.

WIRELESS POWER GaN FETs Enable Large Area Wireless Power Transfer

To ensure widespread adoption, wireless power systems need to move beyond small charging pads and become active power sources over large surface areas. For magnetic resonant systems, this demands fundamental changes in coil technology, system architecture, and power amplifiers. Gallium nitride based amplifiers have proven capable of delivering 60 W with greater than 90 percent efficiency into the transmit coil over a wide load range.

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?
