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.

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.

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.

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.

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.

Light detection and ranging (lidar) is a versatile light-based remote sensing technology that recently has been the subject of great attention. It has shown up in a number of media venues and has even led to public debate about the engineering choices of a well-known electric car company, Tesla Motors. While this article is not going to enter the fray, it will provide some background on lidar and discuss its strong connection to power electronics technologies.

Lidar is a fantastic sensor for autonomous cars. Most companies developing self-driving vehicles seem to agree that the massive amount of long range, high accuracy data that you get from lidar is necessary, especially for complicated and variable urban environments. Really, the only reason why there's been so much focus on getting autonomy to work with just cameras and radar is that cameras and radar are cheap, and lidar is ridiculously expensive.

In this short video, EPC's Alex Lidow explains why GaN FETs can comprise circuits able to deliver Lidar resolutions down to a couple inches. Conventional silicon FETs performing the same tasks would be able to resolve images only down to a few feet. The secret is in the super-fast rise and fall times made possible by the GaN FETs.
