Where GaN is Going in 2019…
Jan 07 2019

As the new year starts, it is worth spending a few minutes to review the successes of 2018 and look ahead to expectations for 2019. 

Over the past year, the applications taking advantage of GaN’s superior performance continued to expand and the knowledge base of GaN users continued to broaden.  The world has seen in operation the autonomous vehicles that GaN enables. Digital communications have been vastly improved with the use of GaN FETs and ICs in high speed, energy saving envelope tracking power supplies. The dream of a wireless world is coming closer to reality with the emergence of large surface area wireless power.

CES is the Global Stage for Innovation

CES is the Global Stage for Innovation
Dec 30 2018

World-changing innovations such as the first video cassette recorder (VCR) in 1970 to the world’s first laptop that can charge wirelessly have been announced at CES, the worlds gathering place for innovation.

World-changing innovations and Gallium Nitride (GaN), a critical building-block component behind many of today’s new and exciting consumer technology innovations such as self-driving cars, robots, drones, wireless power solutions, world-class audio and cutting-edge automotive solutions go hand in hand.

How to Get More Power Out of a High-Density eGaN®-Based Converter with a Heatsink

How to Get More Power Out of a High-Density eGaN®-Based Converter with a Heatsink
Dec 14 2018

eGaN FETs and ICs enable very high-density power converter design, owing to their compact size, ultra-fast switching, and low on-resistance. The limiting factor for output power in most high-density converters is junction temperature, which prompts the need for more effective thermal design. The chip-scale packaging of eGaN also offers six-sided cooling, with effective heat extraction from the bottom, top, and sides of the die. This application note presents a high-performance thermal solution to extend the output current capability of eGaN-based converters.

This post was originally published by Bill Kleyman on November 5, 2018 on the Data Center Frontier  web site. Learn more about eGaN technology and EPC GaN solutions for the Data Center.

The data center is an ever-changing entity and part of our technological landscape. But sometimes the biggest changes in the colocation industry happen at the core of what makes a data center tick, and may not be visible at first glance. In this instance, we’re talking about data center power, and the potential of creative solutions on the market, such as using Gallium nitride (GaN) in power conversion equipment.

eGaN® FETs and ICs Bring Precision Control to Surgical Robots

eGaN® FETs and ICs Bring Precision Control to Surgical Robots
Nov 14 2018

Minimal invasive surgery using surgical robots gives unprecedented control to surgeons looking to achieve the next level of precision, thereby reducing risk and trauma to the patient and speeding recovery. Many motors are required to control the various robotic appendages, such as arms, joints, and tool control, that give the surgical robot the required degrees of freedom (DOF) and dexterity to perform extremely delicate tasks. Weight and size of motor control circuitry are thus important factors in the design of such robots as they directly impact the size of the motor that manipulates the robot’s appendages during surgery.

The motor of choice for robotic surgery is the 3-phase brushless DC (BLDC) motor These motors are compact for their power rating, can be precisely controlled, offer high electro-mechanical efficiency, and can operate with minimal vibration when properly controlled. The choice of motor voltage lies in the range of 24 V to 48 V with balancing power conductor thickness and weight with insulation thickness and stiffness for optimum performance and dexterity being the determining factors.

Driving GaN Into The Fast Lane

Driving GaN Into The Fast Lane
Jun 12 2018

Ask EPC's chief executive, Alex Lidow, what the future holds for his GaN power device business, and automotive certification features prominently.

Recently delivering AEC Q101-qualified 80 V discrete transistors for LiDAR, 48V power distribution systems and other applications, the company's latest enhancement-mode FETs deliver higher switching frequencies and efficiencies than silicon MOSFETs, in a smaller footprint. And this is just the beginning.

"We have more transistors as well as integrated circuits designed for LiDAR [sensors] and are proceeding with automotive certification here," highlights Lidow. "LiDAR is under intense cost and performance pressure so integrating components and improving performance while lowering the cost is a big deal."

eGaN Technology is Coming to Cars

eGaN Technology is Coming to Cars
May 01 2018

Automotive technology has entered a renaissance with the emergence of autonomous cars and electric propulsion as the driving forces.  IHS Markit estimates that 12 million cars will be autonomous by 2035 and 32 million cars will have electric propulsion according to Bloomberg New Energy Finance, Marklines.  Both trends translate into a large growth in demand for power semiconductors.  This is also happening at a time when silicon is reaching its performance limits in the world of power conversion, thus opening a huge new market for power devices based on gallium nitride grown on a silicon substrate (GaN-on-Si). 

The Growing Ecosystem for GaN Power Conversion

The Growing Ecosystem for GaN Power Conversion
Mar 21 2018

There are many reasons to increase frequency of power conversion.  Fundamentally, these reasons boil down to size/weight reduction, and cost reduction.  There are several components in the design of a power system that must perform efficiently at the targeted increased switching frequencies.  These include power switches, power switch drivers, controllers, magnetics, and capacitors. Taken collectively, these components represent the high frequency power conversion ecosystem.  Without any of these elements, the benefits of increased frequency cannot be fully realized.

APEC 2018: GaN Revolution in the World of Power Electronics
Feb 28 2018

Come see the world’s smallest, most efficient, and lowest cost DC-DC converters!  eGaN technology makes this, and much more possible and will be on full display at this year’s American Power Engineering Conference, APEC, where power engineers from around the world gather to see and learn about the latest innovations and products available in the world of power electronics.

EPC GaN experts will be presenting a half-day educational seminar on the state of GaN technology and its application to leading-edge power electronics. In addition, EPC will deliver six technical sessions, as well as demonstrate eGaN applications in our booth and customer suite.
