Facts Say About An Account from a Scientist: he saved the world's 15% energy consumption prior. Now, he discovers silicon's replacement material

This scientist got his Ph.D 40 years ago who saved the world's 15% energy consumption at one time. He is continuing his journey of innovations now in discovering silicon's replacement material for humankind.

My father always taught me that the true worth of an individual is measured based on their contribution to society. As I entered graduate school in 1975 I knew my passion was in the field of semiconductors, and I felt my best contribution to society would come from finding a successor to silicon. I did my graduate work in Gallium Arsenide, but realized by the time I received my PhD in 1977 that Gallium Arsenide’s prospects were limited as a semiconductor due to the basic materials properties, I went to work applying everything I learned to making better devices in silicon.

GaN FETs Drive Fidelity and Efficiency in Class-D Audio Amplifiers

With the current maturity of Class-D audio amplifier architectures, amplifier fidelity and efficiency limitations are primarily at the device level. Silicon MOSFETs have been evolving for almost forty years, and their progress towards a perfect switch has slowed dramatically. There are some fundamental characteristics of MOSFETs that degrade sound quality and efficiency. In 2010, the enhancement mode Gallium nitride (GaN) power FET was introduced by Efficient Power Conversion (EPC), providing a large step towards the perfect switch.

GaN-on-Silicon Power Devices: How to Dislodge Silicon-Based Power MOSFETs

Gallium nitride (GaN) power transistors designed for efficient power conversion have been in production for seven years. New markets, such as light detection and ranging, envelope tracking, and wireless charging, have emerged due to the superior switching speed of GaN. These markets have enabled GaN products to achieve significant volumes, low production costs, and an enviable reliability reputation. All of this provides adequate incentive for the more conservative design engineers in applications such as dc–dc converters, ac–dc converters, and automotive to start their evaluation process. So what are the remaining barriers to the conversion of the US$12 billion silicon power metal–oxide–semiconductor field-effect transistor (MOSFET) market? In a word: confidence.

Power chips, but not as we know them

Max Smolaks welcomes gallium nitride, a new material which will replace silicon in the power chain

For the past 35 years, most power supplies have relied on power MOSFETs (metal oxide semiconductor field effect transistors) – voltage-controlled devices made of silicon that are used to switch and condition electricity.

Podcast: Cut the Cord! - How GaN Enables the Wireless Home

I was led to believe we were heading for a wireless world but a look behind my TV tells a very different story when I see all those wires everywhere. Not to mention the increasing number of BRIDGES for IoT devices. We were hoping to talk about the wireless powered home and how GaN (gallium nitride) is making that possible! When it comes to gallium nitride, there is only one man to speak with, and he's truly changing the world at EPC. He first appeared on EP180 talking about Why Gallium Nitride Is About To Disrupt Silicon then returned on 203 The LIDAR Technology Behind An X-Ray Pill. But he has returned to today to talk about how it can wireless charge anything, and it will blow your mind. Dr. Alex Lidow, is the CEO and co-founder of Efficient Power Conversion and he is going to talk about how tech will make power cords disappear and how EPC is leading the charge in the wireless space.

How GaN Power Transistors Drive High-Performance Lidar: Generating ultrafast pulsed power with GaN FETs

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.

Gallium Nitride maker EPC takes a big step forward in its quest to kill silicon chips

The $330 billion silicon chip industry is the foundation of everything electronic. But it’s slowing down as it reaches a new level of maturity that is prompting a bunch of mergers and acquisitions.

That’s why Alex Lidow, an industry pioneer and the chief proponent of an alternative material to silicon — gallium nitride (GaN) — feels like his time has come. His company, Efficient Power Conversion (EPC), is unveiling a new generation of eGaN chips that are half the size of previous chips and have significantly higher performance.

How we devised a wirelessly powered television set

Televisions can get their content wirelessly, but there is one set of wires they still need: those in their power cord. The consumer electronics industry has floated ideas for freeing TVs from their power cords, but this goal remains elusive. There are several reasons, such as the difficultly of meeting high-power requirements for large-screen TVs and the need for identifying an economical technology. Nevertheless, eGaN FETs could play a role in making TVs truly cordless devices.

GaN is Eyeing Silicon’s Data Center Lunch

As deep learning proliferates, the question of data center power density is once again on the rise, creating new business opportunities for specialized cloud services, hosted in facilities that can support north of 30 kW per rack, and companies in the power conversion space, who can tackle the density issue by making systems more energy efficient. Replacing silicon as the semiconductor material in power conversion chips with gallium nitrate, or GaN, leads to much smaller and more energy efficient devices that provide much faster switching.
