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?

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.

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.
