EPC: Ahead of the Pack

EPC: Ahead of the Pack

EPC's chief executive, Alex Lidow, believes his GaN devices now beat silicon on performance and price, reports Rebecca Pool.

For EPC chief executive, Alex Lidow, this year's PCIM Europe 2019 has been all about applications. Presenting myriad enhanced-mode GaN FETs and ICs in end-products, the company is making a big play for 48 V DC-DC power conversion in advanced computing and automotives.

Powering graphics processors from a 48-V bus

Powering graphics processors from a 48-V bus
New converter topologies and power transistors promise to reduce the size and boost the efficiency of supplies that will run next-generation Artificial Intelligence (AI) platforms. In all the topologies with 48 VIN, the highest efficiency comes with using GaN devices. This is due to their lower capacitance and smaller size. With recent pricing declines in GaN power transistors, the cost comparison with silicon-based converters now strongly favors GaN in all the leading-edge solutions.

Why go for GaN?

Why go for GaN?
GaN technology has matured to a point where it can challenge traditional silicon technology.  Gallium nitride(GaN)-on-silicon low voltage power devices have enabled many new applications since commercial availability began in 2010. New markets, such as light detection and ranging (LiDAR), envelope tracking, and wireless power, emerged due to the superior switching speed of GaN. These new applications have helped develop a strong supply chain, low production costs, and an enviable reliability record. All of this provides adequate incentive for the more conservative design ... Read more

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

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. ...

Lidar: A Gold Rush Is On to Help Your Car See Better

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.

EPC’s Wireless Power Fix: Get a Load of This Antenna

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 ... Read more

EPC is leading the world to a new age of wireless power

EPC is leading the world to a new age of wireless power

Nextbigfuture interviewed Alex Lidow, CEO of EPC. EPC is a leader in Gallium Nitride electronics and now is leading the charge to a new age of wireless power. In 5 to 10 years, we could begin to see entire houses or office buildings switching from costly wiring of buildings to a complete large area wireless solution.

The Race to Cut the Power Cord is Already Happening

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. ...

Why a world without power cords is now within reach

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 ... Read more

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

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 ... Read more
