L.A. Tech Execs Make 2016 Predictions

With the backdrop of slower global economic growth and expected higher interest rate in 2016, Alex Lidow, CEO of Efficient Power Conversion Corporation opines that companies looking for late-stage financing will see a greater emphasis on fundamentals such as revenue, margin and cash flow, and a lower emphasis on less-tangible metrics, such as the size of an audience without strong monetization.

The shrinking chip sector

With mega deals for mergers and acquisitions took place in the past year, would innovations be stalled? Alex Lidow, CEO of Efficient Power Conversion Corporation said if you look at semiconductor end sales in this century, we have only seen a 5% compounded annual growth rate. It’s clearly showing signs of an end market that is very large and very mature and in the same time, the cost for a new facility or new product has skyrocketed.

'Tis the season to be wasteful

In 2014, data centers in the United States consumed approximately 100 billion kilowatt hours (kWh) of energy. To add insult to injury, the power needed to support this rapidly growing demand comes from an electrical grid that is wildly inefficient and is based on infrastructure that was created, in large part, more than a century ago. Just how significant is this waste? It turns out that the power grid supplies 150W of power to meet the demands of a digital chip that may need only 100W. Moreover, the amount of wasted energy is even greater because every watt of power lost through power conversion is transferred into heat. And it is necessary to remove that heat from the server farm by expensive and energy-intensive air conditioning. It takes about 1W of air conditioning to remove 1W of power losses, effectively doubling the inefficiency of this power conversion process.

New materials have emerged that can convert electricity more efficiently and at a lower cost. By eliminating the inefficiencies in this final stage in the server farm power architecture we can realize a direct saving of 7 billion kWh per year. This is doubled when air conditioning energy costs are added, bringing the total to about 14 percent of the total energy consumed by servers in the US alone. The cost savings are also significant. At the average cost of $0.12 per kWh, that’s a savings of $1.7 billion annually, which does not include the additional savings in system cost resulting from fewer power converters and air conditioners.

How to get 500W in an eighth-brick converter with GaN, part 1

DC-DC “brick” converters are familiar to many engineers, and have wide usage in telecommunications, networking, data centers, and many other applications. This is due in large part to adoption of a common footprint defined by the Distributed-power Open Standards Alliance (DOSA) and generally accepted input/output voltage ranges. These converters provide isolation and voltage step-down, and have become increasingly sophisticated, with features that enable advanced system optimization and control.

Like Drug Companies, Big Chipmakers Are Planning To Spend On M&A Instead of R&D

“The semiconductor industry will become one where there are a lot of large corporations and smaller companies will, in effect, be outsourced R&D, much like the pharmaceutical sector,” says Alex Lidow, CEO of Efficient Power Conversion. He says in this scenario Qorvo Corporation and Intersil Corp. could become attractive targets.

Lidow, however, believes consolidation may bring a dark ages to innovation in the semiconductor industry.

Chip Makers Swept by Wave of Consolidation

Semiconductor firms have announced $100.6 billion in mergers and acquisitions this year. Chip makers have long used acquisitions to obtain new technology. But many recent deals resemble consolidation waves in older industries, motivated mainly by trimming costs in areas like manufacturing, sales and engineering.

Evolving eGaN FETs for power electronics

The combination of lower on-resistance, faster switching speeds, lower thermal impedance, and smaller physical size of eGaN FETs continues to raise the bar for power transistor performance. As GaN technology matures, not only does the performance of these transistors rapidly improve, but significant reductions in cost are also realized. Not only will GaN devices continue to enable new applications, they will replace silicon power transistors in cost-sensitive applications as well. As a matter of fact, the first signs of this happening are already here.

The Man on a Mission to Turn Silicon Valley into Gallium Valley

Alex Lidow, scion of an engineering dynasty, thinks the essential material at the heart of the tech industry needs to change. Lidow, 60, is currently head of a company called Efficient Power Conversion, and is one of the tech world’s loudest advocates for making transistors and semiconductors from gallium nitride. Silicon is traditionally used for the transistors and semiconductors on which the technology industry relies. This is an amazingly lucrative business: according to the Semiconductor Industry Association, which represents U.S.-based firms, the worldwide semiconductor industry was responsible for approximately $335.8 billion of sales last year alone.

Alex Lidow's Quest To Replace Silicon And Revolutionize Electronics

The company Alex founded in 2007, called Efficient Power Conversion, or EPC, is wholly dedicated to the task of putting GaN in the forefront for use in a variety of things. Wireless power transmission, Class D audio amplifiers, (using a small circuit board, this would produce less heat, and extend battery life on portable systems); and pulsed lasers, or LiDAR (Light Distancing and Ranging), designed to quickly create 3D images useful in mapping and meteorology.

Wireless Charging Metrics Debated

Wireless charging may have a standards battle to contend with, but there’s also a major a measurement problem. The quest for convenient living and energy conservation poses a ‘Ying/Yang’ dilemma living in the age of electronics. This is certainly the case with wireless power transfer technology. This rapidly emerging technology has the promise of “cutting the cord” and displacing the need for AC/DC wall adapters and perhaps eventually wall sockets. The question now is; will wireless power increase our carbon footprint by being less efficient than the traditional plug-in AC/DC wall adapters?” Are some wireless systems more efficient than others? These are two fundamental questions that need to be examined in an energy conscious world governed by energy efficient standards.
