Thanks to their fast switching and reduced losses, SiC wide-bandgap devices help designers achieve efficient, integrated motor drives, enabling them to reduce size and get closer to the motor to lower costs and improve reliability.

by Ali Husain – April 20, 2021

The most important development in power electronics in recent years is the rise of so-called wide-bandgap (WBG) materials, namely silicon carbide (SiC) and gallium nitride (GaN). Read more

What’s the difference between power and energy density, and why is the former so vital to power-supply design?

To design robust power supplies, designers need to understand some basics and pitfalls.

Is power density the same as energy density?

Power density and energy density are quite different. Read more

Discrete GaN transistors, whether in die or packaged forms, offer high power density to boost pulsed signals in C-, L-, and S-band radars and communications applications.

The blame game is in full swing in the aftermath of Texas’ severe ice storm. Between February 14th and the 19th, Texas experienced record-setting low temperatures for a sustained period. It is estimated that over 3 million customers lost electricity, not just for hours, but for days. During the course of that week, many people also were without water. Read more

DEPARTMENT OF ENERGY – JANUARY 15, 2021

WASHINGTON, D.C. – Today, the U.S. Department of Energy’s (DOE) Office of Fossil Energy (FE) announced plans to make $160 million in federal funding available to help recalibrate the Nation’s vast fossil-fuel and power infrastructure for decarbonized energy and commodity production. The funding, for cost-shared cooperative agreements, is aimed to develop technologies for the production, transport, storage, and utilization of fossil-based hydrogen, with progress towards net-zero carbon emissions.

First Report Outlines Four Phases of Utility-Scale Energy Storage Deployment, Providing a Potential Roadmap to 100+ Gigawatts of Installed Capacity in the United States
Jan. 26, 2021

With declining costs, improved technologies, and increasing deployment, energy storage is poised to become a growing part of the evolving U.S. power system. But measuring the value of energy storage is inherently complex—and future systems will likely include multiple storage technologies, adding new complexity. Read more

Soon, your home may be able to generate solar power from places other than your roof. As the solar market evolves and expands, companies are looking into new solar technologies aimed at spreading solar energy generation beyond traditional rooftop and ground-mount solar panels. One such idea, solar panel windows, has gained momentum recently, and could represent part of the solar market’s future. Read more

“This year will likely be remembered as a period of technology consolidation rather than breakthrough innovation in the energy industry. Emerging industries such as offshore wind and lithium-ion battery storage have gone from strength to strength. 

Meanwhile, more novel technologies such as energy blockchains and flow batteries have been relatively quiet this year. Read more

A possible breakout moment for emerging technologies like storage and hydrogen

Both energy storage and hydrogen – critical emerging technologies for unlocking emissions reductions across energy systems – could become key beneficiaries of stimulus plans, much as solar PV and wind benefitted from boosts during recovery packages after the 2008 financial crisis. Read more
