Regulators reduced net metering incentives for both existing and future solar customers
Krysti Shallenberger & Gavin Bade for UtilityDive
The Nevada PUC’s decision to reduce net metering rates at the end of last year set off months of regulatory and legal challenges.
In their decision, regulators reduced net metering incentives for both existing and future solar customers — and made the unprecedented decision not to “grandfather”

National Offshore Wind Strategy Plan
U.S. Secretary of Energy Ernest Moniz and U.S. Secretary of the Interior Sally Jewell announced the publication of a collaborative strategic plan to continue accelerating the development of offshore wind energy in the United States, the National Offshore Wind Strategy: Facilitating the Development of the Offshore
The capacity of lithium-ion batteries might be increased by six times by using anodes made of silicon instead of graphite. A team from the Helmholtz-Zentrum Berlin (HZB) Institute of Soft Matter and Functional Materials has observed for the first time in detail how lithium ions migrate into thin films of silicon.
Wildcat Discovery Technologies, a technology company using high throughput methods to develop improved battery materials, is pleased to announce that it has been granted three patents from the United States Patent and Trademark Office for its groundbreaking copper fluoride cathode Wildcat calls "CM4".
µModule® Regulator with Precision DC & Transient Voltage Accuracy for Advanced Digital Devices

Banks and nations are starting to move from financing high-carbon to investing in low-carbon fuel sources. For example, the World Bank, the second largest multilateral finance institution, says it no longer invests in most coal projects, including new power plants. A select number of governments have also indicated

IBC SOLAR, a leader in photovoltaic (PV) systems and energy storage, is cooperating with the Swiss energy provider EKZ. The focus lies on the distribution of IBC SOLAR’s quality PV components for private customers.
This cooperation with one of the largest Swiss energy suppliers is already
Renewable electricity documented with Guarantees of Origin
The demand for renewable electricity in Europe, documented with Guarantees of Origin (GOs), grew briskly in 2015 – up more than 9% from 2014 and surpassing 343 TWh. “Behind this growth are thousands of businesses and millions of households in numerous European countries – voluntarily purchasing renewable

Smaller, smarter, and more powerful are market trends for low-power switched-mode power supply (SMPS) applications. Smaller requires the SMPS to have a more compact form factor – and, thus higher power density. Smarter requires intelligent system-to-system/system-to-human communication to ensure the systems

Industrial automation systems are undergoing a revolution to reduce latency and down time. This directly translates to increased profits for factory operators and machine builders. Dubbed Industry 4.0, this effort will add more intelligence across the factory floor from HMI panels and controllers to communication

In response to Google’s Little Box Challenge (LBC), our Virginia Tech team, the Future Energy Electronics Center (FEEC), decided to design a power inverter. As shown below, our design significantly surpassed the LBC specifications.
Our final design exhibited a power density of 61.2 W/in3,

It should come as no surprise to anyone that a the continuing adoption of Digital Power System Management (DPSM) within the communications and computer industries continues to be driven, in large part, to the high current levels demanded by the sub-20nm ASICs and/or FPGAs that are at the core of their

Here we’ll show how Spice can be used to provide proximity loss results for magnetics windings. Proximity loss equations are solved for a set of frequencies, and a simulation circuit is generated which predicts the proper AC losses regardless of the current waveform.
Inductor winding AC

In the last part of this series, we saw that only one of the modulator gains found in the literature can be confirmed with measurements. Furthermore, it is shown that the discrepancies in all the models are easily resolved by proper sampling of the system.

The implementation of the “Smart Grid” is accelerating rapidly. Once just a vision in eyes of power engineers and utilities, the Smart Grid is swiftly taking shape. A major driver in realizing a truly smart electrical grid is the adoption of distributed energy resources (DERs). Grid-connected

In the last few years GaN based devices, both discrete FET’s and MMIC’s, have been released and widely used in high power microwave amplifier systems. These devices, available from several foundry sources, are typically fabricated on 100mm SiC wafers. GaN on Si processes are also under consideration,

Thermal behavior is important to determining the lifetime performance of electronic system design and the power supply is a critical element in determining that behavior. Heat has a number of effects on a system. The most problematic at a system level is one of long-term reliability. High operating temperatures
Phil Ebbert, Riedon
Measuring the resistance of something is a great deal more complicated if that resistance is very small. With bigger resistances, measurements can be as simple as connecting two leads between a digital multi-meter (DMM) and the device under test (DUT) and reading the number. With small resistances, the multitude
