TE Connectivity identified distinct industry demands and leveraged the company’s expertise and resources to form the TE Intelligent Buildings group. TE takes a holistic overview of any building environment and develops connectivity products that design engineers require to solve the electrical interconnection ch
The Energy Department's National Renewable Energy Laboratory (NREL) has published a report that aligns solar policy and market success with state demographics. By organizing the 48 contiguous states into four peer groups based on shared non-policy characteristics, the NREL research team was able to contextualize the
Kerite, a leading manufacturer of high quality insulated utility and industrial power cable, now offers a superior “wet design” for harsh utility operating conditions. This wet design is part of the standard Kerite utility cable construction. Utilities deal with flooded vaults, water soaked conduits and hi
Given the range of industrial applications is extremely diversified – from very small sensors powered by energy harvesting to mega processors used for process control and huge data computing capabilities required by some industrial equipment – the challenge for power designers remains the selection of
Delivering more than 200mA of output current can be a serious challenge for many high-voltage operational amplifiers. But for high voltage applications requiring as much as 1A of current, it is possible to meet this spec by pairing a current buffer with the op amp. What the current buffer brings to this arrangement is
The global market for power supplies crashed in 2012 as economic uncertainties led to low consumer demand and the postponement of large industrial projects. Whilst 2013 bought growth, it was limited to a few markets and the overall market grew by just 2.4%. However, the outlook for the global power supply market is
Advances in system level goals of the Smart Grid to better manage electrical loads during high demand time of use or during a shortage of available resources have created a need for efficient methods of connecting and disconnecting loads from the grid. Load management systems have been available in the commercial an
Software security in the grid is becoming increasingly important. There have been reports of appliances hacked to send SPAM, and The Wall Street Journal claims that the Smart Grid already has been penetrated and infected with potentially disruptive software programs. There are even fears that terrorists may pe
Designers of power control devices and those that combine control with power FET functionality are finding that FIB circuit edit techniques proven at older process nodes are delivering even greater benefits when used at advanced technology nodes. It is also expected that FIB circuit edit techniques wi
Intermediate bus voltages from 24V to 28V (nominal) are commonplace in industrial, aerospace and defense systems, where series-connected batteries may be a backup power source and 12V bus architectures tend to be impractical due to distribution losses. The widening voltage gap between the system bus and the po
Packaging for power electronics has evolved from simple metal bending to advanced materials and thermo-mechanical design, and from freestanding supply to integrated power management. System-size reductions made possible by higher switching frequencies and semiconductor miniaturization drove the early part of th
We here at Ridley Engineering recently conducted a survey with a group of almost 3,000 active power supply design engineers to discover the various reasons and circumstances they have encountered power supplies that failed. The experiences the engineers shared with us were very enlightening, and this article su
A joint exhibit called "EMC expert platform – smart grid and e-mobility“ the EMV show, held from 11 to 13 March 2014 in Duesseldorf, Germany, meets the requirements of the industry. Besides exhibits, visitors will find professional experts and discussions at the highest level. By impulse speeches the vi
Switching regulators are an excellent replacement for linear regulators in areas where low heat dissipation and high efficiency are valued. The switching regulator is typically the first active component on the input power bus line, and therefore has a significant impact on the EMI performance of the complete co
Governor Andrew M. Cuomo announced $30 million in funding available under the NY-Sun Competitive Photovoltaic (PV) Program to further stimulate large-scale solar and biogas projects in the Hudson Valley and New York City.
“Expanding the use of clean, renewable power in the Hudson Valley will help make New
The Power Sources Manufacturers Association (PSMA) Energy Efficiency Committee is sponsoring an Industry Session at APEC 2014. The session, “Energy Storage and the Power Converters that Control Energy Storage,” will explore various energy storage devices and applications, with an emphasis on the power electronics an
MISO’s newest region, South, joined the footprint on December 19, 2013. Three of the biggest drivers of price volatility in the region have been congestion on the ORCA 1 interface, Addis-Tiger congestion, and Grimes transformer congestion. Genscape has done a detailed examination of the drivers of this congestion an
Maxim Integrated has won a 2013 Elektra European Electronics Industry Award for Zeus, its highly integrated smart meter system-on-a-chip (SoC). Zeus combines accurate metrology, multiple layers of security and a wide range of communication functions on a single chip.
Zeus met the independent jury’s criteria
The rapid growth of distributed energy resources (DER) is raising concerns over the viability and necessity of new transmission lines. ICF International’s review and analysis of case studies concludes that targeted DER programs will reduce the need for transmission and distribution (T&D) investments in ce
