36V Digital Potentiometers Support Wide Signal Swings and High Power-Supply Voltages
Microchip Technology Inc. announced two new volatile, SPI digital potentiometers (digipots)—the MCP41HV31 and MCP41HV51 (MCP41HVXX)—its first to operate at 10, 12, 18, 24 and particularly 36 Volts, for systems requiring wide signal swing or high power-supply voltages. Additionally, these digipots support both 7-bit and 8-bit resistor configurations, and a high terminal/wiper current, including the ability to sink/source up to 25 mA on all terminal pins for driving larger loads. These features, combined with an extended temperature range of -40C to +125C, make the MCP41HVXX well suited for a broad range of high-voltage and high-temperature applications, including those in the industrial, automotive and audio markets.

GridSTAR Net Zero Energy Demonstration Project underway at The Navy Yard
An extensive collaboration of researchers, manufacturers and economic development officials are embarking on a groundbreaking demonstration project for smart-grid, net zero energy buildings called the GridSTAR Center, a Smart Energy Campus initiative at The Navy Yard in Philadelphia. Spearheaded by Penn State University with support from the U.S. Department of Energy, Commonwealth of Pennsylvania and Philadelphia Industrial Development Corporation (PIDC), the GridSTAR Net Zero Energy Demonstration Structure is the first phase of the GridSTAR Center and will serve as a valuable hub for workforce training, building performance testing, energy management research and "smart" microgrid modernization deployments. Strategically located at The Navy Yard — which serves as a shining example of energy-related innovation and research — the structure is slated for completion this summer.

Maximising Synergies between Power Electronics and ICT for improving Energy Efficiency
Mike Hayes
Senior Program Manager, Tyndall National Institute
Around 40% of the world’s energy usage is in buildings and 50% is used in motors and drives. The power electronics “DNA footprint” is considerable in these domains. Savings of 10-30% are possible. A significant portion of these savings can be derived from embedding ICT into power electronics solutions.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
