Solar Energy and the micro-inverters Product News 12/16/2009 1 comment New micro-inverter technology can pinpoint when a specific solar module is failing in an entire system so they can be identified and replaced on a regular service call.
Efficient power systems for portables Design How-To 12/16/2009 Post a comment The performance of power supplies for portable systems need to be improved on a constant basis. This how-to from Ittiam presents a generic power supply design for an embedded system and examines the function of each module in the design. It provides guidelines for selection of topologies and components, thermal and packaging aspects and even battery management.
Engineer tapped to head smart grid standards work News & Analysis 12/16/2009 Post a comment The U.S. government fueled significant work on smart electric grid this year, but the hard work of making the transition to a digital power network is just beginning, according to Steve Widergren, a principal engineer at Pacific Northwest National Laboratory recently named to head a broad new smart grid standards effort.
True power and current monitor offers power measurement accuracy benefits Product News 12/14/2009 Post a comment Linear Technology Corporation has introduced a power and current monitor for 4 V to 80 V systems that provides the necessary circuits to accurately measure, monitor and control power in situations where both the current and voltage may vary due to supply voltage uncertainty, component parametric changes, transient conditions or time-varying signals.
