Digital Power System Management Eliminates blind Spot - issue 2/2011 May, 04 2011
Even though power management is critical to the reliable operation of modern electronic systems, voltage regulators are perhaps the last remaining 'blind spot' in today's systems, since they are without the means for directly configuring or monitoring key power system operating parameters....

Design of a High-Density Power Supply for FPGA's- issue 6/2010 September, 24 2010
Although the versatile and configurable nature of field programmable Gate Arrays (FPGAs) is attractive to system designers, the complex nature of design rules that govern the inner working of these devices and their outer interface protocols require extensive training, reference design evaluation, design simulation and verification....

Designing Multiple Load System Power Supplies issue 2/2010 April, 28 2010
Design tools have been developed over the past ten years to help power supply designers create single DC to DC power supplies. These tools feature parts selection, material cost calculation simulation and prototype procurement. This has simplified the design process and reduced time-to-market. But with design complexity increasing, the need for ten or more power supplies on a PC board has increased the challenge.

Monitoring Batteries improves UPS reliability - issue 1/2010 March, 25 2010
Systems from mobile telecommunications to data centres must operate with minimal downtime, making the reliability of the electrical mains supply a key concern. UPS's which provide back up power in the event of failure are therefore widely used to ensure critical electronic systems continue to function normally in the event that the mains power goes down...

Energy Efficiency Standards for Power Supplies September, 21 2009
A multitude of government energy efficiency standards and specifications have appeared over recent years that are driving the design of higher efficiency power converters. Efficiency requirements for External Power Supplies (EPSs) and other energy-using products (EuPs) from various agencies are discussed in this article, covering different power consumption modes. Resources are described that will help power design engineers understand efficiency requirements.

New Sensor Technology for Total Battery Management May, 21 2009
Whenever a battery is used as a critical source of energy such as with uninterruptible power supplies (UPS), electric vehicles (EV), hybrid electric vehicles (HEV) and mobile life support equipment, it is essential that the user has complete confidence in the battery’s ability to deliver its expected amount of energy.

Active ORing Solutions in Redundant Power System Architectures December, 02 2008
In its simplest form, an ORing device is a diode that protects the system against an input power source fault condition. A diode ORing device allows current to flow in one direction only, thus isolating the fault from the redundant bus, allowing the system to keep running off the remaining redundant power source(s).

Increased Development Efficiency through ECAD-MCAD Collaboration December, 02 2008
Collaboration between mechanical designers (using MCAD tools) and PCB designers (using ECAD tools) is becoming a priority for many product development teams. Allowing the PCB designer and mechanical designers to view layouts including thermal analysis, suggest and approve/reject changes, and view this information on their own tool is a large step forward in advancing this collaboration, with the ultimate goals being shorter design time with fewer re-spins.
