| 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. |
