Environmental Requirements for COTS Power Supplies

This post, the third in the series about requirements for COTS power supplies, describes tests that ensure that the equipment is properly designed to meet the environmental conditions that it may face during its service. Many of these tests are very stringent: if these demanding requirements must be met, then often a custom solution is likely to be required.

White Paper: Leveraging Bus Converters in Regulated DC-DC Applications

White Paper: Leveraging Bus Converters in Regulated DC-DC Applications

This paper, presented at PCIM 2014 by David Bourner, one of our applications engineers, provides a comparison between Factorized Power Architecture (FPA) and the Yeaman Topology in a regulated, high density DC-DC application. It describes a variant on FPA that utilizes a Power Component Methodology, and compares FPA solutions against the Yeaman Topology. A description of the investigation methods used and outcomes of various tests to establish performance metrics follow. Practical aspects of applying power components to both FP and YT architectures are followed by a summary of salient attributes for each system. The Yeaman...

Back to Basics: Using Hot Swap to Minimize Downtime

Back to Basics: Using Hot Swap to Minimize Downtime

Given the critical role of modern telecommunications and data communications equipment, maximizing its online availability must always be the first priority. Clearly, any equipment’s availability depends critically on that of its power supply. Fortunately, close to zero power system downtime can be effectively achieved by combining two techniques – redundancy and hot-swapping. In this back-to-basics post we will see how these work together, and how systems can be designed for hot swapping. Consider for example a rack-mounted telecommunications system comprising modules plugged into the rack’s backplane, with a total power requirement of 120 W...
