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...

Vicor 48 V Direct to Processor Conversion

New solution eliminates need for intermediate 12 V stage The computing load now presented to data centers has become so intense that it has meant that the power schemes, architectures and component parts have been required to undergo a tremendous change. I recently interviewed Robert Gendron, Vice President of Vicor’s Picor division, about the company’s recent innovations that eliminate the need for intermediate voltage stages when converting from 48 V to the voltages required for modern processors. Space availability on the processor board, together with the urgent need to contain heat losses and spiraling...

White Paper Explains How ZVS Technology Enables Higher Power Throughput in Buck Regulators

January 28, 2014

The efficiency of conventional hard-switched niPOL regulators drops as the step-down ratio increases, and falls dramatically when required to accept a wide input range with step down ratios approaching 36:1. This means that designers have been forced to incorporate multiple converter stages, limiting the step-down ratio of each stage to maintain efficiency at acceptable levels.

The Benefits of Designing Power Systems Using Power Components

One of our most popular webinars to date shows how to design complex power systems using power components and a simple three-step process. In his presentation, Paul Yeaman, Director, Applications Engineering at Vicor, walks through the three stages of a process that simplifies power system design: identifying, architecting and implementing.  An approach that has helped many engineers to develop power architectures quickly and efficiently. The presentation isn’t just about this new design approach; Paul also had some very interesting things to say about the benefits of using power components. Paul states that the three...
