Designers parallel their power supplies to increase system power output or to provide fault tolerance. In this column, Contributing Editor Tom Curatolo discusses various techniques for load sharing and the scalability of such architectures.
The footprint of a dc-dc converter is, to me, an interesting topic. There is a certain amount of history to it that’s kind of fascinating. Also, it really plays heavily into the decisions power designers make about what solution they’re going to use and w
Power supplies are often the last consideration in system design, which means custom work may be involved. This article explores the many ways in which power-supply vendors can work with design teams to satisfy system and cost requirements.
In my previous column (“Applications Drive Component Power Designs,” Sept. 11, 2008, p. 18, ED Online 19486), I contended that the application drives the selection of a specific power component—or it even forces the creation of a custom compon
Power designers often prefer particular power products or manufacturers. Some designers try to drive these preferences into every application. That’s not surprising. Such choices are usually based on successful relationships with specific manufacturers
Voltages are bussed around all the time, but the applications and voltage levels are many and diverse. One of the high-voltage apps du jour, for example, is the data center. Everybody knows about the phenomenal rise of the Internet over th
With each new generation of processor, the trend is toward lower voltages, higher currents, and faster dynamic loads. As a result, power-system designers are challenged to provide ever-faster transient response. They also have to do it usin
When I joined Vicor almost 20 years ago, the inventors of the brick told me that the planar surface of a base plate is optimal for removing or transferring heat and that potting provides an outstanding thermal interface around each component. When bri
