Back to Basics: Why do we need active surge suppression?

Back to Basics: Why do we need active surge suppression?

It’s well understood that unexpected electrical disturbances can cause data loss or even permanent damage to any unprotected electronic equipment in their path. Active as well as passive suppression is essential to provide comprehensive protection from all such events. This post shows why this is so, and how active suppression works to fulfil its role. Electrical events threaten electronic equipment by placing excessive electrical energy onto its input power rails in the form of a transient, a surge, or possibly both. A transient is typified as a fast-rising voltage spike of high magnitude –...

Techniques to Deal with Beat Frequencies Caused by Paralleling DC-DC Converters

Power system designers are frequently required to develop solutions that provide more power than can be delivered by a single converter. Paralleling is a common technique, where the outputs of more than one converter are linked together to increase output current, and therefore output power. One problem with this approach is the generation of beat frequencies on the inputs of the converters.

See Vicor’s Presentation from INTELEC 2013

At INTELEC 2013, Vicor presented a paper that discusses the design of power adaptors that will step down a 400 V power rail to 48 V, discussing the efficiency, safety and power density as well as techniques to reduce any harmonics generated by the converters. If you weren’t able to attend INTELEC, you can catch up by viewing Power Adapter Design for 400 V DC Power Distribution in Electronic Systems below:   from View more of our presentations on SlideShare Related Information INTELEC 2013 – DC distribution: The way forward High-voltage DC distribution White Paper...

The Benefits of Designing Power Systems Using Power Components

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...
