PSD Podcast Focuses on Component Power Design Methodology

In the latest Power Systems Design podcast, Paultre on Power, editorial director Alix Paultre interviews Christoph Wieser about component power design methodology. In the interview, Christoph explains how this approach allows engineers to design power systems quickly and easily, reducing the time required to architect power chains. He also describes how improvements in functionality, power density, thermal design and other factors have allowed the creation of components that enable the methodology. Paultre on Power is a multi-lingual podcast, and this interview was conducted in both German and English. Click below to listen to the...

Vicor Hosts Power Design Seminars in Three Indian Cities

September 9, 2014
By

Vicor will run three half-day seminars in India that will help engineers design and optimize power systems from source to point of load.  These events will be held in Bangalore, Hyderabad and Pune. The seminars will cover a range of topics relevant to designers developing systems for a wide variety of applications. Attendees will learn about the latest DC-DC and AC-DC power components; online tools that can simulate and analyze power chain designs; and techniques to manage isolated and non-isolated loads. The seminars will also describe how using components based on the ChiP platform...

White Paper: A Novel Approach to Industrial Rectifier Systems

AC-DC converters for industrial applications have been relying on double-stage architecture for quite a long time. A non-isolated, single- or three-phase, single- or multi-level stage typically feeds an isolated DC-DC stage, with capacitors between the two stages providing the necessary energy storage. The need for high efficiency and high density has determined the evolution of distributed power systems toward architectures that employ optimized power components. Among those power components, fixed-ratio bus converters have been developed to provide state-of-the-art performance, including components capable of 300-400V DC input that provide isolated, Safety-Extra-Low-Voltage (SELV) output. This paper,...

EDN Highlights the “Power Players” in the New War of Currents

Steve Taranovich, editor at EDN, has just written a fascinating article that discusses the new “War of Currents”. The emergence of HVDC power distribution has reopened the AC-DC debate, but Steve doesn’t see this as a winner-takes-all competition, rather he believes that both approaches will be used in a hybrid approach. As he says, maybe this means, “Tesla and Edison may now rest in peace”. This article is a great companion to Stephen Oliver’s recent HVDC webinar series, where he was one of the first to suggest the concept of a new war of...

Vicor PowerBench Tools: The Filter Design Tool

Input filters are a critical element of power systems, particularly when demanding EMI requirements must be met. But input filter design can be a complex and time consuming process. If you are responsible for input filter development, try the Vicor PowerBench® Filter Design Tool, a free online calculator that will help you develop a filter that meets your system’s requirements. The Vicor Filter Design Tool offers a wide range of options. You set the attenuation and frequency at which the attenuation is achieved, and then simply select the filter topology to be used from:...
