Vicor Power Techtorials Series provides expert advice on the most-asked-about power system design topics. These topics are collections and distillations of points from Vicor applications engineers addressing real-world questions posed by power designers worldwide. We offer them in form of videos (available also on CDs), webcasts and more. The interactive techtorials also contain links to the Internet for access to product data sheets, related articles and application notes.

Vicor DC-DC Converter Theory »
Presented by Marco Panizza, Manager, European Applications Engineering. Includes descriptions of the DC-DC converter power train, Maxi, Mini, Micro block diagrams, and ZCS power transfer topology.
Peter Huber, Senior Field Applications Engineer, Germany provides both the theory and a step-by-step bench demonstration here he measures output ripple. He also shows a range of methods for reducing output ripple while stressing the importance of good technique.
Input Overvoltage Protection »
Input Overvoltage Protection, presented by Marco Panizza, Vicor's European Applications Manager, defines the types of transient overvoltage and discusses methods to generate and measure them.
EMI Filtering - How to get the lowest noise »
Peter Huber, Senior Field Applications Engineer, describes the sources of current mode and differential noise. He demonstrates the effect of various filters and combinations on noise spectra, shown in the context of EN55022, Class B limits.
Thermal & Mechanical Considerations »
Macro Panizza, Manager, Applications Engineering, defines the terms and relationships among efficiency, heat, cooling by conduction, convention and radiation. Using these relationships, he performs the calculations to determine efficiency and thermal impedance, leading to choose a proper heat sink.
David Berry, Field Applications Engineer, delineates the primary reasons for paralleling DC-DC converters: to increase power or provide fault tolerance. In that context, the value of current sharing and methods of achieving it are described. Lab demonstrations are used to visually reinforce the major points.
