Whiteboard: A New Way to Simplify Power Chain Analysis Aired November 2014
48 V is the New 12 V: Increase System Density and Efficiency Using 48 V Direct to the Load
Presenter: Robert Gendron, Vice President, Picor Semiconductor Power Solutions
001x001px_alpha.png 001x001px_alpha.png
English   Description
Power system designers in a variety of applications, including telecoms, data centers, automotive, industrial, lighting and aerospace, have long relied on a 12 V intermediate (or hub) bus to distribute electrical power. With increasing demands for higher output powers in smaller spaces, and the need to improve efficiency, 12 V is rapidly being replaced with 48 V. By moving to a higher voltage, engineers reduce the I2R loss in cabling, improving power efficiency. This webinar walks through the benefits of 48 V power distribution in a typical data center application. Robert explains the benefits of the higher voltage and shows new components that will convert directly from 48 V to low (even sub-1 V) voltages for the load in a single conversion stage.

Whiteboard: A New Way to Simplify Power Chain Analysis Aired April 2014
Whiteboard: A New Way to Simplify Power Chain Analysis
Presenter: Sean Crilly, Vice President, VI Chip Design Engineering
001x001px_alpha.png 001x001px_alpha.png
English   Description
Designing power chains is often an iterative process, with engineering sketching ideas on a whiteboard, estimating performance and then repeating the process for alternative approaches. This webinar demonstrates how online tools dramatically speed up the process. During the webinar, Sean will walk through the design of a number of power systems, explaining how tools can be used to identify architectures and components to create a power chain that meets requirements. He will then demonstrate how to analyze the electrical and thermal performance of each design, accurately calculating overall system efficiency. This allows engineers to quickly identify the most appropriate system for the application.

Topics covered include: using the Solution Selector to build topologies to meet your requirements; selection of optimum topologies, based on figures of merit; transferring your design to the Whiteboard; modifying the design and simulating distribution resistance; analyzing the power chain performance and thermal characteristics; and using application-specific reference designs

Next Generation Combat Vehicle HVDC Electrical Power Architecture Development
001x001px_alpha.png
Presenter: George Hamilton, Deputy Associate Director, US Army RDECOM-TARDEC001x001px_alpha.png
Moderator: Stephen Oliver, VP VI Chip Product Line
001x001px_alpha.png
English   Description
The TARDEC architecture uses HVDC power distribution, which offers many advantages: it can be used to recover inertial energy, allow designers to switch from hydraulics to electric motors and drive auxiliary functions (e.g. air-con) from more efficient electrical power, rather than an inefficient idling diesel engine. One challenge, however, is the need to offer bidirectional power transmission to allow charge of the battery, and deliver this energy when the combustion engine is not running. George will explain why relying on diesel engines is inefficient; example HVDC schematics for military land vehicles; how to create a bidirectional HVDC system to enable battery charging; and the standards that need to be considered.

English   Description
For hybrid automotive, earth-moving equipment and transportation applications HVDC power distribution can signficiantly improve efficiency, whilst reducing size and weight, enabling extended range, higher performance and lower cost. Driving auxiliary functions from more efficient electrical power and switching from hydraulics to electric motors can enable further savings, particularly in earth-moving equipment. This webinar describes these trends, and explains how modern power components simplify the development of HVDC systems for transportation applications.

Topics covered include causes of energy wastage in large diesel vehicles; the benefits of HVDC in transportation applications; example HVDC schematics for commercial and industrial land vehicles; how to use bi-directional converters to enable charging and regenerative braking vehicles; and how new power components simplify HVDC design in transportation applications

380V HVDC in Commercial Buildings and Offices
001x001px_alpha.png
Presenter: Dipl.-Ing. Bernd Wunder, Project leader LV-DC Grids, Fraunhofer IISB (DCC+G)
Moderator: Stephen Oliver, VP VI Chip Product Line
001x001px_alpha.png
English   Description
Reduction in energy consumption by buildings has become a key focus for the EU. A Zero Energy Directive will require that all current public buildings consume nearly zero-energy by 2018; and from 2020 any new buildings be constructed to consume nearly zero-energy, requiring a move to integrated renewable energy sources. Using real-life examples, Bernd Wunder discusses how the use of DC grids in buildings can increase the efficiency of electrical distribution by up to 5% and boost solar power system efficiency by 7%. With buildings consuming 40% of Europe’s energy, Bernd will show how this technology is an essential component of strategies to achieve governmental targets.

Topics covered include: benefits of HVDC and design approaches in commercial buildings; how HVDC can achieve energy savings in commercial buildings and offices; and examples of HVDC equipment that is enabling the transition.
