Robert Gendron Explains Why 48 V is the New 12 V in this On-Demand Webinar

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. The smaller, lighter cabling is also cheaper, offers easier routing of power, and enables further energy savings, particularly in transportation applications where weight...

Whiteboard of the Week: Aircraft Cockpit Large Area Display (LAD)

An aircraft cockpit requires a complex power system: the large number of complex instruments require a variety of different power rails, whist space and weight must be minimized. The second Whiteboard Power Chain of the Week illustrates one solution developed by a Vicor applications engineer for one of our customers.
