White Paper Describes How Eliminating Isolation Improves Performance of 48 V Power Systems

The telecommunications industry has traditionally used positive-referenced DC power distribution to reduce the chance of copper wiring corroding. Modern systems, however, often use active cathodic protection, eliminating the need for a positive-referenced power system.

Vicor Provides Digi-Key with Another Geek Moment

April 8, 2014
By

The Digi-Key Another Geek Moment video series is a favourite for engineers, providing interesting and unusual demonstrations of the capabilities of different manufacturers’ products. In a recent video, a Vicor AC-DC supply is coupled with one of our IBCs, which steps down 48 V to 12 V, to start an all-terrain vehicle (ATV or quad bike). The demonstration illustrates an important point: some applications require very high peak currents, which many power supplies struggle to deliver.

Fast, Online Simulations Shape Advanced Power Supply Architectures

The task of the power system engineer grows steadily more complex. At the level of individual PCBs, semiconductor devices – microprocessors, FPGAs and the like – demand a range of discrete voltage levels, frequently at around 1 V and at currents of tens of Amps. The physics of distributing power at these levels mandates regulation as close to the point-of-load as possible: I2R losses and minute but inescapable inductances are always poised to degrade the performance of low-voltage, high-current paths that see rapid step-changes in power demand. At the other end of the power-conversion...
