Why Choose Active ORing Instead of a Traditional Diode?

An interview with Chester Firek, Senior Product Marketing Manager for the Vicor Cool-ORing family of Active ORing  power management solutions. The discussion covers the advantages and challenges of Active ORing over traditional diode solutions. There’s also a white paper and Cool-ORing family product matrix at the end of the post.

Background to Factorized Power Architecture

Supplying power to early electronics systems was relatively straightforward and could typically be accomplished with a single silver box AC-DC supply. However as system performance, power density and load voltage proliferation steadily increased, more sophisticated power systems architectures became necessary. This article looks at this evolution and introduces Factorized Power Architecture, which allows designers to meet the challenges of today’s high-performance electronics. Some History and Some Problems In the beginning, there was 5 V, and it was good. In the mid Eighties you could build a 19” VMEbus system with several MC68000 processor boards,...

Addressing the New Challenges in Power Distribution

Power supplies have traditionally been designed as “silver boxes” or “bricks”: a self-contained, autonomous voltage-in, voltage-out device, with minimal-impact mechanical and electrical integration with the host system. However, evolution of system requirements – higher power, higher density, higher input voltages, higher load currents and last but not least, higher efficiency –  clearly requires alternative, integrated approaches. With each generation of processor, memory, DSP and ASIC chip, lower voltages at higher currents challenge the infrastructure to supply contemporary “loads” with the requisite electrons.  Electricity from an AC outlet, or a wall plug, typically goes through...

How to Meet European Standards for Rail Applications

September 4, 2011
By

In this video, Marco Panizza, Vicor’s European Applications Manager shows how Vicor’s modular DC-DC converters can meet or exceed European railway standards IEC571/EN51055 and RIA12 if design guidelines are carefully followed. These standards address the harsh environment issues that characterise rail applications, including shock, vibration, extreme temperatures, restricted space, varying voltages, EMC and reliability.

The drive to create metadata processing server systems plus the parallel push for increased port density and triple-play (voice/video/internet) traffic handling in telecommunication systems places greater demands on power management architectures. The problem: inefficient power architectures Traditional designs using AC to 12 Vdc Silver Box followed by 12 V to 1.x Vsynch buck have run aground in terms of system power density and efficiency due to a combination of distribution bus losses and fundamental restrictions in topology performance as processor voltages reach sub-volt levels. Higher voltage (48 V or 350/380 V) bus voltages reduce...
