PFM™ Isolated AC-DC Converter with PFC

PFM™ Isolated AC-DC Converter with PFC

The new PFM™ VI Brick™ AC to DC converter is a flagship addition to Vicor’s power conversion range, which complements a growing array of VI BRICK and V.I Chip™ converter building blocks that provide unparalleled density, efficiency and connectivity from the wall plug to the point of load. With Adaptive Cell™ topology, the PFM™ delivers a low noise, power factor corrected 48 VDC 330 W output with consistent efficiency across the worldwide range of AC supply voltage levels – from Japan’s 85 V to the UK’s 240 V, and higher. The PFM VI Brick’s...

Power Supply Sequencing

Power Supply Sequencing

Voltage rails on electronics pcbs are proliferating as processors tend towards multi-voltage architectures and board designs incorporate multiple processors. Such proliferation brings complexity to the power switching task, because the supply rails must be powered up and down in the right sequence. Each processor’s voltage and timing requirements must be considered before adding to an overall scheme that meets the needs of all the onboard processors. Some processors use voltage – based sequencing (Turn on Rail 2 when Rail 1 reaches its set voltage) while others use time- based sequencing (Turn on Rail 1,...

Prestigious SPDEI Award Demonstrates French Distributors’ Recognition of Vicor’s Support

Prestigious SPDEI Award Demonstrates French Distributors’ Recognition of Vicor’s Support

Vicor has built its reputation over the years as a leading provider of power solutions through the quality and range of its products and of the support and commitment to its customers and distributors, internationally. This was independently recognised at the SPDEI Awards in Paris last November, where Vicor was named a Prize Winner in the Energy Category. Voted for by distributors, the awards recognise excellence across four criteria: distribution strategy; product innovation; technical and commercial support. SPDEI represents all major electronics distribution companies, and over 70% of the electronic component distributor sales force...

New Cool-ORing® Active ORing products provide fast fault current isolation for redundant 48 V and 12 V Applications

New Cool-ORing® Active ORing products provide fast fault current isolation for redundant 48 V and 12 V Applications

As today’s businesses depend increasingly on electronic data processing, continuous availability of their servers and communications equipment is critical. Accordingly, the power architecture used to support such loads typically comprises two or more redundant power sources driving a common redundant bus. In such designs, the loads must be isolated from possibly harmful reverse currents if either of the power sources suffers a short circuit failure. Diode ORing provides the simplest solution, but it has limitations. These are overcome by Picor’s Active ORing family, which now has two new members – the P12127 and the...

An accurately controlled, compact and cost reduced power source for OEM laser diode applications

An accurately controlled, compact and cost reduced power source for OEM laser diode applications

A Vicor customer based in Northern Italy designs, develops and manufactures diode based laser sources and systems for the industrial, medical and scientific markets. They can provide system, kit or component level solutions and develop products from initial concept through to full commercial production. Uses include laser markers for industrial and civil applications, and laser sources for health therapy. Laser diodes used in such applications require high current, accurately controlled electrical power. Delivering such current to the laser can be problematic, as typically the power source is at some distance from the diode. Passing...

New MIL-COTS VI Brick Filter adds MIL-STD transient and EMI compliance to power conversion design

New MIL-COTS VI Brick Filter adds MIL-STD transient and EMI compliance to power conversion design

Vicor’s new MIL-COTS VI Brick Filter provides a transient and EMI filtering DC front end to protect MIL-COTS power conversion systems, which complies with stringent military standards. It is available either as a stand-alone filter, or as an integrated Filter/PRM Regulator Module. Substantially smaller than competing products with similar power ratings, both versions of the MIL-COTS VI Brick Filter provide compliance with MIL-STD-1275A/B/D for transients, and MIL-STD-461E/F for EMI conducted emission and conducted susceptibility. The stand-alone Filter also complies with MIL-STD-704A/E/F for input transients, while the Filter/PRM Module complies with MIL-STD-704A-F. Both versions of...
