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...

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...

380 Vdc to 48 Vdc High-Efficiency Powertrain Conversion

Complete power-train conversion, from 380 Vdc to a standard 48 Vdc rail, can be achieved with a new Bus Conversion Module (BCM™) from V•I Chip Corporation, The VIB0002TFJ features a MHz-switching zero-voltage switching (ZVS™), zero-current switching (ZCS™), sine amplitude converter (SAC™) to achieve a high power density of 1,150 W/in3 and over 95% efficiency. In eco-array configurations, efficiency is over 90% from a 10% light-load, to full-load at multi-kW power levels. Established factorised power architecture components supply an easy and efficient step from the 48 Vdc rail to high-current, sub-1 V loads. The exceptional...
