Vicor Powers Unmanned Underwater Towed Vehicle

Vicor products’ rugged design takes them into many demanding applications, including marine environments. In one example, MegaPAC configurable power supplies are delivering the non-standard voltages essential for the successful operation of Triaxus, an innovative unmanned underwater towed vehicle used for oceanographic and environmental monitoring data collection, designed by underwater technology specialists the MacArtney Group. A complete Triaxus system comprises an on-ship industrial PC-based controller running a Windows software package, the towed vehicle and an armoured towing cable of up to 4000 m length. Within the cable, fibreoptic and copper cores carry data and power...

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

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...

Vicor V·I Chip™ modules improve ATE system design and save space

March 22, 2010
By

Vicor engineers recently helped an Automated Test Equipment (ATE) customer achieve an advanced distributed power supply architecture that delivers space savings, simplified mechanical design and several other benefits. The ATE has 13 DC outputs and draws 1.2 kW from a 110 – 220 Vac mains input. The ATE electronics had previously been powered from an externally mounted centralised architecture power supply. By exploiting the V·I Chip module family’s high power density, efficiency and flexibility, the power supply assembly has now been implemented on a single board that slots directly into the ATE chassis and...

Vicor Helps Power Solar Boat

Built in stainless steel, the stunning, 25-metre boat is manufactured by Kopf-Solarschiff for use as a sightseeing ferry with a capacity of up to 110 passengers and a range of up to 90 kilometres. A charge regulator, designed and manufactured by Uhlmann Solar with specialist support from Vicor is used to convert power from the solar panels into two batteries operating at different voltages: a 24 V battery is used to power the lighting and audio system, whilst a 300 V battery provides the drive power for the boat. Uhlmann Solar used four Vicor...

Vicor Modules Power On-Board Railway CCTV

Vicor VE-200 DC-DC converters are being used at the heart of the power block for a major new on-board CCTV system, installed by Portugal Rail, to increase passenger safety. The power modules are one of the most crucial components in the main ‘CCTV System for Transportation Systems and Passenger Transportation’ project. The design needed a nominal input of 72VDC, with outputs to 12VDC and 24VDC, both supplying 100W. Using the 12V VE-241-CW and 24V VE-243-CU DC-DC converters, and working with Vicor distributor Arrow Iberia, the design team followed Vicor guidelines to create an active...
