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...

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...

Multiple Inputs Power Supply Architecture

Some electronic systems, such as field communication shelters or portable emergency equipment, must be able to operate from a variety of power sources, for example worldwide AC (85–264 Vrms), vehicle battery power, or portable generator sets, in both the 12 V or 24 V standards. In addition, these systems may also require backup power from auxiliary batteries in case the primary source is interrupted. An example of this power supply architecture is shown in the figure below (click for larger image). For AC line use, a front-end module accepts a universal AC input and...

Microlithography for the Semi-conductor Industry Using Laser Scanning

The PFC MegaPAC proves an ideal solution for a custom microlithographic processor. Depending on the semi-conductor manufacturers’ requirements, each system can be customised with a variety of output voltages, both positive and negative. The configurability of the product also means that lead times for this large piece of capital equipment can be reduced, improving the bottom line for the customer. Additionally, the modularity of the PFC MegaPAC enables fast system repair in the event of a supply rail failure. A similar microlithographic process is also used for making a display. In this processor, the photo...

Laser for 3D Glass Engraving

May 20, 2005
By

You may have already seen these nice little glass cubes with engraved 3-dimensional faces, animals, machines etc. They are manufactured by focusing a high power laser beam inside the glass. The energy of the laser beam causes micro explosions in the glass. The result is small white dots, and with hundreds of these dots a 3-dimensional picture appears inside the glass. Laser diodes are not only very expensive but also quite sensitive. Precise output regulation is necessary to control the current into the laser diodes. Vicor’s product was an ideal solution because of its...

PFC MicroS: Winning Combination of High Density, Low Profile

One customer uses two different PFC MicroS configurations in a semiconductor test system. The system is a very large climatic chamber that is configurable to allow the test of different semiconductor families. Dependent upon the type of DUT (device under test) the configuration of the power system is adapted to the task. The power system has three 3-phase 10KW main transformers that independently power the climatic chamber compressor, the control system and the test system. The test system uses 48 channels and each channel has its own dedicated test board that is capable of...
