Electric Vehicle

Electric Vehicle

In a recent application, the customer used two DC-DC converter modules, in parallel with current sharing and battery charging circuitry to provide power from a high voltage battery to the Smart Car’s standard 12 V electric system. The 316 Vdc battery is fitted in an insulated container under the car’s floor to provide traction via compact electric motors, instead of the normal petrol engine. In short, Vicor modules are being used as a solid-state alternator. Although the car has a small 12 V battery, to supply peak power and emergency back up, the two modules...

Display In-Flight Simulator for Helicopter

Display In-Flight Simulator for Helicopter

Pilots around the world regard flight simulation as the closest thing to the true experience of flight. One Vicor customer specialises in the design, manufacture and integration of high-resolution display systems. Applications include simulation, command and control, and virtual reality. The basic characteristics of the display – resolution, field-of-view, brightness and contrast – are optimized to meet the most rigorous training scenarios, like landing and takeoff for pilot training, complex combat scenarios, air-to-air, air-to-ground.   Vicor has various applications in this market, using our easily configurable power supply products, PFC MegaPACS. The truly user configurablity of...

Speedometer for Buses and Subway

Speedometer for Buses and Subway

Vicor modules (VI-J00 products) are used to redesign speedometers for urban transport such as buses and subway trains. Using the ‘T’ input voltage range, Vicor modules are very well suited to the transportation field. ‘T’ input voltages range from 66 to 160 Vdc and fit with 72 Vdc; 96 Vdc, and 110 Vdc, with the same part numbers. Vicor modules were suitable for this project because of the wide input voltage range: 66-160 Vdc. The low storage and operating temperatures were also of benefit to the client; the baseplate can be put onto a...

High-boost Harmonic Attenuator Module

  Vicor’s high-boost VI-HAM is a universal AC input, PFC front-end module that has been optimised for use with Vicor’s V375 series of DC-DC converters. A single high-boost VI-HAM may be used with any combination of V375 series DC-DC converters up to 600 Watts, resulting in a power conversion system with high power density, few components, and low cost Parallelable versions of the VI-HAM are available for applications requiring over 600 Watts of output power. In addition, the high-boost VI-HAM is fully compatible with Vicor’s VI-26x and VI-J6x series DC-DC converters, giving designers the...

Output Voltage Trimming

The nominal output voltage of Vicor’s DC-DC converter can be trimmed up or down within a specified range. Most of our 1st Gen converters can be adjusted between -50% and +10% (except outputs between 10V and 15V, which are limited to a range of +/- 10%). All our 2nd Gen converters can be trimmed down to 10% or up to 110% of nominal output voltage. Fixed set output trimming can be achieved using a single resistor or by using a potentiometer when variable outputs are required. The use of an OpAmp or DAC gives...

MRI Scanning System

The system is designed specifically for in-office musculoskeletal imaging, bringing MRI to the patient, and thus reducing the need for hospital visits. The compact, modular design requires as little as 8.4m2 and the low field MRI magnet is optimized for orthopedic use and imaging of extremities. Patients remain outside the magnet at all times during the examinations, enabling constant patient-technologist contact. This MRI system uses Vicor’s Junior modules in the temperature control system, where it is vitally important to keep the MRI magnets at a constant temperature.

Vicor’s Flexible Route to RoHS Compliance

For many manufacturers product compliance to the European environmental RoHS hazardous material standard will be compulsory by 1 July 2006. To help ease our customers’ transition to RoHS compliance, Vicor will be offering our standard Brick products in both RoHS compliant and non-RoHS compliant options. Customers who manufacture using lead/tin solder processes can continue to use our existing non-RoHS compliant products which incorporate lead/tin connector pins. Customers transitioning to RoHS can now select RoHS-compatible pin styles. Evaluation samples of most RoHS compliant products can be ordered now and volume production will follow shortly. Most...
