New Tram-Trains Using Tyres

New Tram-Trains Using Tyres

This new rubber-tyred vehicle system takes bus and tramway and combines the advantages of the two systems: better stability, a smoother ride for travellers, only one central rail, more flexibility and, with a diesel engine, it can be used on every road. Vicor modules (VI-J00 products) are used in this modern system of transportation. With a wide input voltage range of 18 – 36 Vdc, a high reliability (MTBF), low size and weight, and ease of use, the Vicor modules provided the ideal solution.

Improving Output Ripple

Improving Output Ripple

Vicor’s DC-DC converter incorporates an output filter that provides ripple/noise levels suitable for most customers. However, in some situations there are much higher requirements for low output noise and quiet supply voltages. These can be achieved by using some additional components such as extra capacitors, LC groups (PI filter) or more complex filters including common mode chokes. Vicor provides a wide range of passive components and active solutions to help our customers to meet their sophisticated design requirements. A good measurement technique is required to get repeatability and to...

Vicor is Now Shipping RoHS Compliant Products

Customers using Vicor products can decide for themselves the date that they wish to transition to RoHS compliant manufacturing processes. Whilst the European Community has established a date of 1st July 2006 for full RoHS compliance, some customers may wish to transition immediately whilst others in market areas such as Defence and Telecoms, which are generally excluded, may wish to delay transition. For our first generation VI-200 and VI-J modules Vicor has introduced new VE- part numbers that allow customers to specify RoHS compliant product. For our 2nd Generation...

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...

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...

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...
