Bi-Directional DC/DC Converter Reduces Costs

A consortium led by Prodrive has developed an approach to the configuration of DC/DC converters that will reduce the cost, weight and package space associated with electric vehicle battery packs. The system is said to address the spiralling costs of energy storage by increasing the voltage available at the traction motors. To improve efficiency, electric motors require ever wider speed ranges; as speed is proportional to voltage, electric vehicles and hybrids are progressing from 300V to 600V systems. This creates a challenge because battery chemistry dictates the voltage per cell, so doubling the voltage with the same battery chemistry means doubling the number of cells, incurring cost, weight, and packaging penalties. More cells, or a switch to an alternative chemistry, may also exacerbate challenges such as thermal management, availability, environmental protection and end-of-life recycling. To address this challenge, the consortium (which also includes the University of Manchester

XMD Pressure Transmitter Measures Level And Flow

Impress Sensors & Systems has introduced the XMD range of smart differential pressure transmitters for process-industry applications. The transmitters can be used for level measurement of closed, pressurised tanks; pump and filter control; or for closed-pipe flow measurement in conjunction with an orifice plate, Venturi or nozzle. The XMD range is ideal for flow applications due to the device's ability to switch the output from a standard linear output to a square-root extraction where flow rate can be output. Target industries include chemicals, paper and pulp, petrochemicals, energy and power, food and dairy and pharmaceuticals. The XMD has a differential pressure range from 75mbar up to 2 bar and with a static over-pressure capable of 130 bar line pressures. The calibrated pressure range can also be turned down 10:1 times, which means that a 75mbar range can give a full-scale output at 7.5mbar, while still maintaining the 130 bar line pressure. A 5:1 turn-down ratio maintai

Vicote Coating Cuts Down-Time At United Biscuits

Airchannel Helps With R-22 Refrigerant Phase Out

Airchannel is helping companies comply with legislation that phases out and removes the refrigerant R-22 from their compressed-air systems. Under EU Ozone Regulation EC2037/2000, the use of virgin R-22 refrigerant will be banned from the end of this year, as it contains ozone-depleting hydrochlorofluorocarbons (HCFCs). R-22 is used in a range of industries. From January 2010 to January 2015, recycled HCFCs will be permitted but it is expected that supplies will be limited. For companies using R-22 within their compressed-air system, this could result in a significant operational headache. The likelihood of compressed-air systems using R-22 as a coolant increases significantly for equipment that is more than 10 years old. However, the legislation also represents an opportunity to help resolve two major issues facing industry - the rising cost of energy and environmental compliance. Andrew Barraclough, national sales manager for Airchannel, said: 'R-22 will be totally phased out fro
