International Rectifier has introduced an integrated power module said to simplify the design of low-power variable speed drives. The IRAMS10UP60 PlugNDrive module incorporates a three-phase inverter power stage with gate drivers and auxiliary circuitry. It is rated at 10A and designed for 400—750W motors used in applications such as air conditioners and domestic appliances.

• The National Physical Laboratory (NPL) is asking for suggestions from industry on the content of a £8m DTI-sponsored research programme into materials performance, that is due to start next April. The aim is develop projects on measurement techniques, test methods and predictive tools that are relevant to the current and future needs of UK industry. Industrial collaborations are expected to take the value of the three-year programme to £12m. Details on (44) 0208 943 6701.

Sanken Electric has developed three high-current inverter modules for appliance applications which are being unveiled by its subsidiary, Allegro Microsystems, at the PCIM show in Nuremberg this month. The modules, which are said to provide energy savings, will be manufactured on a mass-production line that also makes modules for other markets, thus allowing the production of semi-custom devices.
