Diodes Incorporated has announced the first devices in a family of Super Barrier Rectifiers (SBR®) designed for automotive applications. With a lower forward voltage drop, improved avalanche rating and higher safe operating area (SOA) than alternative Schottky or ultra-fast diode alternatives, these rugged rectifiers enable automotive designers to increase the reliability of motor control, display panel and LED lighting circuits.

The new ROBA-multiswitch, developed for switching safety brakes quickly, is capable of emitting a constantly controlled DC voltage independent of the mains voltage. This means that complex adaptation of magnetic coils to varying input voltages becomes unnecessary. Overexcitation on switch-on ensures that the connected brakes release extremely quickly.

The new RT 20 series of standard industrial duty UPS systems is announced by Borri Power Systems Limited.

One of the world’s most respected manufacturers of Uninterruptible Power Systems (UPS), BORRI S.p.A, will now have representation in the UK following the setting up of BORRI UK, an exclusive distributor of BORRI products. Nottingham based BORRI UK has a nationwide team of sales and factory-trained technical personnel who will focus on providing resellers and end users with first-rate customer support.

At the fifth IET International Conference on Power Electronics, Machines and Drives (PEMD 2010), TDK-Lambda, one of the world’s leading experts in the development and manufacture of power supplies, is presenting a ground-breaking paper entitled: “Reduced Synchronous-Rectifier Losses in Off-Line Resonant Converters using the LCC Topology.”

International Rectifier today introduced the IR11672A SmartRectifier IC with advanced Minimum On Time (MOT) protection circuitry for energy-efficient AC-DC power converters for laptops, LCD and PDP televisions, game consoles, and server and telecom Switch Mode Power Supplies (SMPS).

Emerson Network Power today launched the HPS3000, its highest bulk front-end distributed power supply. The 3,000 W HPS3000 offers enterprise networking professionals and telecommunications system integrators a compact, high-density power solution and a cost-effective alternative to ac-dc rectifiers and other rack-based power options.

Vishay Intertechnology and Digi-Key Corporation have announced that Vishay's portfolio of semiconductor products, which includes MOSFETs, diodes, rectifiers, RF transistors, optoelectronics, and selected ICs, is now available from Digi-Key. With this major enhancement to its line card, Digi-Key now carries the full range of Vishay semiconductor and passive components.

TDI has developed LiquaCore™ (patent pending) power management technology which employs liquid cooling from a modular and scalable architecture. The technology uses a cold plate to wrap the electronics with cooling liquid in a sealed package that enables efficient management of waste heat at very high power densities. The cooling liquid employed is either water or a mixture of water and ethylene glycol (anti-freeze). By using standard converter...

Vishay Intertechnology has announced a series of enhanced high-current-density PowerBridge rectifiers with current ratings of 10A to 25A and maximum peak reverse voltage ratings of 600V to 1000V. Compared to larger-size bridge rectifiers on the market, the advanced thermal construction of the PowerBridge devices allows heat to dissipate more efficiently. The PowerBridge rectifiers are thus able to provide the same power ratings as larger package...
