A manufacturer of power semiconductors and ICs for energy efficiency, power management, medical, transportation and consumer applications, IXYS, has announced the IXRD1004 - High Power Two-Phase Digital Power Factor Correction (PFC) reference design. It is based on Zilog’s 8-bit Z8F6481 microcontroller, a member of the Z8 Encore! XP F6482 series of microcontrollers, and IXYS power transistors and rectifiers.

The 2016 Super12 components from Vishay have been added to the Farnell element14 product portfolio for same-day shipping. The group of components highlights Vishay’s most innovative semiconductor and passive components including resistors, capacitors, diodes and more for applications such as consumer electronics, audio amplifiers, industrial PCs and controls, and home automation.

A leading coil processing equipment manufacturer has introduced variable speed drives from Control Techniques, an Emerson business. Athader, based near San Sebastian in northern Spain, manufactures coil processing lines, mainly slitting lines and levelling and cut-to-length lines for steel, stainless steel and aluminium material. Equipment manufactured by the company, which is part of the Bradbury Group, is destined for customers that include ste...

The old rules don't necessarily apply when building electronic components out of two-dimensional materials, according to scientists at Rice University.The Rice lab of theoretical physicist Boris Yakobson analysed hybrids that put 2D materials like graphene and boron nitride side by side to see what happens at the border. They found that the electronic characteristics of such "co-planar" hybrids differ from bulkier components.

Ericsson Power Modules has announced the BMR458, a 3rd gen 3E quarter-brick advanced bus converter that delivers industry-leading performance to system architects developing equipment for ICT applications, including datacomms and server and storage systems.

Designed to deliver a low forward-voltage drop in a small form factor while maintaining low reverse-current leakage, the SBRT3M40P1 Trench Super Barrier Rectifier (SBR) has been introduced by Diodes Incorporated. This capability addresses requirements for input bridge rectifiers in SSL applications focused on 12VAC LED retrofit lamps, which provide a more efficient and longer life alternative to popular MR16 halogen bulbs.

A graphene-based electrical nano-device has been created which could substantially increase the energy efficiency of fossil fuel-powered cars. The nano-device, known as a 'ballistic rectifier', is able to convert heat which would otherwise be wasted from the car exhaust and engine body into a useable electrical current. Parts of car exhausts can reach temperatures of 600 degrees Celsius. The recovered energy can then be used to power additional a...

STMicroelectronics has announced advanced high-efficiency power semiconductors for EVs & HEVs with a timetable for qualification to the AEC-Q101 automotive standard. In EVs and HEVs, where better electrical efficiency means greater mileage, ST’s latest SiC technology enables auto makers to create vehicles that travel further, recharge faster and fit better into owners’ lives.

Linear Technology Corporation announces the availability of a low loss 3-phase suitable diode bridge rectifier reference design, demonstrated on evaluation board DC2465. Conventional 3-phase rectifiers employ six diodes, but the diodes drop voltage and dissipate significant power at just a few amperes of load current. This requires costly heat sinking and active cooling solutions that complicate thermal design and increase solution size.

An increased range of HY Electronics rectifier diodes and bridge rectifiers is now available to order from JPR Electronics. The extensive HY product range includes rectifier diodes, bridge rectifiers, Schottky barrier rectifiers, power mosfets, fast recovery Epitaxy diodes, 3-phase rectifiers, transient voltage suppressors, LED driver modules (CLD) and IGBT modules.
