Wurth Elektronik Joins Wireless Power Consortium
Würth Elektronik eiSos GmbH & Co. KG has joined the Wireless Power Consortium. The aim of the Wireless Power Consortium is to work on the development of the so-called QI standard. Ninety countries from around the world are contributing in this consortium towards a pioneering charging technology.
The QI standard (QI is pronounced "chee") is a world-wide standard for wireless charging stations of mobile electronic devices such as mobile telephones or mobile cameras. The innovation lies in the idea that charging through wired power chargers is replaced by a QI charging surface. By simply placing the device onto the charging surface it is charged through magnetic induction. The QI interface guarantees the compatibility of the devices so that every device, independent of manufacturer or brand, can be charged on the charging surface.
Current charging technologies make it impossible to charge devices of different brands from a single energy source. The Wireless Power Consortium provides a uniform solution, the QI standard.
The consortium comprises manufacturers of components, mobile user devices and network operators that work on solutions and standards.
Würth Elektronik is currently undertaking the development of special transformers and storage chokes that will be used on the primary as well as on the secondary side. The first mass-manufactured components will be available shortly. Würth Elektronik is thus one of only two manufacturers that is able to provide both sides with its components.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
