Molded Power Inductors

By: Carlos Farnos, Dr.-Ing. Efrain Bernal / Editor: Gerhard Stelzer

Higher power requirements and miniaturization expose passives to rising temperatures, increasing the probability of thermal aging. This article explores how to select molded high-current power inductors, which are exposed to high temperatures for an extended time. The constant market demand to increase power density

Power interface module selection

Patrick Le Fèvre, Marketing and Communication Director, Ericsson

A comparison of alternative on-board power solutions is rarely at the top of the agenda for a board designer. Often designers will use a previous solution because all available resources and time

The drive towards more energy-efficient motor control in compressors and pumps

Alberto Guerra and Diego Raffo, International Rectifier

Considering that almost 60 percent of total electric energy produced worldwide is used to run motors of every size, shape and efficiency, the adoption of variable speed drives can save as much as 70 percent of energy costs by controlling the speed of the load. New energy efficiency standards for compressors an

High Power Systems

Marcus O’Sullivan Applications engineer, Power Management Group, Analog Devices

Many high power systems require the use of a hot-swap device to safely control of the inrush currents at powerup and provide fault protection. These circuits are commonly found in systems such as servers, network switches, redundant-array-of-independent-disk (RAID) storage, and other forms of communications infrastru
