The drive to create Metadata processing server systems plus the parallel push for increased port density and triple-play (voice / video / internet) traffic handling in telecommunication systems places greater demands on power management architectures.
A new architecture is required to optimize processing real...
This paper reviews the state of the art of electric drives technology in three specific areas (a) technical requirements of high−performance ac machines control, (b) most popular electrical machines and (c) control techniques. Key development trends including the dominance of ac adjustable speed drives in new applications,...
The electronics industry is used to riding waves of growth driven by the introduction of new categories of product. This happened with the PC in the 1980s, with networking gear in the 1990s and more recently with the smartphone. Now ‘wearable electronics’ has emerged as the next potential growth market, prompted...
The rapidly growing number of electric vehicles (EVs) on the road requires more charging infrastructures to top off energy so that EVs can get back on road quickly. An EV charging station is an important element in the charging infrastructure, which supplies electric energy to the EV and provides a network connection....
As the costs for electricity generated by renewables such as wind and solar decrease and ultimately reach the electricity generation costs of conventional power plants, the demand for components with high reliability and high efficiency increases.
Since 1999, Maxwell Technologies, Inc. (Maxwell) has consistently been...
As 40 Gb fiber becomes a standard option in data centers, the challenge of connecting 40 Gb switches to existing 10 Gb equipment moves front and center. Adding further complexity, it’s clear that organizations of all sizes also need to be prepared to integrate speeds of 100/120 Gb and beyond. Custom breakout cables...
The size or power density of a power supply is a key criteria when selecting the optimum product for a given application. In applications where fans are not desirable due to noise or reliability concerns then efficiency becomes of primary concern. Power supply technology has evolved to a point where efficiencies in the...
True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field...
