Power

Power electronics is a key element in the world of electronic design and engineering and electronic engineers need to have a thorough understanding of this area if they’re going to create successful products.

In this section, New Electronics keeps designers up to date with the latest developments in the power electronics market – everything from DC/DC converters to IGBTs to battery technology. In fact, New Electronics covers any power product that can go on a PCB.

Can a transient effect rescue silicon power scaling?

The war with semiconductor physics claimed another victim at the end of August when GlobalFoundries decided it could no longer afford to continue work on a 7nm finFET process, or its successors, despite the efforts of teams that came originally from AMD and IBM. With deeper pockets, Intel, Samsung and TSMC are continuing but at some point even they will either run out of nanometres or the belief that they will find enough customers to pay for increasingly expensive wafers that may not justify the scaling benefit they achieve.

Will the attractions of embedded FPGA overcome traditional cost objections and finally see accelerated growth?

Twenty years ago, it looked like a concept that was ready for primetime: putting programmable logic inside ASICs and SoCs. At the time, the move seemed inevitable. ASIC mask prices were rising fast, driven by the need to pull more and more from a bag of optical tricks to keep Moore’s Law on track. The cost of respins alone seemed enough to persuade designers to leave some reprogrammable “sewing kits” in their SoCs to let them iron out bugs after tapeout instead of committing tens of thousands of dollars more to the project to get some new masks.

Measuring battery life

Poor battery life is affecting the take-up of too many devices. How can power be analysed in enough detail to ensure products live up to consumer expectations?

Design a switch mode power supply using an isolated flyback topology

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also investigates the design of a single output supply utilising flyback topology and provides a sample design using readily available parts and components.

A better approach to engineering study?

While Hereford University of Technology and Engineering will be the first new university to open in Britain in 30 years, crucially it’s looking to provide a dramatically different approach to studying engineering.

Flash storage in networking infrastructure needs to focus on reliability, quality and data retentions

The infrastructure to support and grow connectivity is constantly evolving, and encompasses telecommunications, data communications and data centres. The processing and storage applications in that infrastructure stretches from base stations to subscriber lines, through a hierarchy of routers and switches. As the amount of digital traffic continues to expand, the need for fast and reliable storage only increases.

The best way to generate a negative voltage for your system

Modern active components, such as A/D and D/A converters and operational amplifiers, typically don’t require a negative supply voltage. Op amps in particular are available with rail-to-rail inputs and outputs, and in most cases, input and output voltage can swing to close enough to GND.
