New Electronics strives to bring you all the latest technology news from the Power sector. Advances in electronics are often fast-paced and innovative, so we know that as a design engineer you want to be kept up-to-date with current developments.

Below is a comprehensive list of all the latest electronics technology news from New Electronics.

Digital dilemma

As the amount of data soars and computational power accelerates, data centres are set to have a bigger carbon footprint than the aviation industry. What can be done to address this?

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.

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.

RS-485 transceivers need protection against large over-voltages

Robustness and reliability have made RS-485 an industrial workhorse. A minimum differential signal swing of 1.5V and reliable operation over common-mode voltages ranging from -7V to +12V have catapulted its deployment. Initially used as a communication network in laboratory instrumentation, RS-485 can be found in applications ranging from building automation to traffic monitoring systems.

Network transformation

Of all the new semiconductor device technologies that have been introduced over the past few years, gallium nitride (GaN) is arguably generating the most far-reaching effect across a number of different applications areas.

Beyond the threshold

Given the massive spikes in power consumption incurred by microprocessors and memory when they ramp up to top speed, it is no surprise that much of the attention in circuit design is aimed at trying to find ways to keep digital power under control.

Analysing the energy storage challenge

Users of battery powered consumer electronic devices usually have one thing in mind; how long will it last before the battery needs to be recharged. Depending on the device and how it’s used, that could be less than a day.

Europe's largest construction project: Crossrail

Work on Crossrail, or the Elizabeth Line, Europe’s largest construction project started eight years ago. A complex engineering project, it runs 100km from Reading and Heathrow in the west, underground across London to Shenfield and Abbey Wood in the east. The first rail services running through central London are due to start at the end of 2018 and, once complete, the new line is expected to be able to handle more than 200million passenger journeys a year.

Avoiding power brownouts in high availability systems

For scalable capacity and modularity, systems such as servers, industrial computers, enterprise data storage and network routers are built with slots to accommodate multiple processing and I/O cards. To ensure high availability and uptime, hot-plug capability is required so that the entire system is not powered down for card insertion and removal.

ICs to bring longer battery life to portable devices

As users demand more functionality and longer runtime from their devices, the need to understand what is consuming a battery’s charge becomes more important. Hardware developers can use this information to track energy used in different conditions, while software developers can adjust their coding decisions to improve efficiency. Meanwhile, operating systems can monitor how processes use power and consumers can see how their battery is used and realise possible actions to take for longer runtime. The knowledge gained from measuring accurately how a product uses the battery leads to an understanding of the design trade-offs – turning knowledge into power.
