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.

Squeezing more out of less

How is innovation in rechargeable lithium cells helping designers to overcome power limitations in miniature devices? Matthias Dorsch explains.

Power first and last in consumer electronics

The consumer electronics market continues to be driven by smart phones, UHD TVs, wearable devices and virtual reality (VR). But while the smartphone continues to dominate and VR appears to beapproaching a tipping point, with new devices being unveiled this year, it is the wearable market that is seeing rapid growth. It should be noted, though, that many consumer technologies are perceived as having moved beyond what is described as the ‘hype cycle’ and are no longer viewed as technical novelties or gadgets.

How innovation in rechargeable lithium cells is helping designers overcome power limitations in miniature devices

Designers of portable electronics products are familiar with the related challenges of space and weight reduction. It seems there is no limit to consumers’ desire for their devices to be thinner, lighter and sleeker. And in a product such as an earbud (or in-ear speaker), the form factor is absolutely constrained – in this case, by the size of the human ear.

ATEX and how this applies to power supplies

The acronym ATEX, derived from the French phrase "ATmosphere EXplosible”, was initially introduced in the European Union to facilitate the free movement of goods and services of equipment used in hazardous environments.The resulting ATEX Directive removed the need to test and document a product for each EU country by harmonising the way different hazardous explosive environments are classified across all industries.

How designers can take advantage of the latest product developments in intelligent power modules

The move to replace simple fixed speed motor drives with more sophisticated variable speed drives (VSDs) is gathering pace, driven by regulations such as the European Commission’s ErP (Energy related Products) Directive. As a result, manufacturers of electric motors are equipping their products with the ability to match their speed and power output to the load, providing for a reduction in average power consumption.

What is the usable power in a DC/DC converter?

The term ‘high usable power’ is widely used by the manufacturers of DC/DC converters to describe their product’s performance. Many engineers though tend to focus on the datasheet’s rated current and assume that, by selecting a more expensive, higher power converter, it will give them more derating and improved reliability.

Know where you stand

The incoming Level VI specification of the International Energy Efficiency Marking Protocol for External Power Supplies raises the bar yet again. OEMs need to understand these key specifications.

How power electronics devices are playing a central role in the modern car

Automotive manufacturers are increasingly using electronics to enhance their vehicles. The increase of the electronic content comes despite the fact that a modern vehicle is a challenging environment for silicon. In addition to the heat, vibration and grime of normal operation, drivers expect a vehicle's engine management unit and lighting to spring to life even as the vehicle's electrical power source struggles with the demands of starting an internal combustion engine – or cold cranking. That's in addition to any safety systems powered by the battery that the driver takes for granted, but must be ready to work the instant an ignition key is turned or start button is pressed.

Choosing the right A/D converter architecture and IP to meet the latest high speed wireless standards

Internet enabled mobile devices are continuing to become more prevalent in the modern world. With this proliferation of smart, connected devices – many of which are battery powered – comes a greater need for power efficient wireless transceivers. In addition to meeting stringent power specifications, RF system designers must also ensure that their devices adhere to the latest wireless standards, including Long Term Evolution (LTE) and Wi-Fi.

Design group aims to develop supplies for the low power sector

When it comes to power supplies rated at 250W and beyond targeted at medical and industrial applications, TDK Lambda claims to hold the largest market share. But tackling the much larger market for less powerful supplies has presented a problem for the company, as its product offering in this range has been determined largely by what has come out of the parent company in Japan.

Powering mobile devices with ICs is becoming easier

Whilst low power precision components have enabled rapid growth of the mobile device market, those portable products targeted at industrial, medical and military applications typically have much higher standards for reliability, run time and robustness. Much of this burden falls on the power system and its components.
