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.

High throughput, low power requirement

For cloud and IoT applications, there is a rising need for flexible GbE firewalls in corporate network infrastructures. With integrated Open Source and x86-based AMD Embedded G-Series SoCs, Deciso’s OPNsense firewall appliance offers double the flexibility. It enables high throughput with low power consumption making it suitable for both enterprise and IoT appliances.

How to achieve ultra-efficiency in 64-bit compute

This article describes how combining dual 64-bit/32-bit computing with targeted enhancements to memory, CPU and power-management features, the latest ARM Cortex-A35 processor delivers the efficiency needed to satisfy the future demands of fast-growing markets for entry-level mobile devices.

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.

Preview: electronica 2014

It's 50 years since electronica first opened its doors for business. Since that first event in 1964, it has grown to its current position as the leading show and conference addressing electronic components, systems and applications.

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.
