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.

Analogue AI feels the power

Deep learning has an energy problem. Model sizes have been spiralling up, and doing so at an increasing rate as users exploit cloud servers armed with graphics processing units to crunch the numbers.

Over-the-air charging gets real

?The ability to send an electric current through the air, from one location to another, may not be a new idea but it has certainly taxed the minds of engineers for many years – that is the ability to transmit power wherever it is required and without the need for wires.

Going virtual

Could Virtual Reality replace physical travel helping the leisure and tourism industry to reinvent itself post Covid-19?

Truck platooning

All around the country, at all times of the day, 365 days a year, commercial vehicles are on the move.

A clearer roadmap

There are four trends now shaping the automotive market and in a report published in 2016 by McKinsey & Company (“Automotive revolution – perspective towards 2030”) these were identified as autonomy, connectivity, electrification and diverse mobility.

Reshaping the automotive industry

As the demand for electric vehicles has accelerated, so automotive manufacturers and original equipment manufacturers (OEM) are adapting their business strategies as they look to engage with this market.

Motor protection breakers as a form of effective drive protection

Electric drives require effective protection against overloads and short circuits. Both phenomena cause motor disruption and create a risk of damage to the motor. This could lead to a potentially dangerous situation for people in contact with the devices. Modern motor breakers are the current remedy for both threats, and are a part of multi-level drive protection systems together with circuit breakers, RCD breakers, contactors, detectors (sensors) of phase failure and phase sequence, and undervoltage protection.

A partnership in design

Although most electronics engineers understand the principles of an AC to DC power supply (PSU) and could probably design one to work, it takes specialist knowledge and skills to fully optimise it for cost, size and performance.

A touch-free world

Optical sensors are being used to help create a safer, touch-free world as a result of COVID, as Gabriele Fulco explains to New Electronics.

A supply chain in flux

In the coming years, Tier 1 automotive suppliers have an enormous opportunity with the development of autonomous vehicles (AVs) but there are challenges - the whole supply chain is being disrupted by new participants and new technologies.

Advances in user interface design

Ian Crosby from touchscreen manufacturer Zytronic, looks at the considerations that need to be taken into account when a product designer is planning a device that has a touch interface.

Hardware progress

A DVCon Europe 2019 conference paper, jointly authored by Renesas and OneSpin Solutions, considered innovative chip safety analysis. In this article Jörg Grosse and Sergio Marchese discuss its findings.

Converters for photovoltaic panels

In recent years, we have witnessed a growing interest in “green energy”. Numerous applications are offered that make it possible to obtain energy from freely available sources, among which photovoltaic panel installations are the most popular ones. Their prices have become so affordable that they are oftentimes installed even in small summer houses. When building such systems, it is important to understand the specific nature of the energy source – a photovoltaic panel or a turbine. One should also bear in mind the challenges faced by the manufacturers of devices powered from such sources.

Hardware progress

In today’s vehicles, according to AUDI, microelectronics enable over 80% of vehicle innovation and high-end cars may contain more than 100 electronic control units (ECUs) controlling both safety-critical and entertainment functions, as well as implementing advanced driver-assistance systems (ADAS).
