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.

How to use a clamp meter to measure inrush current

Inrush current effect is common in electric motors. Sometimes, in case of ill-designed electrical wiring systems, switching on the motor may activate the fuse. It is caused by the inrush current – when the motor starts, it takes the current much higher than the regular operating current or than the motor which is in a stable working mode. The effect is rather short-lasting. For example, for a 3-phase motor it lasts 75 to 150ms, but the current increases by 500% to 1200%, which may cause serious problems and malfunctions. Besides, the measurement of the inrush current is required in the maintenance of electric motors.

The hypervisor advantage

Operating Systems (OSs) like Linux and Android are widely used in embedded systems but being large, complex and inevitably containing numerous flaws once compromised, an attacker can violate the security and take control of the whole system.

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.
