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.

Living with lithium

Batteries play a key role in a range of applications and are used in medical devices for increased safety of operation and for having the freedom to move instruments around in hospitals.

The road to zero

As the demand for EVs accelerates so the need for an effective power charging infrastructure becomes critical.

It’s do or die for diesel

Everyone agrees that the traditional internal combustion engine which runs on carbon fuel is not sustainable and vehicle manufacturers have been looking for alternatives for decades.

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.

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.

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.

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.

All electric aviation

Cutting carbon emissions could form an essential part of post-Covid-19 recovery plans for the aviation sector. Could that help to accelerate the development of all-electric aviation?

Battery health & safety

Lithium-ion batteries are popular because they have a number of important advantages.They’re lighter when compared to other types of rechargeable battery and lithium, being highly reactive, can store a lot of energy in its atomic bonds.

Squeezing every drop!

The Internet of Things (IoT), Industry 4.0, digital health and greater prevalence of wearable electronics all rely heavily on the use of sensing devices that it simply won’t be practical to plug into a mains socket.

Wireless Charging Continues to Drive Forwards

So, why isn't every consumer device charged wirelessly? Charging cables and power leads have always proved to be a nuisance, and are something that the industry could quite easily eliminate. Well, there are now moves underway to do this.

The power to change

During the heatwaves that hit Europe and North America over the summer, users were posting to Twitter and social media sites how their smartphones were suffering from heat exhaustion.
