Cascade multi-level inverter design

Inverter design is one of the outstanding issues in the field of power electronics. One of the most important studies in inverter design has been the multi-level topology. used in many designs because of its working ability in high power and high efficiency alternative energy sources.

Thermal simulation of electronics operating in a rugged or hostile environment

There the environment often dictates how device should be cooled and forces engineers to make design choices they might ordinarily avoid.

Advanced components for e-mobility leads to a sustainable future

In electric vehicles, the drive system generally consists of electric motor, inverter, battery and charger. For the electric drive to propel the vehicle, the motor must be fed with an alternating current, which is supplied by the inverter. The inverter converts the direct current from the battery to an alternating current.

Intelligent charging design for energy-saving applications

Most portable electronic devices are developed for high efficiency, low power consumption and reliability. This requires that their batteries offer a long life and high efficiency, too.

Using signal level attenuation and self-biasing to create translation circuits with fewer external components

Each type of clock logic features a different common-mode voltage and swing level. Because of these differences, clock logic translation needs to be implemented between the driver and receiver sides in system design.

Installing Industry 4.0 processes through digital retrofitting

An important element of Industry 4.0 is the ability to apply digitisation to the production environment by adding more intelligence into existing processes.

Building a reliable and robust autonomous system

Fully-autonomous Level-4 and Level-5 vehicles are getting a lot of attention at the moment, with some test fleets already running in the US. However, the more immediate promise of Level 2+ and Level-3 automated driving solutions are far more realistic because of the price and technical advancements.

Q&A with Stephen Currier, UK Managing Director of Eaton, who discusses non-compliant lighting products and their effect on the market

There is undoubtedly a large – and growing – number of non-compliant products currently for sale in the UK. And while our reaction may be to point the finger of blame at Internet trading, poor product is also being sold through otherwise reputable electrical wholesale businesses.

0-5V or 4-20mA to 0-5V signal converter-analogue ınput modules

A project involving thirteen analogue input modules and seven analogue output modules for 5V microcontroller’s ADC/DAC channels. In this part, we’ll cover the twelfth and thirteenth analogue input modules, i.e. modules 1 and 2 for a 0-5V or 4-20mA to 0-5V signal converter.

In-mould electronics and conductive inks

Conductive inks have proven to be a wonderfully adaptive technology, recently rejuvenated, finding many new applications when old markets struggled and declined.
