Evolving EV Battery Technology Challenges Test Systems

By Elektro-Automatik

Electric vehicle (EV) battery manufacturers and EV manufacturers are working to overcome the two major challenges facing electric vehicles: total travel distance before needing battery pack recharge and recharge time. As a result, battery pack voltages are rising to lower the weight and size of current-carrying co

The Bioenergy Imperative

Avnet Abacus, Technical Marketing Team

Today’s fossil fuels are essentially ancient solar energy trapped in dead plant matter, compressed under rocks for thousands of years, and transformed into concentrated fuels whose embodied energy can now be released through burning or other chemical processes. But what if we could radically accelerate the �

Thermoelectric Module Modeling in LTspice

Dmitry Vasilenko, Arrow Electronics

Some remote sensors are required to stay active in the field for a period longer than it’s possible for a suitably sized battery to last. In such cases, an energy harvesting system may be added to extend the operating lifetime. Available ambient energy sources can include kinetic energy present in vibrations, li

DC/DC Flyback Converter

Eleazar Falco, FAE, Würth Elektronik eiSos / Editor, Gerhard Stelzer

Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design. The flyback converter is an isolated switching power
