The heart of the device that [Kerry] designed is based on 6 power MOSFETs, a few operational amplifiers and an Arduino compatible ATmega328p microcontroller. Sense resistors are used to measure how ...

How do you deliver constant power when the load impedance isn't constant? That problem arises, for example, in trying to maintain a warm LCD display on an outdoor gas pump in cold climates. As the ...

Some projects are both educational and useful. We believe that [Jasper’s] Arduino based electronic load is one of those project. [Jasper’s] electronic load can not only act as a constant current load, ...

It is crucial to comprehend how the electric load reacts to changes in the supply voltage, especially when voltage reduction is now being utilized more often by utilities as means to reduce electric ...

This project is made out of few junkbox parts and builds a useful constant current load for switch mode power supply, battery testing, and other applications. A dummy load is traditionally a big ...

When reviewing power-supply specification requirements and supporting design proposals, we often see the minimum load identified as 0 A loading. Although not an issue in and of itself, this no-load ...

Having been around since the early 1960s, electronic loads evolved out of the need to emulate real world applications in testing power supplies as well as batteries, and now fuel cells. The first ...
