Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests 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, ...
FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

This dummy-load circuit has been in use at Maxim for more than 10 years (see the figure). It's useful for testing power supplies and power amplifiers as well as drivers for LEDs, relays, and solenoids ...
Abstract: Cascaded converters need to be tightly regulated to have better system performance and faster dynamic response. One of the major issues in cascaded converters is that they behaves as a ...
I needed a quick, cheap and simple method of testing the capacity of a rather large batch of small Li-ion cells to bin them and assemble a larger battery. The testers I obtained to measure the actual ...
The 8-channel lithium-ion battery testing system is designed for high-demand uses, offering reliable charging control and temperature checks. The multichannel lithium ion battery testing system ...
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 ...
