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 ...

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 ...

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 ...

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, ...

Abstract: In this paper, a constant current and constant voltage charging circuit through MPPT method, and its stability analysis is proposed. The input part is a solar cell array, the converter uses ...

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 ...

This code supports Application Note AN1138: A Digital Constant Current Power LED Driver, using the PIC12HV615? an 8-pin, PIC microcontroller (MCU) with many integrated analog features. The LED driver ...

Abstract: In this paper, a LCC-WPT behaving as a current source in certain condition and its optimization design method was investigated. The formula of output current has been deduced from wave base ...
