The purpose of this project is to control the current across a load by using pulse width modulation for maximum power efficiency while being constructed on a breadboard. The project accommodates 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 ...

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 ...

Power supply manufacturers sometimes hear from customers with unfortunate dilemmas, such as, “I need to operate the power supply outside its rated voltage range.” Or, “What happens if I exceed my ...
