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 ...

Fault protection is a critical function of all power supply controllers. Nearly all applications require some kind of over-load protection. For peak current-mode controllers this is easily ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

XP Power has unveiled two single phase 1.5kW AC-DC power supplies that offer programmable constant voltage (CV) and constant current (CC) operation with analogue and digital interfaces for user ...

The article provides details on device types such as dc supplies, converters, transformers and protection devices used in ...

What do you get for the geek who has everything and likes LEDs? A tricked-out LED tester, naturally. [Dave Cook]’s deluxe model sports an LCD screen and two adjustable values: desired current and ...

One of the most versatile tools on anyone’s work bench, at least as far as electrical projects are concerned, is a power supply. Often we build our own, but after we’ve cobbled together some banana ...
