The circuit diagram and working of Variable Voltage Power Supply from Fixed Voltage Regulator is explained in detailed manner. The voltage regulator is used to offer fixed voltage at the output ...

This article discusses controlling a voltage regulator using a digital potentiometer with pushbutton controls, the DS1809, which give a “human interface” to the control of the voltage regulator. This ...

Switch-mode power supplies are ubiquitous. Standard off-the-shelf modules in a consistent range of form factors available from multiple manufacturers. Globalized manufacturing and trade has turned ...

Once upon a time, building yourself a power supply required sourcing all manner of components, from transformers to transistors, knobs, and indicators. These days, everything’s a bit more integrated ...

For the PDF version of this article, click here. The goal of this project was to design and build an efficient power supply system whose output voltage (V OUT) could be accurately set to a digitally ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...
