The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...

The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. In this ...

Over the years, the need for increased reliability of electrical systems is no secret to those in the electrical industry. Data centers, hospitals, emergency call centers, government buildings, and ...

We recently noticed a very cool-looking series of power supply modules on a few of the Chinese deal web sites. Depending on the model, they provide a digitally-controlled voltage with metering. You ...

In this post I’m going to share my thoughts on making a simple emergency power supply system for Raspberry Pi boards. Hopefully it will be cheaper and easier to build than a commercial version because ...
