No electricity provider in the world can guarantee an electrical supply that is free from voltage and frequency variations. The possibility of faults occurring in user installations or in the public ...

We can often find useful or interesting things in old items. Some items can become invaluable under the right circumstances! In this post, I am talking about an older adjustable step-up dc 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 ...

This file type includes high resolution graphics and schematics when applicable. Let’s face it: Some lucky folks don’t have to worry too much about power conversion. Just plug the board into the ...

It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...

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 ...

As manufacturers of all types of mechanical equipment work toward using energy efficiently, regenerative power technology has taken a major role in reducing operating costs. Power regeneration is the ...
