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 ...

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 ...

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 ...

Damage to a relay contact after cyclic current loading. A better understanding of inverter reliability will help boost performance and reduce costs. Image: Fraunhofer IMWS. Inverters are critical to ...

The most important thing to keep in mind when operating the server yourself is the power supply. Even if applications and networks are running normally, it does not make sense to power down essential ...

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 ...

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 ...

Before we go forward and run some of the tests that we are going to see hereinafter, let us check a few of the symptoms to understand if those tests are worth doing. We have mentioned some symptoms ...

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 ...
