Keeping operations running up to speed is at the heart of today’s business world. In a 24/7 environment, there’s no room for error, and giving your customers the most bang for their buck is at the ...

This document teaches the users to determine the characteristics of step-down DC-DC (buck) switched mode power supply through understanding and exploring its voltage and current waveforms. Both the ...

The circuit drawn pertains to a regular industrial UPS (Uninterruptible Power Supply), which shows how the batteries take control during an outage in electrical supply or variation beyond the normal ...

Building a custom PC is an exciting and fulfilling endeavor. However, it can quickly become daunting when selecting a suitable power supply unit or PSU, a vital yet commonly underestimated component.

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

Switch-mode regulators include the buck (step-down) and the boost (step-up), forward and flyback topologies, as well as the SEPIC, hysteretic and multiphase converters. Two basic IC topologies are ...

The power supply unit (PSU) is one of the PC components that we tend to take for granted. It sits in the case with a bunch of wires sticking out of it, and maybe once in a while we blow some air blown ...

The PC power supply has been a standard of the junk box for the last couple of decades, and will probably continue to be for the foreseeable future. A product that is often built to a very high ...

Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

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 ...

If your computer is behaving strangely or randomly crashing, it can be hard to nail down the culprit. And as much as you don't want to believe it's the problem, testing your power supply should be ...
