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 ...

It is a common belief that multi-layer ceramic capacitors (MLCCs) or DC power supply circuits cause audible noise, but that’s not true. The noise is generated by the PCB, not by the components. The ...

One of two uninterruptible power supply (UPS) systems had become “interrupted,” and no one onsite knew where the bypass ...

A steady supply of voltage is important in industrial and commercial applications to maintain equipment performance, product quality, and safety, while also minimizing downtime. Voltage sags (where ...

[Kerry Wong] isn’t afraid to get his hands dirty, and is always more than willing to open things up and see what makes them tick. This time, he reviews and tears down the Topshak LW-3010EC ...

DC motors come in many forms, but they all have the same job: turning electrical energy (DC) into mechanical energy. Although DC motors have a common operating principle, many applications—including ...

Consumer electronics, industrial, robotics, medical, and military applications all frequently use an AC/DC power supply, also referred to as AC/DC converter. An accurate design of the power supply ...
