How accuracy is defined in DC programmable power supplies How and why the power supply experiences voltage output errors How to wire test leads and sense leads for accurate measurements When testing ...

Making a dc voltage from an ac source means you will have to rectify the ac voltage to get a dc bus. One difference compared to a dc-dc converter is that you can use a linear power supply with an ac ...

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 ...

Permanent magnet DC (PMDC) motors offer smaller solution size and increased efficiency in applications such as portable vacuums and cordless electric power tools. When designing an isolated power ...

A new way to build your own DC power supply with more control over design choices and how the system is put together.

[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 ...
