A benchtop power supply is a key thing to have for any aspiring electronics hacker. While you can always buy one, plenty of us have old computer PSUs lying around that could do a fine job themselves. ...

Although variable dc power supplies might appear to be relatively simple instruments, engineers rely on them to deliver stable, precise, and clean voltages and currents, regardless of the load. To ...

The purpose of the project is to build a power supply that is capable of supplying a variable voltage output from 1.5V to 12V. The purpose of the project is to build a power supply that is capable of ...

This current-limiting circuit, shown in this example as part of a small bench power supply, could in principle be used in conjunction with any dual-rail current source. The part of the circuit to the ...

Bench power supplies come in all shapes and sizes. Some fall into the general-purpose category, and others are very application-specific. Some only have a single output, while others offer multiple ...
