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 ...

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 ...

Most electrical engineers believe they have a good understanding of power supplies because they are relatively simple, single-function DC devices designed to output controlled voltages. However, there ...

When your bench supply's capacitors are all charged up with nowhere for that charge to go, an active down-programmer is a handy technique that brings rise and fall times back into a viable range. Here ...

Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...
