There are a number of reasons why measuring the output ripple in switching regulators is such an important and delicate task. It is possible to receive erroneous readings while trying to measure this ...

Making ripple measurements has traditionally been using an oscilloscope. For a number of technical reasons, an oscilloscope, in general, is not necessarily the best choice for measuring ripple. These ...

We all know how to block the DC offset of an AC signal — that just requires putting a capacitor in series, right? But what if the AC signal doesn’t alternate very often? In that case, things get a ...

Specify current ripple ratio to optimize a power supply , relying on extrapolation rather than intuition to choose the right off-the-shelf inductor for your application. An inductor is designed for ...
