Probe orientation and shielding can separate real buck-regulator output-voltage ripple from radiated switching noise.
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 ...
What causes the degradation of aluminum electrolytic capacitors in power-supply designs? What is ripple current and how can it influence capacitors in power-conversion circuits? Step-by-step ...
