Oscilloscope probing techniques for measuring power supply ripple

When evaluating a power supply, engineers need to check the amount of ripple and noise present in the output voltage and the response of the output to load transients. Careful attention to measurement techniques using an oscilloscope probe, and applying suitable conditions for transient tests, are essential to ensure an accurate assessment.

AC-DC efficiency measurements need to include power factor

Power converter designers compete to minimise losses, chasing the last decimal points of efficiency, η, the ratio of output to input power. But when it comes to calculating efficiency in AC-DC power supplies mistakes are often made as a result of omitting or improperly measuring power factor, which is why it is important for designers to understand power factor basics and how to incorporate it.
