Useful RMS Waveform Equation Calculations Released

Posted: 11 February, 2007

We have released a new design document which gives the derived RMS and average values of some current waveforms commonly found in switching power converters.

When designing power stages, as well as the peak currents, it is important to know what the average and RMS values of current waveforms are in order to calculate the expected heat dissipation.

The document gives you the derived equations for most of the waveforms you would encounter in switching power supplies.

Example RMS and Average Current Equations

We have lots more useful material available in our technical resource section.
