The buzz about crest factor in power supply design and test

Tektronix Experts's blog picture

Among the several measurement parameters used to assess power quality, crest factor (not to be confused with power factor) often garners attention. Crest factor is the ratio of the peak amplitude (current, voltage etc.) to the RMS (root mean square) value of the amplitude of a waveform.

C = |A|PEAK / ARMS

So how exactly does crest factor manifest itself in real life?

Power factor and compliance with ENERGY STAR and IEC 61000-3-2

Tektronix Experts's blog picture

Mathematically, power factor can be expressed as the following:

Power Factor = Real Power (Watts) / Apparent Power (VA)

Looks harmless, doesn’t it! So, why is this an important ENERGY STAR and IEC 61000-3-2 requirement?
