The Ratio of the peak value divided by the r.m.s. value. With a true Sine Wave the Crest Factor is equal to the square root of 2 or 1.414
In an AC circuit, Crest Factor is the mathematical ratio of the peak to RMS values of a waveform. Crest factor is sometimes used for describing the current stress in AC mains supply wires, since for a given amount of power transferred, the RMS value, and hence the losses, become greater with increasing peak values. Crest Factor gives essentially the same information as Power Factor, and is being replaced by Power Factor in power supply technology.
The ratio of the Peak value to the RMS value of the waveform.
The ratio of the peak lamp current to average lamp operating current (RMS). The lower the current crest factor is, the gentler the ballast is on the lamp.
Ten times the logarithm to the base ten of the square of the wideband peak amplitude of a signal to the time-mean-square amplitude over a stated time period. Unit, dB (ANSI S3.20-1995: crest factor).
A way of defining the peak to mean of the signal.
The ratio of the non-linear peak current to the true RMS current. A sine wave has a crest value of 1.4142. For switchmode power supplies this ratio ranges from 2 to 4.
Ratio between the peak current value to the RMS current value.
The ratio of the maximum (crest) value of a periodic function (such as AC voltage or current) to its RMS value.
The crest factor of a waveform is equal to the peak amplitude of a waveform divided by the RMS value.
