Total Harmonic Distortion: Theory and Practice
19 déc 2018 · This application note discusses Total Harmonic Distortion (THD) which shares characteristics with Electrochemical Impedance Spectroscopy |
The THD of a pure sine waveform with no higher harmonics, such as the ideal voltage supply, is 0%.
A value of THD greater than zero means the sine waveform has become distorted.
THD is often given as a percentage, such as 5% or 50%.
THD can be measured for current and voltage.
What is the total harmonic distortion?
The total harmonic distortion (THD or THDi) is a measurement of the harmonic distortion present in a signal and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency.
What is a good value of THD?
The THD value in voltage is typically 1% to less than 10%.
As for the current, the value may exceed 100% when there are a lot of harmonics.
