THD - Coggle Diagram
THD
Odd Harmonic
Symmetry of waveform
-
Odd harmonic preserve this symmetry, while even harmonic would disrupt it, so in systems that naturaly tend to have symmetrical signal (like AC power systems), even harmonic are typically not present or are very small
-
design and Filtering
-
most electrical system re designed to minimize even harmonic because they tend to introduce more distortion than odd harmonic
-
-
What Are Harmonics?
Harmonics are additional frequency components that are Integer multiples of the fundamental frequency.
Formula
For voltage or current, the THD is given by:
