In recent years, there is an increasing concern about harmonic currents generated from industrial
machinery.
The following provides an overview of harmonics and measures against harmonics implemented in this
inverter.
z
Harmonics
The voltage or current whose frequency is an
integral multiple of certain standard frequency
(base frequency) is called a harmonic.
If a commercial power supply frequency of 60 Hz
(50 Hz) is the reference frequency, the harmonics
of that signal is:
x2 = 120 Hz (100 Hz),
x3 = 180 Hz (150 Hz),
and so on.
z
Reason why harmonics cause problems
As the number of harmonics increases, the wave-
form of the commercial supply has more distor-
tion. This distortion causes the malfunction of the
connected equipment or leads to abnormal heat
generation.
