Given that harmonic content frequencies are multiples of the fundamental waveform frequency a precise estimation of the last one must be performed in order to design and calculate the total harmonic distortion (THD).
From the experimental results, it can be found that after the multiresonant control strategy is employed, the total harmonic distortion of current (THDI) decreases from 4.7% to 3.5%, and the harmonic content of 3rd, 5th, and 7th current decreases from 3.3% to 1.5%, 2.2% to 2.1%, and 1.5% to 0.9%, respectively.
Printer shows that it has a very high harmonic content due to the large value of K-Factor.
It's helpful to have many lead sheets to choose from that are already categorized according to harmonic content, such as only primaries (I, IV, V7); also with secondaries (ii, iii, vi); then secondary dominants, and then various chromatic, altered and extended chords.
Synthesizing a stepped output voltage allows reduction in harmonic content of voltage and current waveforms and eventually size of the output filter.
Harmonic content of the induction machine's air gap flux density strongly depends on geometry of the slotting, saturation, operation state and many other issues.
In solid, axisymmetric gears, the TE curve and the mesh stiffness function are typically dominated by the harmonic content at the meshing frequency.
The sparsity level is dependent on the harmonic content of a source/load and also on the fdelity of the model.
In particular, the permanent magnet AC servomotor is mostly used in the fractional slot concentrated winding whose magnetic motive force (MMF) harmonic content is very rich [6].
Figure 1 shows how you use this application to easily create a test waveform with harmonic content.
