Abstract
The estimation of magnetic losses in a non-oriented grains FeSi sheet by a time-dependent method is used in the paper for underlining the influence of each harmonic initial phase. The initial phase of the first harmonic, usually indicated by a power analyzer to be zero, is very important for the signal shape, the losses being dependent on this parameter. The paper proves that THD and the harmonic amplitudes of the magnetic flux density are not sufficient for the magnetic losses predetermination in distorted regime, the initial phases of the harmonics being of great importance for any computation involving a truncated Fourier series.
