This paper has investigated iron loss characteristics of amorphous magnetic materials under the non-sinusoidal wave magnetic flux. The iron loss characteristics of amorphous magnetic materials have been compared with grain-oriented magnetic steel sheet. The measurement of the iron loss has been carried out with SST. As a result, it is found that the increase ratio of the iron loss of the amorphous magnetic material under the excitation of distorted waveforms and symmetric PWM-waveforms is less than that of the grain-oriented magnetic steel sheet. On the other hand, it is found that the increase ratio of the iron loss of the amorphous magnetic material under the excitation of asymmetric PWM-waveforms is larger than that of the grain-oriented magnetic steel sheet.
