The behavior of several samples of amorphous tape-wound magnetic cores excited under sine-wave voltage conditions at 50 Hz is investigated. Measurements of the induced-voltage and the excitation-current waveforms are used to obtain the dynamic (AC) core characteristic loop consisting of the flux density versus ampere-turns and to obtain the core losses. The possibility of using wound core transformers with either silicon steel or amorphous magnetic materials is discussed. Extensive experimental results on the silicon steel and amorphous metal wound cores are presented in addition to some simulation results in order to validate the proposed procedure.

Abstract

The behavior of several samples of amorphous tape-wound magnetic cores excited under sine-wave voltage conditions at 50 Hz is investigated. Measurements of the induced-voltage and the excitation-current waveforms are used to obtain the dynamic (AC) core characteristic loop consisting of the flux density versus ampere-turns and to obtain the core losses. The possibility of using wound core transformers with either silicon steel or amorphous magnetic materials is discussed. Extensive experimental results on the silicon steel and amorphous metal wound cores are presented in addition to some simulation results in order to validate the proposed procedure.
