  • Abstract
    The core noise was measured for the half-wave push-pull magnetic amplifiers using various ferromagnetic materials as functions of the number of laminations of a stacked ring core and ac supply frequency. A statistical model of the core noise is proposed. It was deduced that the mean number of magnetic elementary regions associated with the core noise is proportional to values ranging from f to f^{3/5} , where f is the ac frequency.
