Abstract
Acoustic noise in a molybdenum permalloy powder (MPP) core transformer is analyzed and modeled as vibration induced by magnetostriction. The model indicates the relationship between physical parameters, primary and secondary waveforms, and the magnetostriction coefficient and their effects on acoustic output.
