Fundamentals of a.c. signals

Abstract

Waveform analysis is widely applied to measurement and computational analysis of B-H characteristics, magnetostriction and losses of electrical steels and other soft magnetic materials. The fundamentals of waveform analysis relevant to these applications are presented in this chapter for the benefit of readers who might be less familiar with the topic. The chapter gives a brief introduction to waveform analysis before focusing on the occurrence and common applications related to magnetic parameters particularly important in the application of soft magnetic materials in power devices.
