摘要: Abstract : Among the challenging unsolved technical problems that have plagued minds of scientist and engineers throughout 20th 21st century is development a quantifiable model to accurately estimate or explain Core Power Losses (CPL). Theoretical advances in magnets led many proposals, but as these models were experimentally examined, they quickly lost their validation. Many current use manufacturer's material estimates form limited curve fitted equations. These equations are only valid for specific waveform over specified range. Unless designers same conditions used determine equations, lose precision. The scope this thesis compare several evaluate them using experimental data. validity some term components will also be investigated.
