This work had its roots in the belief that a deeper understanding of the electromagnetic power conditioning mechanism is necessary in order to keep pace with the trend towards an ever increasing frequency-power product in switchmode converter technology. Circuit design with the objective of keeping skin effect and proximity effect tosses a minimum has been identified as a major criterion in the optimisation of high frequency converters. Overall, four major contributions emerged from this effort: firstly, energy flow modelling as a means of gaining insight into the mechanism of power conditioning; secondly, an algorithm has been devised to analyse structural impedances; thirdly, a new set of equations have been derived to model skin and proximity effect losses in magnetic components; and lastly, an experimental method has been devised to measure the ac resistance of magnetic components.
