Book Synopsis
Power magnetic component design remains a complicated mystery to many, yet need not be. This book is not a rehash of existing textbook material. It presents new, logical, and simplified ways of thinking about magnetics. It develops new methods for determining maximum core power density. It shows why core materials each have an optimum ripple factor of the current waveform in a winding for maximum power density. An improved wire packing factor versus wire size formula is developed from geometry as is toroid winding length. Multifilar design is developed.
Eddy-current effects are based on the results of Dowell's equation. Geometric winding constraints are applied to its layer parameter to plot loci of constant-winding-area and constant bundle strands. Operating-points of interest along these loci are derived, with design formulas.
The last chapter gives design procedures, power sizing over an input range, and examples.
