Extensively revised and expanded to present the state-of-the-art in the field of magnetic design, this third edition presents a practical approach to transformer and inductor design and covers extensively essential topics such as the area product, Ap, and core geometry, Kg. The book provides complete information on magnetic materials and core characteristics using step-by-step design examples and presents all the key components for the design of lightweight, high-frequency aerospace transformers or low-frequency commercial transformers. Written by a specialist with more than 47 years of experience in the field, this volume covers magnetic design theory with all of the relevant formulas.
4th edition: Lots of interesting stuff. The dude really needed to label his axes. Completely unprofessional.
Use of old school CGS units are maddening. Please update for the modern SI world.
I still have no idea *why* we need an air gap. So…it skews the BH curve…so…? I still have no idea *why* we can’t use supermalloy instead of Ferrite. The numbers appppppear to be better across the board.
His design approach seems completely backwards to my way of thinking. Super weird. Not saying it’s wrong, but it really doesn’t resonate w me at all. (Not that I’ll be designing any magnetics any time soon)
There’s a few circuits here that he claims are very common but my EE Power electronics industry colleagues hadn’t even seen before. Push pull center tapped things. Quiet converters.
There’s a couple times he mixes up the term “variable” but clearly means “unit”. Pedantic, but confusing and Annoying.
No information on how transformers with dual secondaries should be layered/wound.
Clearly misleading chart in ch4 on wire gauges. He didn’t scale anything or label anything so it appears to be showing exactly opposite of the example.
Interesting stuff on shielding, Winding with foil instead of wire. Neat thing where they wrap one core with a large air gap around another core with a smaller air gap to protect against saturation
Upon first pass, I can’t get his software to do anything. Sigh.
The typesetting is an abomination and some people have strong feelings about CGS units, but there's not much else to complain about. If there could be only one book on inductor and transformer design, this is it.
