| Summary, etc. | REVIEWS “I recommend for serious power-electronics engineers, to obtain a copy of this excellent book, if for no other reason than to be current on planar and integrated magnetics, to have the winding proximity- and skin-effect loss theory worked out in one place for design, and on the advantageous incorporation of variable inductance in circuit design.” (How2Power.com, October 2014) |
