A planar integrated inductor-capacitor-transformer structure is described f
or use in series resonant converters, The construction and design of the st
ructure is described, and design equations derived. The structure is analyz
ed from a volumetric point of view and some of the limits of the technology
are discussed, Experimental results of an LCT structure for a 5 kVA conver
ter at 25 kHz are presented.
