Improved loss determination for planar integrated power passive modules

Integration of passive components, such as the planar L-C-T (Inductor-Capacitor-Transformer) technology has been the subject of research over the last few years and has been proven to be viable at high frequencies. Research to determine the volumetric limits of these structures has shown that better loss modeling is required before any volume reduction and optimization is possible. A comprehensive, yet simple loss model for the planar integrated L-L-C-T is presented and verified using experimental case studies. The loss model takes non-sinusoidal core excitation losses, both skin- and proximity-effect conductor losses and dielectric losses into account.
