Design and Analysis of a Fully-integrated Planar Transformer for LCLC Resonant Converters

The isolated LCLC resonant converter needs five discrete passive components including two capacitors, two inductors and a transformer. In this paper, to cut down the number of components of this converter, a new design for a high-frequency transformer is proposed which integrates all the five magnetic and capacitive components in only a single magnetic device. The series capacitor and inductor are...
