摘要

Three potential options to implement multicore planar transformers using a printed circuit board as windings are presented. The first option utilises a distributed transformer configuration where smaller transformer elements with separate cores are interconnected to function as a single transformer. The second option has a lumped core configuration which uses multiple cores arranged to function as a monolithic core while the third is a hybrid of the first two configurations. The three transformers were designed for a 400/40 V, 1 kW, DC-DC converter application at a switching frequency of 100 kHz. The electrical and thermal characteristics of the three configurations are compared using finite-element analysis of the electromagnetic fields. The simulation results are also validated by measuring the electrical characteristics of transformers fabricated in the three configurations. The electrical and thermal characteristics of the transformers are also verified in a power converter system. Results of the comparison show that the distributed core configuration gave the best thermal characteristic while the lumped core configuration has the least winding losses.
