A novel integrated EMI filter structure is proposed in this paper, based on the flexible PCB integrated L-C winding. By employing this integrated L-C structure, CM inductors, DM inductors and CM capacitors are integrated in a single unit. By compare with the planar PCB winding that used in previously proposed method for integrated EMI filters, we found that flexible PCB winding need less length, which...
In this paper, a transformer structure integrating three resonant tank components Cs, Ls, and Lp of the LLC resonant converter is proposed and implemented. For the structure, the analysis and calculation of Cs as well as the calculation and design of Ls and Lp is introduced in detail. In the verification experiments, two kinds of dielectric materials are applied. They result in different performances...
A high power density LLC resonant converter design with extra wide input range is presented. The design consideration for the resonant parameters is discussed. Effect of magnetic component design on the converter efficiency is studied by loss anlysis and experiment. The prototype with switching frequency higher than 500 kHz is built to verify the design.
