Abstract

The advancement of technology requires that power supplies have high efficiency and high power density. The current doubler rectifier has been presented as a solution to decrease the transformer secondary power loss and increase the power efficiency. In this paper, the unified equivalent coupled inductor circuit models are constructed for different current doubler rectifier integrated magnetic structures. Based on the finite element method analysis, the impedance matrixes and coupling coefficient matrixes of different structures are compared. The efficiency and performance of different structures are also experimentally studied.
