Abstract

The invention discloses a transformer and an inductance magnetic integration structure, and belongs to the technical field of power electronics. The transformer inductance magnetic integration structure is composed of a pair of magnetic cores including at least four magnetic columns, a primary winding and a secondary winding. One transformer and two inductors can be integrated in one magnetic core, flexible configuration of the winding structure can also be realized, any transformer turn ratio, any excitation inductance and leakage inductance ratio can be realized and the magnetic core loss can also be reduced and the efficiency can be improved. Meanwhile, the integrated structure greatly reduces the volume and the weight of power magnetic parts so as to be helpful to improve the power density of the converter. The structure is particularly suitable for various applications such as bidirectional CLLC resonant converters and the like where transformers and inductors are used for high-frequency, high-efficiency and high-power density power conversion.

Description

technical field

[0001] The invention relates to a transformer and an inductive magnetic integrated structure, which belongs to the technical field of power electronics. Background technique

[0002] With the development of modern power electronics technology and the birth of high frequency switching devices such as SiC and GaN, high frequency, integration and modularization have become the development trend of switching power supplies. Facts have shown that increasing the switching frequency can reduce the size of the device, improve power density and reliability, and reduce switching noise. Resonant converters are favored by the industry for their excellent soft switching, high efficiency, and high power density, and are widely used in server power supplies, new energy electric vehicle charging piles, and other occasions. Among them, due to the symmetry of its structure, the CLLC resonant converter can realize bidirectional power transmission, and can realize soft switchin...
