Abstract

The invention discloses a high-power cross type decoupling integrated ultrahigh frequency transformer structure which comprises a magnetic core middle column, N pairs of magnetic core side columns are arranged outside the magnetic core middle column, N is a positive integer, and the N pairs of magnetic core side columns are circumferentially arranged on the magnetic core middle column; windings are arranged on the magnetic core middle column and the magnetic core side columns; the magnetic core side column is U-shaped, and two ends of the magnetic core side column are fixed with the magnetic core middle column; and the windings on the symmetrical magnetic core side columns are connected. A plurality of transformers are decoupled and integrated on the same magnetic core at the same time, so that the transformers do not influence one another during working; and the magnetic core is made of a magnetic material with high magnetic conductivity. According to the integrated high-frequency transformer, the number of discrete transformers and the occupied space volume of the discrete transformers can be reduced, the volume of a magnetic core can be reduced when the integrated high-frequency transformer works under ultrahigh frequency, the power density of the power converter adopting the integrated high-frequency transformer is greatly improved, and meanwhile leads between devices can be saved.

Description

technical field

[0001] The invention relates to the technical field of high-frequency transformers, in particular to a high-power "crossover" type decoupling integrated high-frequency transformer structure. Background technique

[0002] In recent years, with the use of new energy and the development of power electronic technology, the number of power converters required by the power supply system is increasing, and its function is to realize the transmission and conversion of electric energy. As an important indicator in power converter systems, power density has been extensively studied. The high-power high-frequency transformer is an indispensable component in the isolated power converter, which has the function of transmitting energy and electrical isolation. However, when there are multiple high-frequency transformers in the power converter, the space occupied by them is large, resulting in lower power density. Therefore, the use of magnetic integration technology to i...
