Power electronic transformer structure

Abstract

The invention relates to a power electronic transformer structure. The power electronic transformer structure comprises a support, a high-frequency transformer, a base, high-voltage modules and a low-voltage module. The high-voltage modules are respectively located at the front portion, the top portion and the rear portion of the support; the low-voltage module is located at the bottom portion ofthe support; and the high-frequency transformer is located at the middle portion of the support. The support employed by the transformer structure is an epoxy support, the support is internally provided with the high-frequency transformer, the high-voltage modules and the low-voltage module are arranged at the outer portion of the support so that the transformer structure is more compact, uniform,and the functional structure has the uniqueness and innovation;; further, the support is the epoxy support so that the problems that the epoxy resin is difficult to solidify and form after pouring and the deformation is difficult to guarantee due to the fact that the dead weight of the iron core and the coil of the high-frequency transformer is heavy are solved; and moreover, the insulation requirement of the whole structure of the power electronic transformer is guaranteed, and the yield of products is greatly improved.

Description

technical field [0001] The invention relates to a transformer structure, in particular to a power electronic transformer structure. Background technique [0002] With the continuous development of modern power grids, more and more distributed power generation systems and distributed energy storage systems need to be connected to the power grid. When new energy power generation systems are connected to the grid, interface equipment is required to provide multi-level voltage adjustment and AC-DC intercommunication conversion. , intelligent energy management and other functions, while the traditional transformer has limited functions and cannot provide the above functions. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a power electronic transformer structure. [0004] The technical solution provided by the present invention is: a power electronic transformer structure, the transformer st...
