Description
Technical field
The present invention relates to a kind of power module mounting structure, be specifically related to a kind of mounting structure of IGBT module.
Background technology
In the power electronics industry, owing to the power that every IGBT module can be born is limited, often need to adopt many module parallel connections, to improve power capacity.The technology of many module parallel connections focuses on solving the current-sharing of each module, and solving current-sharing has very big specification requirement and technology difficulty.Common way is that each output stage in module adopts single copper bar or cable to connect, and is difficult to guarantee the current-sharing of each module, causes bearing the big module damage of electric current easily; And also inconvenience is installed, structure is not compact.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, designed and developed out the equal flow problem of each IGBT module of the fine solution of a kind of energy, and compact conformation, simple IGBT module copper bar installation structure.
The present invention is achieved by the following technical solutions:
A kind of parallel IGBT module copper bar installation structure, at least one IGBT module is installed on the copper bar, and described copper bar comprises short circuit copper bar and switching copper bar; The switching copper bar is fixedly mounted on the short circuit copper bar; Described at least one IGBT module is installed on the short circuit copper bar.
A kind of parallel IGBT module copper bar installation structure, described switching copper bar is installed in the body top of short circuit copper bar; Described IGBT module is installed in short circuit copper bar bottom.
A kind of parallel IGBT module copper bar installation structure, switching copper bar and IGBT module offer at least one slotted eye on short circuit copper bar body between the installation site on the short circuit copper bar.
A kind of parallel IGBT module copper bar installation structure, the switching copper bar is installed on the short circuit copper bar between two parties.
A kind of parallel IGBT module copper bar installation structure, described slotted eye is opened on the short circuit copper bar between two parties.
Beneficial effect of the present invention is as follows: adopt the current-sharing copper bar that each output stage of module is connected in parallel, the problem of the current-sharing of fine each module of solution of energy.And compact conformation when making the module parallel connection is convenient to install.The short circuit copper bar has the long slot bore that is no less than a blocking-up electric current on matrix, change current path, reaches the effect of module parallel current-sharing.Switching copper bar and slotted eye all are placed on the short circuit copper bar between two parties, make the module parallel connection can reach better current-sharing effect.
