Abstract

The invention provides a power inversion device. The device includes a support framework and multiple power inversion modules, wherein the multiple power inversion modules are disposed at a distance from each other in the support framework, and the power inversion modules are mixed silicon carbide power modules. The power inversion modules employ the mixed silicon carbide power modules, an encapsulation dimension is small, loss is low, and miniaturization and lightweight of the entire modules can be improved. The problem that an inverter is large in volume in the prior art is solved.

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to a power inverter device. Background technique [0002] With the rapid development of power electronics technology, the increasingly prominent energy problems and the continuous improvement of people's requirements for reducing environmental load. As an important component in rail transit traction devices, inverters are widely used. [0003] However, the existing inverters use conventional silicon-based power devices, which have the problems of large volume, high mass, and low efficiency, and cannot meet the application requirements. Contents of the invention [0004] The main purpose of the present invention is to provide a power inverter device to solve the problem of large volume of the inverter in the prior art. [0005] In order to achieve the above object, the present invention provides a power inverter device, including: a support frame; a plurality of power inverter m...
