A current converter device comprises a current converter module, a front-end access unit, a fixing discharge resistance circuit, a sensor detection unit and a traction control unit. The front-end access unit is used for being connected with a power supply, the current converter module is used for outputting the adjusted power supply to a traction motor, the traction control unit controls the current converter module through work signals and external input signals collected by the sensor detection unit, a filter electric reactor cavity in a box body is located at one end of the inside of the box body and used for arranging a filter circuit in the front-end access unit, and a power supply board and a DCU cavity are located below the other end of the inside of the box body and used for arranging the traction control unit and the power supply board; the current converter module and the sensor detection unit are located in a cavity of the current converter module, the current converter module is located above the power supply board and the DCU cavity, the sensor detection unit is divided into two parts, one part is located above the current converter module, and the other part is located below the middle portion of the box body. The current converter device has the advantages of being high in integration level, easy to maintain, good in cooling effect and the like.
