FIELD: electrical engineering.
SUBSTANCE: machine with electric transmission braking energy absorption device comprises braking resistor arranged at cooler, braking resistor control device and power switch to connect braking resistor to transmission power buses. Transmission also includes generator and/or energy accumulator, electric motor, as well as a transmission control system containing controls and controllers, which include a power converter based on power IGBT-modules with the possibility of performing reversible power exchange between the power buses and the electric motor. IGBT-modules of the power converter are additionally installed on the cooler.
EFFECT: simplified design, higher reliability of the device.
