AUTOMATIC REGENERATIVE-RHEOSTATIC BRAKING SYSTEM Russian patent published in 2018 - IPC B60L7/22 B60L9/02 H02P3/12 H02P3/14 H02P7/18 

FIELD: transport machinery.

SUBSTANCE: invention relates to electrodynamic brake systems for vehicles. Braking system automatic recuperative-rheostat contains a power supply, two traction motors of direct current, interacting with a block of diodes, intended for transition to the regenerative braking mode, and with a block of resistors connecting in the rheostatic braking mode and a field programmable gate array (FPGA). FPGA is configured to receive and process in parallel signals from sensors that monitor the current level and from the voltage sensor, and digital signals coming from the electric locomotive control system. FPGA simultaneously generates the output control digital signals that are fed to the drive converter of the DC bus excitation windings, in the module of protocol information exchange with connected devices and in digital-analog converters for interaction with analog systems.

EFFECT: technical result of the invention is to increase the reliability of the electrodynamic brake.
