TWO-STEP stabilizer system voltage locomotive traction of passenger cars powered from undercar generator

摘要

The invention relates to the field of rail transport electrical means and can be used to stabilize the system voltage onboard electric locomotive traction of passenger car. The technical result is to increase the stability of the output voltage when an input voltage jumps especially during prolonged vehicle is moving at slow speed. The technical result is achieved in that the two-stage stabilization device voltage onboard network passenger car locomotive traction powered from an undercar generator comprises uncontrollable power rectifier adapted for connection to the undercar generator AC output uncontrolled power rectifier is connected to the input of the first voltage detecting unit, an output connected to an input current adjusting unit undercar excitation generator and the first input of the power DC / DC transformation the forming second and third inputs are connected to outputs of the second voltage measuring unit and a battery charging current measuring unit.
