CONTROL METHOD OF RECUPERATIVE BRAKING OF RAILWAY ROLLING STOCK WITH INPUT SINGLE-PHASE WIDTH-PULSE VOLTAGE CONVERTER Russian patent published in 2020 - IPC B60L7/16 B60L9/24 

FIELD: electrodynamic braking systems for vehicles.

SUBSTANCE: method of control of regenerative braking of railway rolling stock with input single-phase pulse-width voltage converter consists in the fact that delay angle of the main harmonic of the regenerative current from the main harmonic of voltage on the current collector is set and maintained equal to 180 electric degrees. At that, after voltage increase on current collector to maximum permissible value angle of delay of main harmonic of regenerative current from main voltage harmonic on current collector of electric rolling stock is changed to value, ruling out excess of voltage on current collector of maximum permissible value, and stabilizing at preset level. At that, angle of delay of main harmonic of regenerative current from main harmonic on current collector is regulated in range from 180 to 270 electric degrees.

EFFECT: technical result of the invention consists in increasing the duration of recuperative braking, as well as in reducing the value of reactive current in the overhead system.
