IMPROVEMENT OF ENERGY EFFICIENCY OF THE SYSTEM OF ELECTRIC BRAKING OF ROLLING STOCK
The analysis of the most used electric braking systems in terms of their energy performance is carried out. A combined method of braking and a variable-structure electric braking system for DC motors are proposed. In the braking mode, the motors operate as alternators, and the current in the excitation windings is controlled by a converter.
