An adaptable electrical braking system for an electrical propulsion system of a traction vehicle is provided. The electrical braking system is configured to dissipate electrical energy in a plurality of resistor grids. The braking system includes a braking system assembly including a baseline chopper circuit topology. The baseline chopper circuit topology includes a first semiconductor-based circuitry in an enclosure for accommodating the first semiconductor-based circuitry. The braking system further includes a second semiconductor-based circuitry electrically coupled to the first semiconductor-based circuitry to produce a chopper including a chopper circuit topology fully contained in the enclosure. The second semiconductor-based circuitry includes a circuit topology selectable to adapt the baseline chopper circuit topology to meet distinct operational requirements to be fulfilled by the braking system.
