ABSTRACT:
A kit and method for reconfiguring an electrical braking system for a traction vehicle are provided. The kit may include a braking system assembly including a chopper having a first chopper circuit topology. The first chopper circuit topology includes a first semiconductor-based circuitry having a footprint that defines at least one cavity in an enclosure for accommodating the first semiconductor-based circuitry. This enclosure constitutes the enclosure for accommodating the semiconductor-based circuitry in the chopper having electromechanical-based circuitry and semiconductor based circuitry. A second semiconductor-based circuitry is arranged in the at least one cavity in the enclosure for accommodating the first semiconductor-based circuitry. The second semiconductor-based circuitry when electrically coupled to the first semiconductor-based circuitry produces a chopper comprising a second chopper circuit topology fully contained in the enclosure. The second chopper circuit topology is operable without any electromechanical-based circuitry.
