Abstract:
1. A kit for reconfiguring an electrical braking system for a traction vehicle, the electrical braking system comprising a chopper having electromechanical-based circuitry and semiconductor-based circuitry, said electrical braking system to be reconfigured to an electrical braking system comprising a chopper exclusively having semiconductor-based circuitry, the electromechanical-based circuitry being externally disposed with respect to an enclosure for accommodating the semiconductor-based circuitry in the chopper having electromechanical-based circuitry and semiconductor based circuitry, said kit comprising: a braking system assembly comprising a chopper having a first chopper circuit topology, said first chopper circuit topology comprising a first semiconductor-based circuitry having a footprint that defines at least one cavity in an enclosure for accommodating the first semiconductor-based circuitry, said enclosure constituting the enclosure for accommodating the semiconductor-based circuitry in the chopper having electromechanical-based circuitry and semiconductor based circuitry; and a second semiconductor-based circuitry to be arranged in the at least one cavity in the enclosure for accommodating the first semiconductor-based circuitry, wherein the second semiconductor-based circuitry is adapted to be electrically coupled to the first semiconductor-based circuitry to produce a chopper comprising a second chopper circuit topology fully contained in the enclosure, the second chopper circuit topology operable without any electromechanical-based circuitry.
