  • Drive system
    Patent number: 11897367
    Abstract: A system comprising resistive circuit legs coupled with and disposed between (a) a converter that converts electric current for a motor of a powered system and (b) a source of electric current for powering the motor, each of the circuit legs including a braking resistor coupled with the converter, a contactor coupled with the braking resistor such that the braking resistor is between the converter and the contactor, and a semiconductor switch coupled with the contactor such that the contactor is between the semiconductor switch and the braking resistor, where, during a regenerative braking mode of operation of the powered system, the regenerated energy from the motor is conducted to the braking resistor and dissipated as heat.
    Type: Grant
