Claim 0:
1. A system comprising:
at least one resistive circuit leg coupled with and disposed between (a) a converter that converts first electric current for a motor and (b) a source of the first electric current for powering the motor, the at least one resistive circuit leg including:
a braking resistor, and
a contactor coupled with the braking resistor;

a first semiconductor switch coupled with and disposed parallel to the at least one resistive circuit leg; and
a second semiconductor switch coupled with the first semiconductor switch and the at least one resistive circuit leg with the at least one resistive circuit leg connected with the first semiconductor switch and the second semiconductor switch in a location that is between the first semiconductor switch and the second semiconductor switch,
wherein, during a regenerative braking mode, a rheostatic braking mode, or a combination of both the regenerative braking mode and the rheostatic braking mode, the contactor is closed and the first semiconductor switch is controlled to alternate between an open state and a closed state to conduct at least some of a regenerated electric current from the motor to the braking resistor to control braking by the motor.
