Classification: CPC B  H | IPC B

Claim 9:
10. A system comprising:
one or more first semiconductor switches;
one or more second semiconductor switches;
two or more inductors, with each inductor of the two or more inductors configured to be disposed onboard a powered system and selectively coupled with a source of first electric current and a converter that converts the first electric current for a motor of the powered system, the two or more inductors each coupled with nodes located between the one or more first semiconductor switches and (a) one or more diodes or (b) the one or more second semiconductor switches, second semiconductor switches coupled with a converter;
contactors connected in parallel with each other between the source of the first electric current and the converter; and
braking resistors connected in parallel with each other, each of the braking resistors connected in series with a different contactor of the contactors between the contactor and the converter;
wherein, the first semiconductor switch of the one or more first semiconductor switches is coupled with a contactor of the contactors connected in parallel with each other, such that the contactor of the contactors connected in parallel with each other is between the first semiconductor switch of the one or more first semiconductor switches and the braking resistors,
wherein, during a regenerative or rheostatic braking mode of operation of the powered system, regenerated electric current from the motor of the powered system is conducted to the braking resistors and dissipated as heat, based on which of the contactors or the one or more first semiconductor switches are closed.
