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.

Abstract: A system may be provided that includes an energy storage device, and an inverter electrically coupled to the energy storage device. The system also includes a passive filter electrically coupled between the energy storage device and the inverter. The passive filter includes a first coupled-inductor and at least one first bypass capacitor. The first coupled-inductor includes at least two magnetically coupled windings. The passive filter is configured to reduce or eliminate alternating current at the energy storage device.
