Abstract: An electric power system includes an inverter device coupled with a motor. The inverter device receives from the motor electric energy generated by dynamic braking of the motor. An energy storage device is coupled with the inverter device, and a variable resistive component is disposed between the inverter device and the energy storage device. The variable resistive component controls a direction of conduction of the electric energy from the inverter device toward the energy storage device, a resistive grid, or a system load. The variable resistive component controls the direction of conduction of the electric energy from the inverter device based on a first amount of the electric energy conducted from the inverter device, a transfer rate of the electric energy conducted from the inverter device, or one or more characteristics of the energy storage device.

Abstract: A controller may control a transfer of electric energy between two or more energy storage devices of a plurality of energy storage devices, at least one energy storage device being disposed onboard a vehicle system, and identify a transfer restriction on the transfer. The controller may change a transfer characteristic based at least in part on the transfer restriction. A system may include a controller to monitor transfer of electric energy between one or more energy storage devices disposed onboard one or more vehicle systems and energy transfer substations that are offboard the one or more vehicle systems. A method may include controlling a transfer of electric energy between two or more energy storage devices, at least one energy storage device being disposed onboard a vehicle system, identifying a transfer restriction on the transfer, and changing a transfer characteristic based at least in part on the transfer restriction.

Abstract: A vehicle brake control system includes an inverter configured to convert direct current (DC) into an alternating current (AC) for a motor of a vehicle. The inverter includes switches configured to convert the DC to the AC, as well as a resistor and a bypass switch disposed in series with each other. A controller is communicatively coupled with the inverter switches and the bypass switch. The controller opens the bypass switch so that the DC is conducted through and converted into the AC for the motor during a motoring mode. The controller closes the bypass switch so that regenerated current from the motor is conducted through the resistor of the inverter for partial dissipation of the regenerated current during a dynamic braking mode.
