    摘要: A hybrid energy system for propelling an off-highway vehicle includes an engine rated at a first power capacity, and a power converter driven by the engine for providing primary electric power. A traction motor system receives the primary electric power, the traction motor system propelling the off-highway vehicle in response to the primary electric power, and the traction motor system further including a dynamic braking mode of operation. An energy storage medium captures electrical energy generated by the traction motor system in the dynamic braking mode of operation, the energy storage medium transferring a portion of the captured energy to the traction motor system to augment the primary electric power, wherein the traction motor system is rated at a second power capacity exceeding the first power capacity.

    摘要: A system is provided that includes an engine coupled to an alternator; a radiator fan motor in electrical communication with the alternator, and that is mechanically decoupled from the engine; an energy storage device in electrical communication with the alternator and the radiator fan motor; and one or more traction motors in electrical communication with the energy storage device, the radiator fan motor, or both. Electricity provided through dynamic braking can power the radiator fan motor upon generation of the electricity, or it can be stored in the energy storage device for use later in powering the radiator fan motor.

    摘要: A communication method includes detecting at a gate drive unit a change of state of a command signal that is received via a command link of the gate drive unit and initiating, responsive to the change of state of the command signal, a blanking period in which the gate drive unit will process as incoming data any further changes of state of the command signal. The method also includes receiving incoming data at the gate drive unit, by processing modulations of the command signal, within the blanking period.
