Abstract: The present invention is directed to a control strategy for operating a plurality of prime power sources during propulsion, idling and braking and is applicable to lar ge systems such as trucks, ships, cranes and locomotives utilizing diesel engines, gas turbine engines, other types of internal combustion engines, fuel cells or combinations of these that require substantial power and low emissions utilizing multiple power plant combinations. The present invention is directed at a general control strategy for a multi-engi ne systems where the power systems need not be of the same type or power rating and may even use different fuels. The invention is based on a common DC bus electrical architecture so that prime power sources need not be synchronized.

Abstract: The present invention is directed to a power control architecture for a vehicle, particularly a locomotive, in which a number of energy sources are connected to a common electrical bus and selectively provide energy to the bus based on the relationship between their respective output voltages and the bus voltage.

Abstract: The present invention is directed to a locomotive comprising energy storage units, such as batteries, a prime energy source, such as a diesel engine, and an energy conversion device, such as a generator. The locomotive comprises one or more of the following features: a separate chopper circuit for each traction motor and a controller operable to control separately and independently each axle/traction motor.

Abstract: In one embodiment, a multi-engine locomotive includes at least one converter to convert mechanical energy outputted by the engines to Direct Current (DC) electrical energy, a traction motor, and a DC bus connected to the engines, converter, and traction motor. The engines are configured to provide a power-per-length and/or power density that is greater than the power-per-length and/or power density of a single-engine locomotive having a power rating approximately the same as the cumulative power rating of the engines in the multi-engine locomotive.

Abstract: A system and method of dynamically equalizing battery voltages with low inherent power losses in a string of series connected electrochemical batteries is disclosed. The method includes steps of charging/discharging a group of batteries using magnetic storage in a transformer with bipolar magnetic excursion, individually isolated circuits and pulsed energy transfer. A method of exchanging current between batteries using direct current transfer between them and limiting inductance is also disclosed. Using this method, battery voltage may be measured from a n isolated circuit, thus enabling information transfer to a central monitoring system. The method also has the benefit of providing an estimation of battery intern al resistance from isolated circuits in the series of batteries.
