Abstract
An electrical system having a plurality of power converters each having an input in electrical communication with a power source and an output in electrical communication with a load. A controller is configured to receive an output power request for the plurality of power converters. The controller can then select at least one power converter of the plurality of power converters to satisfy the output power request based on an efficiency of power conversion of each of the plurality of power converters and an operating lifespan of each of the plurality of power converters and direct the at least one power converter to produce power to satisfy the output power request.
Claims20
An electrical system comprising:
- a plurality of power converters each having an input in electrical communication with a power source and an output in electrical communication with a load;
- and
- a controller configured to:
- receive an output power request for the plurality of power converters;
- select at least one power converter of the plurality of power converters to satisfy the output power request based on an efficiency of power conversion of each of the plurality of power converters and an operating lifespan of each of the plurality of power converters having a remaining usable lifespan based on utilizing one of a lookup table, a continuous function, or a discreate function;
- and
- direct the at least one power converter to produce power to satisfy the output power request.
A method of operating an electrical system having a plurality of power converters, the method comprising:
- receiving an output power request for the plurality of power converters;
- selecting at least one power converter of the plurality of power converters to satisfy the output power request based on an efficiency of power conversion of each of the plurality of power converters and an operating lifespan of each of the plurality of power converters having a remaining usable lifespan based on utilizing one of a lookup table, a continuous function, or a discreate function;
- and
- directing the at least one power converter to produce power to satisfy the output power request.
A vehicle system comprising:
- a traction motor;
- a traction battery in communication with the traction motor;
- a plurality of power converters each having an input in electrical communication with a power source and an output in electrical communication with a load;
- and
- a controller configured to:
- receive an output power request for the plurality of power converters;
- select at least one power converter of the plurality of power converters to satisfy the output power request based on an efficiency of power conversion of each of the plurality of power converters and an operating lifespan of each of the plurality of power converters having a remaining usable lifespan based on utilizing one of a lookup table, a continuous function, or a discreate function;
- and
- direct the at least one power converter to produce power to satisfy the output power request.
