Abstract
An automotive on-board charger topology includes an inverter, an electric machine, and a rectifier that together perform functions such as power factor correction usually performed by a collection of multiple components. This topology also includes a set of contactors that isolate a battery from other components of the charger based on the contactors' configuration.
Claims20
An automotive on-board charger comprising:
- a battery;
- an inverter;
- a rectifier;
- an electric machine, including windings, connected between the inverter and rectifier;
- and
- a controller programmed to operate the inverter such that the inverter, windings, and rectifier together shift a phase between a voltage and current of power from a grid to alter a power factor of the power.
3 more elements
A method comprising:
- responsive to receiving input power from an AC grid, operating a plurality of switches of an inverter such that the inverter, a rectifier, and windings of an electric machine, that is connected between the rectifier and inverter, together shift a phase between a voltage and current of the input power to alter a power factor of the input power.
A vehicle comprising:
- a power system including a battery, an inverter, a rectifier, a transformer, an electric machine connected between the inverter and the rectifier, and a controller programmed to
- during charge, operate the inverter to alter a power factor of power from a grid via the inverter, the rectifier, and windings of the electric machine, and
- after the charge, close at least one contactor such that power between the battery and the inverter bypass the transformer.
