Abstract
A vehicle includes an electric machine. The vehicle includes a controller configured to repeatedly adjust power outputs for the two inverters so that they differ to drive the difference toward zero and such that power provided to the electric machine satisfies demand until the difference falls below a second predetermined threshold. The controller may be configured to adjust responsive to a temperature difference between two inverters associated with the electric machine exceeding a predetermined threshold.
Claims20
A vehicle comprising:
- an electric machine;
- and
- a controller configured to, responsive to a temperature difference between two inverters associated with the electric machine exceeding a predetermined threshold, repeatedly adjust power outputs for the two inverters so that they differ to drive the difference toward zero and such that power provided to the electric machine satisfies demand until the difference falls below a second predetermined threshold.
A vehicle comprising:
- two inverters configured to drive an electric machine;
- and
- a controller configured to, responsive to a power demand falling below a maximum threshold, shutdown a one of the two inverters such that power supplied to the electric machine by the other of the inverters satisfies demand.
A vehicle comprising:
- an electric machine;
- two inverters configured to drive the electric machine;
- and
- a controller configured to, responsive to a difference between aggregated operational factors for each of the two inverters exceeding a predetermined threshold, reduce power output for one of the two inverters and raise power output for the other of the two inverters such that power provided to the electric machine satisfies demand.
