Claims20
An automotive power system comprising:
- a power converter configured to provide power to an electric machine and including a switch having a gate drive resistance;
- and
- a controller programmed to alter the gate drive resistance according to a volume of a radio such that as the volume changes the gate drive resistance changes.
A method comprising:
- varying a gate drive resistance of a switch on an automotive power converter that is arranged to provide power to an electric machine of a vehicle according to data indicative of packet loss associated with wireless communications of the vehicle.
