A system for a vehicle including an inverter electrically between a motor and traction battery, and a controller configured to operate the inverter at one of a predefined set of discrete frequencies selected according to rotor-torque-based probability weights corresponding to each of the discrete frequencies such that a probability that the inverter operates at the one changes as rotor torque changes.
