A vehicle includes a traction motor having resonance frequency zones, an inverter including switches arranged to drive the traction motor, and a controller. The controller operates the switches only within specified sets of carrier frequencies such that noise side hands corresponding to the carrier frequencies fall outside the resonance frequency zones.
