An electrified vehicle includes a traction battery coupled to an electric machine that provides propulsive force, an auxiliary battery, a voltage converter coupled to the traction battery and configured to convert traction battery voltage to auxiliary battery voltage, and a controller programmed to control the voltage converter to provide either a non-oscillating voltage above a first voltage threshold, or an oscillating voltage having a peak below the first voltage threshold based on a vehicle start signal and a vehicle brake pedal position signal. The controller may control the voltage converter to provide the non-oscillating voltage in response to the vehicle start signal being received while the brake pedal position signal indicates a released brake pedal, and to provide the oscillating voltage in response to the vehicle start signal being received while the brake pedal position signal indicates a depressed brake pedal.
