  "textContent": "Methods and systems are provided for adapting pulse width modulation with randomized zero-sequence components for control of an electrified powertrain of a vehicle. In one example, a method may include determining a zero-sequence voltage of an electric machine of the vehicle based on a random distribution, and adjusting a voltage reference signal of the electric machine based on the determined zero-sequence voltage to decrease ambient acoustic noise in the vehicle. In this way, spectral energy dispersion of pulse width modulated control of the electric machine may be increased without affecting torque production of the electric machine.",
