Abstract: An exemplary contactor control system and method to reduce the amount of sound during the translation of an automotive contactor from a closed state to an open state is provided. The contactor has an electrical coil and first and second electrical contacts. The control system includes a microcontroller and a high side driver circuit. The microcontroller generates a pulse width modulated signal that is applied to the high side driver circuit and decreases a duty cycle thereof to decrease a first control voltage applied to the electrical coil over a time interval. The microcontroller maintains a duty cycle for another time interval to maintain the contactor in the closed operational state. Next, the microcontroller decreases the duty cycle to reduce a speed of a contactor armature prior to contacting a stop member to reduce an amount of sound while transitioning the contactor to the open state.
