    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.

    Abstract: A method in a control unit for closing a contactor device. The control unit is configured to enable the movement between the closed and opened position by energizing a coil of an electromagnetic circuit. The method includes applying a voltage over the coil; determining, during a first period of time, current through the coil and voltage over the coil and estimating based thereon model parameters for a model predicting the behavior of the current through the coil if the contactor device were to stay in an open position, and measuring, after the ending of the first period of time, current through the coil and determining a difference between, on the one hand the measured current and, on the other hand a predicted current of the model, and repeating the measuring and determining until a state change from open position to closed position is detected by the difference in current.

    Abstract: A load control device for controlling an amount of power delivered from an alternating current (AC) power source to an electrical load includes a relay operable to be coupled in series electrical connection between the AC power source and the electrical load. The relay has one or more relay contacts. The load control device includes a zero-cross detector operable to detect zero crosses of the alternating current and to generate zero cross signals, and a controller operatively coupled to a control input of the relay and the zero-cross detector for rendering the controllably conductive device conductive and non-conductive. The controller determines a relay actuation adjustment such that the contact reliably completes bouncing just prior to a zero cross and may initiate an actuation of the relay based on the actuation adjustment and the zero cross signal.
