Abstract:
A method performed in a control unit for opening a contactor device. The contactor device includes a carrier being movable between a closed position in which a current is allowed to flow in a current path and an open position in which the current path is broken. The control unit is configured to enable the movement of the carrier between the closed position and the open position by energizing a coil of an electromagnetic circuit. The method includes: initiating the opening of the contactor device by de-energizing the coil, wherein the de-energizing includes using a demagnetization circuit including a discharge element, the discharge element being arranged to consume energy in the coil; bypassing, at a first point of time, the discharge element; and re-energizing the coil.
