The invention relates to a locking device (6) for locking a door (5) of a domestic appliance (1), comprising a locking element (27) for mechanically locking the door (5), comprising a driving element (20) for moving the locking element (27) from an unlocking position in which the door (5) is unlocked into a locking position in which the door (5) is locked by the locking element (27), depending upon a current flow (I) through the driving element (20), wherein the driving element (20) is electrically coupled to a DC voltage source (12), comprising a switching element (22, 23) electrically coupled to the driving element (20) for controlling the current flow (I) through the driving element (20), and comprising a control unit (25) for controlling the switching element (22, 23), wherein the control unit (25) is designed for controlling the current flow (I) through the driving element (20) to emit a sequence of control pulses (30) to the switching element (22, 23). The locking device (6) comprises means for detecting a current voltage value (V) of a DC voltage (VZK) provided by the DC voltage source (12), wherein the control unit (25) is designed to adjust a pulse length (w) of the control pulses (30) as a function of the current voltage value (V).
