Abstract: In one embodiment, a method for switching an electrical load having at least one capacitive component and one inductive component in a bridge branch of a bridge circuit comprises a charging of the bridge branch to a first voltage (V1) in a forward switching phase (F), a discharging of the capacitive component of the electrical load in a first open switching phase (O1), a charging of the bridge branch to a second voltage (V2) in a reverse switching phase (R), with the second voltage (V2) being polarized inversely from the first voltage (V1), and a negative charging of the capacitive component of the electrical load in a second open switching phase (O2). A bridge circuit is also provided.

Abstract: This application relates a method and a control circuit for determining a charge current of a battery connected to a modulated load, wherein a current limited power source is connected in parallel to the modulated load and the battery for supplying a load dependent current up to a predetermined current limit to the modulated load and the battery. The control circuit comprises means for measuring a current flowing through the battery; means for indicating an overload condition of the current limited power source; and means for determining the charge current of the battery. The means for indicating an overload condition are configured to indicate an overload condition when a sum of a current drawn by the modulated load and a current flowing into the battery exceeds the predetermined current limit of the current limited power source.
