  • Method for Switching an Electrical Load in a Bridge Branch of a Bridge Circuit, and Bridge Circuit
    Publication number: 20110309803
    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.
