The invention refers to an apparatus for driving a load with a drive signal. The apparatus includes an AC voltage source, a DC voltage source, a capacitor and a control apparatus. The AC voltage source outputs an AC voltage. The DC voltage source outputs a DC voltage. The capacitor includes a first terminal and a second terminal. The AC voltage source is connected to the first terminal, and a signal output is connected to the second output. The control apparatus controls, depending on a voltage present at the signal output, a connection between the DC voltage source and the second terminal. Furthermore, the invention refers to a corresponding method as well as to a device.
