A capacitive load charging/discharging device, including a first capacitor, a down-up converter including a first and a second switching element connected across the first capacitor, wherein a connecting point of the switching elements is connected to a first output terminal of the converter through a main coil. The device further includes an output circuit with a capacitive load arranged between first and second output circuit terminals, which are connected to output terminals of the converter. A discharge circuit is formed with the output circuit, the main coil and the second switching element, including an additional capacitor which is connected to a charging circuit for charging to a specified voltage, wherein the polarity of the voltage corresponds to that of the load voltage in the charged state of the capacitive load.
