A method and a circuit arrangement (1) for charging and discharging a load (4) with a capacitive component is proposed, having an energy source (3) which provides a direct voltage between a positive (+) and a negative (-) or earth terminal, a charging circuit and a discharging circuit, each of which has a coil (6, 9), and switching means (7, 8, 12, 13) controlled by a controlling system (2). The charging and discharging of the load (4) is intended to be controlled in an improved manner with a method and a circuit arrangement of that kind. For that purpose the controlling system (2) compares a report-back signal (C, H, K, L) from the circuit arrangement, or a signal derived therefrom, with an external desired value signal (Vin), and actuates the switching means (7, 13, 8, 12) as a function of a difference in the two signals. The charge is supplied to or down from the load in the form of quanta, the magnitude of the quanta being variable.
