Abstract

A circuit arrangement that has an energy source that can provide a charging voltage for charging an electrical energy storage unit in a charging circuit when it is connected to an energy supply, wherein it is possible to represent the charging voltage using an alternating quantity, and that has a capacitor circuit having a first capacitor element, a first valve element, and the energy source, wherein the first capacitor element is charged by the energy source via the first valve element if the charging voltage is negative, so that, if the charging voltage is positive, the voltage over the first capacitor element has the same orientation in the capacitor circuit, in terms of sign, as the charging voltage, and the voltage over the capacitor element.
