Abstract

A capacitor block comprises n capacitors C1 to Cn, (3 (n - 1) + 1) switches, and two terminals conducted out of the capacitor block. In each case, three switches are located between two capacitors, two switches connect identical capacitor plates, and one switch connects different capacitor plates. The last capacitor is conducted with the lower plate thereof via the (3(n - 1) + 1)th switch to the terminal having reference potential, and the upper plate is conducted directly on the other. The capacitor block is switched by means of a processor by successive switching, starting from the purely parallel circuit, to a subsequent smaller overall capacitance and thereby has discharge intervals, in which the time constant τ = 1/n RC acts. In order to avoid charge reversals in parts of the capacitor block, the capacitor circuit of the capacitor block is switched at least one cyclically during a discharge interval while maintaining the just switch overall capacitance.
