Abstract
The invention relates to a circuit configuration for the automatic tuning of a matching network (2) disposed between an electrical energy source (1) and a load (3). Herein two measured signals (U.sub.E, U.sub.1) are received from which are formed the magnitudes of three signals (U.sub.E, U.sub.1, I.sub.E) from which, in turn, the control values x.sub.1, x.sub.2 are determined for the setting of the matching network (2).
