摘要：
The invention relates to a method for adjusting the impedance of a load (28) to the output impedance of a power generator (40), comprising the following steps : a. generating a power by means of a power generator (40); b. supplying the power to a load (28) via an impedance adjustment assembly (10) with at least one reactance (18, 20, 22) that can be changed via a control element (12, 14, 16), wherein the impedance adjustment assembly (10) converts the load impedance (27) at the input of the load (18) into a transformed load impedance (29) at the input of the impedance adjustment assembly (10); c. detecting or determining a power reflected in the load (28) or at least a variable relating thereto; d. based on the reflected power of the at least one related variable, checking whether a maladjustment has occurred; e. determining a trajectory (50) in a complex load plane, in particular in the Smith chart (60), according to at least one predetermined criterium; f. controlling the at least one control element (12, 14, 16) such that the transformed load impedance (29) follows the trajectory (50).
