The invention relates to a method for control of a frequency converter, in particular, for generation of effective power for inductive heating, whereby a load tuned circuit is provided on the converter. The working point of the converter is pre-determined on the basis of the change in resonant frequency of the load tuned circuit and at least one further influencing parameter. The invention further relates to a converter which carries out a pre-determination and a corresponding compensation of switching frequency of the converter switch with at least three memory values.
