Abstract

A switch signal is produced in order to form a switching time t2 in order to adapt the switch frequency in a converter, such that the waited zero crossing of the load circuit (13) for the point in time t3 is determined and the switching time is derived therefrom. The switching point in time t2 and the waited zero crossing of the load circuit (13) advances about the load circuit. The converter is controlled in such a manner that switching loss is minimised.
