Abstract
In a method for controlling rectifiers of an inductive element for reversible energy transmission first rectifiers are connected to a primary circuit of the inductive element and second rectifiers are connected to a secondary circuit of the inductive element. The first and the second rectifiers are switched in a constant timing ratio. The first rectifiers are controlled by a central signal source with a constant frequency. The second rectifiers are constant frequency. The signals derived from the changing potential at the inductive element. With this method it is possible to provide a control of the rectifiers such that they are switched depending on one another without being directly connected to one another.
