Abstract
In a method for operating an energy converter that couples a first supply network to a second supply network by converting electrical energy via a switch element, the switch element is operated in a switching operation and a supply-network current for one of the supply networks is adjusted depending on a comparison of the supply-network current with a reference current. In a first operating mode for the switching operation, an electrical voltage of one of the supply networks is set by a PWM method on the basis of the comparison, and a second operating mode is provided, in which the switch element is switched when, during the comparison, a difference between the supply-network current and the reference current is greater than a first predefined relative switching value and/or is smaller than a second predefined relative switching value, wherein the first and second operating modes are alternated during the operation.
